Audi A4 (2008 – 2015) At A Glance
High quality interior with plenty of space. Excellent steering and handling. Available with quattro four-wheel drive. Frugal 2.0 TDI. Improved for 2012 with more efficient engines.
Doesn’t handle quite as well as a BMW 3 Series. CVT gearbox used with 2.7 V6 diesel.
When the new Audi A4 saloon was launched in 2008, the small executive market gained another frontrunning contender alongside the BMW 3 Series and Mercedes C-Class. This Audi A4 handled, steered and rode with the best of them, while also delivering on Audi’s usual high standards of cabin finish. A wide range of engines appealed to company and private buyers, and there was the usual option for four-wheel drive.
The Audi A4 of 2008 marked a significant improvement in the way the upmarket small saloon handled, steered and rode the bumps. It is seriously worth considering if you are looking for a top used car buy, and our Audi A4 review will explain why.
Gone was the too firm suspension of the previous model and in came a fluency that made the Audi A4 a much closer contender to the BMW 3 Series as a driver’s car. It also delivered the comfort of a Mercedes C-Class alongside the understated appeal of the Lexus IS or Sweden’s Volvo S60.
It helped that the Audi A4 was based on the same platform as the Audi A5, which is effectively a hatchback version of the Audi A4 four-door. Most Audi A4s remained front-wheel drive, but with the weight of the engine better balanced in the car to deliver that improved dynamic feel.
Quattro four-wheel drive also remained a key component of the Audi A4’s appeal to both private and company buyers. This system could deliver all-weather confidence without ever feeling clunky or intrusive during normal driving conditions, and crucially it didn’t impact unduly on fuel economy or carbon dioxide emissions.
Where the Audi A4 did show a weak link was the CVT (continuously variable transmission) used with the 2.7-litre turbodiesel. It never feels truly settled while also being sluggish when it comes to acceleration. Much better is the semi-automatic S tronic used with the 3.0-litre V6 diesel, although most drivers will be best served by the 1.8 TFSI turbo petrol or 2.0-litre turbodiesel motors.
Inside, the Audi A4 is roomier than the contemporary BMW 3 Series and solidly put together. It’s not the most dramatic dash to look at yet it’s functional and there’s an early infotainment screen operated by Audi’s simple MMI controller.
On top of this, the Audi A4 scored well for safety and equipment, so a used buyer won’t feel shortchanged. The higher spec S line models come even more loaded, though they also have a slightly firmer edge to their suspension set-up.

Audi A4 (2008 – 2015) handling and engines
- Engines range from 1.8 TFSI 120 to 3.2 FSI quattro
- Readers report Real MPG to be between 20–66 mpg
Audi A4 (2008 – 2015): Handling and ride quality
Where the previous Audi A4 had been safe and stodgy when it came to corners, this new saloon was a revelation. Audi had worked incredibly hard to engineer its small executive saloon to be more agile, nimble and yet also offer improved comfort. Laudably, all of its efforts paid off.
Approach a corner in this era of Audi A4 and you can feel as much as you need to through the steering to judge the right amount of braking, grip and turning input required. It’s not as pin-sharp as a BMW 3 Series, but the Audi A4 is fun to drive briskly.
Most are front-wheel drive models that offer plenty of margin if it’s wet or greasy on the roads, while the Quattro model (standard with the more potent V6 versions) makes rapid, assured progress in all conditions.
On lumpy roads, the Audi A4 does a very good job of soothing away the bumps. If you have an S line model with its firmer standard suspension set-up and larger wheels, you will notice more surface jibes.
However, Audi did offer new customers the option of buying the S line with the standard, more compliant suspension, which was a fine compromise.
Audi A4 (2008 – 2015): Engines
Both the petrol and diesel line-ups divide into two clear camps with the Audi A4. There are the smaller capacity four-cylinder units and then the bigger V6 motors.
With the petrols, the 3.2 FSI V6 is quick enough and sounds good, but offers little extra over its 2.0-litre turbo petrol alternative. If you really want a turn of pace, the S4’s 333PS supercharged 3.0-litre motor is the one to have, although it comes with high running costs.
V6 power in the diesels is taken care of by the 2.7- and 3.0-litre V6 motors with, respectively, 190 and 240PS. If you are lured in by the smooth running of these engines, we’d recommend the 3.0-litre as the 2.7 offers not much more power than its 2.0-litre four-cylinder alternative and it comes with a slushy CVT (continuously variable transmission) instead of the 3.0’s traditional and better auto ’box.
The 3.0-litre model also has Quattro four-wheel drive included as standard.
Petrol fans can pick between the 1.8- and 2.0-litre TFSI units. Which you want depends on how quickly you want to go as the larger capacity motor is brisker. The 2.0-litre also gives you the option of front- or four-wheel drive. We'd take this engine with front-drive for the best mix of pace and economy.
If outright fuel efficiency is your target, the Audi A4’s 2.0-litre diesel delivers. It comes in a variety of power outputs, but best of the bunch for the cost-conscious is the 136PS Ultra model that offers up to 69mpg.
None of these diesels is the most refined in the class, but they pull keenly and the six-speed manual gearbox fitted to most is light and precise to use.
Audi A4 (2008 – 2015): Safety
When tested by Euro NCAP in 2009, this Audi A4 scored a full five stars. It did very well for adult occupant safety thanks to front, side and head airbags as standard in all versions.
Every Audi A4 also comes with ESC traction control and a speed limiter for the cruise control. There’s also a seatbelt reminder and ABS anti-lock brakes, but that's about it.
Audi A4 (2008 – 2015): Towing
If you’re planning on towing, the Audi A4 can pull an unbraked trailer of up to 750kg. With brakes on the trailer, you’re fine up to 1500kg on all models, and some can pull up to 1700kg, such as the the 1.8 TFSI versions.

Audi A4 (2008 – 2015): Practicality
Whether you’re sat in the driver’s seat or the middle of the back bench, this generation of Audi A4 is more accommodating than its rivals of the same time.
A BMW 3 Series may be more driver-focused, but the Audi A4 isn’t far off and the steering wheel, pedals and gear lever are all right where you instinctively feel they should be positioned. Nothing distracts you from the task at hand.
It’s the same with the driver’s view in all directions, with only the high boot line needing a little caution when reversing. Then again, many Audi A4s of this generation came with rear parking sensors to cancel out this concern. You also have brilliantly clear dials and simple controls on the centre console for the ventilation and other functions.
In the back seats, the Audi A4 saloon is better at fitting in adults and lankier kids than its key rivals. Deep footwells help to offer more kneeroom and the roof line is less steeply angled than the Audi A5’s to offer greater headroom.
Step to the back and the Audi A4’s boot is generous with 480 litres in normal use. Tip the 60-40 split and fold back seat down and you can liberate as much as 962 litres of cargo room.
Audi A4 (2008 – 2015): Quality and finish
Audi is famed for its attention to detail and tight shutlines. This generation of Audi A4 is a perfect example of this.
As a used car, the only likely signs of wear on the Audi A4 will be to the driver’s seat bolster and some of the switches on the dash that take on a shiny glow. However, there’s every chance the Audi A4 will still be functioning as it should thanks to good overall reliability.
Audi A4 (2008 – 2015): Infotainment
Audi’s MMI interface was, relatively speaking, in its infancy when the 2008 Audi A4 was introduced. This means there’s no touchscreen and the display’s resolution and graphics appear basic.
However, it’s very easy to use with the MMI controller down next to the gear lever, so it still shows some of the latest systems how it can be done in this respect.
Audi A4 (2008 – 2015) value for money
Audi A4 (2008 – 2015): Prices
Starting point for an early Audi A4 saloon of this generation is around the £4500 mark, which gets you a car with less than 85,000 miles and a full service record. You’ll have a choice of engines, although the most common will be the 2.0-litre turbodiesel with six-speed manual gearbox.
At the other end of the spectrum, a late 2015 model with the most efficient diesel engine will need a cash sum of around £13,000.
Audi A4 (2008 – 2015): Running Costs
The most fuel efficient Audi A4 saloon is the TDI Ultra 136PS model that can offer an official combined consumption of 68.9mpg, although this was measured under the older method.
In the real world, that translates to about 60mpg so it’s still good overall. With the more powerful diesel engines, 50mpg is possible, while the 1.8 petrol can give 40mpg in daily use.
With insurance ranging from Group 19 to 36 depending on engine and trim, the Audi A4 needn't be pricey to get cover for. Nor should road tax be an issue as most fall in the lower brackets with an annual cost as low as £20. However, the heavier emitting models could cost as much as £675 per annum.
Servicing an Audi A4 at an independent specialist will save you a good chunk of money over an official Audi dealer. Maintenance comes every 9000 miles, which is shorter than some rivals’ intervals, but it does mean your Audi A4 will be better looked after in the long term to prolong its life.

Audi wasn’t shy when it came to equipping the saloon, so even the standard Audi A4 model came with alloy wheels, electrically adjusted door mirrors, climate control, electric windows, electronic parking brake and a decent stereo.
The Audi A4 SE model that was very popular gained a 10-speaker stereo system, tri-zone climate control, rear parking sensors, cruise control and automatic headlights and wipers.
If you chose the Audi A4 S line, it came with a sportier look and 18-inch alloy wheels. It also had its suspension lowered by 20mm to give a firmer ride, though this could be deleted as a no-cost option. Also included with the S line were sporty trim details and LED rear lights.

New S line sports specification available from Feb 2008 for all versions of the A4 Saloon at a premium of £2,500 over the SE model in each case. Identifiable by LED strip daytime running lights, S line suspension including 30mm ride height reduction, 18-inch alloy wheels, body and interior upgrades. S line launch coincides with introduction of new lead-in 120PS 1.8 TFSI petrol engine available in conjunction with standard, SE and S line trim levels
Not to be confused with the 1.8-litre Turbo engine that has powered everything from the TT to the A6 in the past, the unit that had so far appeared in the A3 and new A4 in 160PS form is completely new. In its latest 120PS configuration it benefits from the same combination of turbo charging and FSI direct petrol injection for keen response and impressive overall efficiency, which is evidenced in the A4 1.8 TFSI (120PS) by a 0-60mph time of 10.2 seconds, a top speed of 130mph and 39.8mpg combined economy, delivered with a modest 169g/km CO2 output.
The new 120PS engine is available exclusively in conjunction with a six-speed manual gearbox, but for drivers who prefer the convenience of an automatic, the unique-in-class multitronic continuously variable transmission (CVT) has also just opened for order in the new A4 in conjunction with the 160PS version of the 1.8 TFSI engine.
Multitronic maintains the same 8.3-second 0-60mph time and 140mph top speed as the manual A4 1.8 TFSI (160PS). Unusually by automatic transmission standards, the 37.2 mpg combined consumption figure and 179g/km CO2 output it achieves also run the manual version impressively close (39.8mpg, 169g/km).
The A4 1.8 TFSI (120PS) is the first A4 model to be offered in standard specification. In addition to range-wide benefits normally associated with the executive class, such as a space-liberating electromechanical parking brake, intelligent key access and an auto-opening boot lid, it includes 16-inch alloy wheels, an 80-watt audio system with single CD drive and 6.5-inch display, electronic climate control, front and rear electric windows and a split/fold
rear seat.
Latest seven-speed S tronic twin-clutch transmission available with longitudinal engines from late 2008. Where existing six-speed S tronic was limited to the transversely mounted units in TT and A3, the latest transmission with 550Nm torque threshold can technically be fitted to new A4, A5, Q5 and more models in the future.

May 2009
Audi S4 unveiled
Innovative new rear axle for quattro system transforms handling responses by enabling variable torque distribution not only between front and rear axles but also between the rear wheels. Sport differential to be offered initially for the S4 (Saloon £34,260 OTR, Avant £35,600 OTR) as an optional element of the Audi drive select system, but will be rolled out for further models.
With its new active sport differential, Audi elevates the road dynamics of the new S4 quattro. A unique electronic regulating system distributes torque from the engine in continuously variable proportions left and right between the rear wheels, the resulting controlled power flow enabling the car to take corners even more responsively, and to retain its directional stability for considerably longer. With its help the potential for adjustment of the cornering line is much increased and understeer effectively becomes a thing of the past.
Six advances combine to create Audi S4 dynamics. The longer wheelbase of the latest A4 range and its forward mounted axle are the first and second elements, and help to establish the well-balanced basis of the chassis layout. Thirdly, a more advanced 40:60(front/rear) power distribution via quattro contributes to handling poise. For the fourth stage Audi then adds its unique and advanced drive select system enabling the driver to select comfort-oriented or more dynamic settings influencing throttle, steering and suspension response to suit widely varying individual preferences. The most notable advance within drive select is the ability to increase effective steering rack speed.
The 7-speed double clutch S tronic gearbox configured especially for longitudinal or ‘north - south’ application is the fifth key ingredient. This rapid acting, highly-efficient transmission is equipped with shift paddles and reacts responsively in its close interaction with the engine. Downshifts for example generate an automatic ‘blip’ of the throttle.
Finally, the sixth advance is the integration of the sport rear axle for the quattro permanent four-wheel-drive system. Taken to extremes normally reserved for the race circuit it readily allows the driver to create over steer in a controlled way, but its influence over agility and adjustability can be felt throughout the speed range, with the help of the car’s ESP stability control system which has been reconfigured to intervene later to allow maximum exploitation.
With the new sport differential influencing drive to the rear wheels, the S4 exhibits exceptional traction and stability. Close to the car’s handling limits, it acts like ESP, but with the principle reversed: corrective movements are not initiated solely by altering the engine settings or applying the brakes, but also by controlled redistribution of tractive force. As a result the car’s progress is distinctly smoother and more free-flowing, since ESP comes into action much less frequently.
Since its reaction time is extremely short – less than 100 milliseconds – the sport differential takes effect even more rapidly than ESP. Furthermore, ESP can only react to a discrepancy between the car’s steering angle and its actual body rotation (yaw), whereas the sport differential influences the car’s dynamic behaviour before any such discrepancies occur.
Depending on steering angle, lateral acceleration, yaw angle, road speed and other signals, the car’s control unit calculates the most suitable distribution of torque to the wheels for every driving situation. When the steering wheel is turned, for example, or the car accelerated in a corner, power is redirected in a controlled manner to the outer rear wheel. This has the effect of “forcing” the car into the corner so that the angle of the front wheels is followed accurately. The difference in tractive force between the left and right rear wheels also exerts a steering effect, so that the usual steering corrections by the driver are no longer needed. As a result understeer, or the tendency for the car to run wide at the front, is to all intents and purposes eliminated.
Buttons on the centre console enable drivers to vary the operating parameters of the sport differential as part of the Audi drive select adaptive dynamics system in three stages. In the ‘comfort’ mode, driving safety and the car’s stability have absolute priority, with optimal damping of load reversals. In the ‘auto’ mode the program calculates the best possible balance between all the functions. Finally, the ‘dynamic’ mode emphasises the functions contributing to maximum agility, so that the action of the sport differential is most easily felt. In this case, response to load reversals is both agile and easily controllable.
The drive select system also enables the driver to determine the engine’s throttle response characteristics, the feel of the servotronic speed-dependent power steering and the shift points selected by the S tronic transmission, where fitted.
Audi drive select with the sport differential can also be combined with electronic damping control. The gas-filled hydraulic shock absorbers have an additional valve with a continuous opening action. At a cycle frequency of 1000 per second, the control unit computes the optimal damping force. The electromagnetically controlled valve selects a damping characteristic to match the current driving situation at any given moment. Higher damping force may be needed to resist body movement when cornering rapidly or braking, whereas a lower damping force will be appropriate on potholed roads and a moderate setting on poor country roads.
The dynamic steering system uses a superimposed zero-play transmission to vary the effective steering ratio according to road speed. The extremely light, compact and torsionally rigid axial transmission is integrated into the steering column and combined with an electric motor. It operates without any play and is therefore extremely precise, varying its ratio by almost 100 per cent depending on road speed and the drive select mode chosen. When the car is being parked, the steering is extremely direct, whereas when driving in a straight line at high motorway speeds a more indirect steering ratio and reduced power assistance help to optimise the car’s directional stability.
S4's 3.0-litre, V6 power unit produces 333PS thanks to a supercharger generating a "seamless flow of power" from 440Nm of torque. This new V6 replaced the V8 engine of the previous S4 and delivers a 26 per cent cut in fuel consumption and CO2 without any penalty in performance. 0-60mph in 5.1 seconds. Advanced fuelling system uses FSI direct injection combined with Audi valve lift technology to create one of the most efficient high performance engines of its kind.
July 2009
New A4 2.0 TDIe combines 61.4mpg and 120g CO2 output with strong performance from 136PS common rail diesel. Start-stop and energy recuperation systems. Priced from £23,340 OTR. A4 2.0 TDIe six-speed manual - 136PS @ 4,200rpm, 320Nm @ 1,750-2,500rpm, 0-62mph in 9.5 seconds, top speed 143mph. Supplements 2.0-litre TDI range that already includes 120PS, 143PS and 170PS options.
August 2009
Audi A4 3.0 TDI clean diesel quattro. The A4 3.0 TDI clean diesel quattro already complies with the emission limits of the EU's Euro 6 standard, expected to become law in 2014. It is also very fuel-efficient, with the potential to cover up to 42.1mpg (Avant: 41.5mpg). And this TDI engine is indeed a powerful performer, needing only 6.2 seconds (Avant: 6.3 seconds) to go from zero to 62mph. Top speed is electronically governed to 155mph. In conjunction with a six-speed tiptronic and quattro permanent all-wheel drive, this vehicle guarantees a high degree of comfort and superior traction.
October 2011
Revised A4 announced
The new look accentuates the horizontal lines at the front end. The engine hood is more arched, the upper corners of the single frame grille are tapered, and the cross ribs and the Audi rings are highlighted three-dimensionally. The grille is painted grey, with high-gloss black on the six-cylinder models or in combination with the S line exterior package. The redesigned bumpers have angular air inlets, revised grilles and flat front fog lights. The A4 allroad quattro has horizontal chrome applications to the grille and round fog lights.
The headlights now have a slight wave at the bottom edges, and a re-arranged interior. Xenon plus headlights are available as optional equipment or standard on S line models. The LED daytime running lights form a narrow, optically continuous band that remains open in the vicinity of the xenon lens. The adaptive light, together with dynamic and static cornering lights, are available as an option.
The tail lights reflect the shape of the headlights, and in combination with Xenon plus have strips of LEDs. The bumper with its diffuser insert has been redesigned, with the exhaust system always terminating in two tailpipes.
The Saloon and the Avant offer the S line exterior package, while the Avant also includes a roof spoiler.
The A4 Saloon and the Avant each have a length of 4.70 metres(15.42 ft), while the A4 allroad quattro and the S4 are 4.72 metres(15.49 ft)long. The wheelbases for all models are 2.81 metres(9.22 ft), and the width is 1.83 and 1.84 metres, respectively(6.0 and 6.04 ft). The height varies between 1.41 and 1.50 metres(4.63 and 4.92 ft)depending on the body version.
Interiors have also been refined. New steering wheels with chrome and high-gloss inlays, with the leather sport steering wheel also featuring a flattened lower rim. The steering arm and the ignition key have been modified. High-gloss applications and the slender chrome trim at the controls add elegance to the interior.
The MMI navigation plus system now features four instead of eight buttons, with a shift function integrated in the volume control dial. Other improvements concern operation of the automatic transmission, the efficient air conditioning systems, Audi drive select and the multifunction steering wheel. The seat heating and air conditioning are now directly operated at the respective buttons.
All interior colours – except black – have been re-coordinated. The upholstery range has also been revised, with Fine Nappa leather replacing Valcona leather. The new, single-part cluster trim has been adapted in colour to the interior, while the inlays are available in Aluminium Trigon, walnut dark brown and fine grain ash natural. Especially eye-catching is the Beaufort oak plywood inlay.
The interior of the S line sport package comes in black. 18-inch wheels or the optional 19-inch wheels and Sport suspension that lowers the body by 20 millimetres complete the package. S line sport suspension, which lowers the body by a further 10 millimetres, is also available as a no-cost option on S line models. Audi exclusive and Audi exclusive line offer further individualised options.
The A4 Saloon’s luggage compartment retains is 480-litre capacity – 962 litres with the rear seats folded down. The A4 Avant and the A4 allroad quattro have 490 and 1,430 litres, respectively, with Audi offering an optional electrically-operated tailgate for both models.
Fuel consumption levels have dropped by 11 percent on average, despite increased power and torque of many of the engines. In the UK, Audi will offer a choice of five diesel and four petrol engines for both the Saloon and the Avant. All engines are supercharged direct-injection systems; the start-stop system and the recuperation system are standard throughout.
The EA189TDI engines are replaced by the EA288. These engines combine pulling power with pioneering efficiency, with the four-cylinder versions presenting extensive modifications. A new centrifugal pendulum-type absorber (in the 2.0 TDI with 136PS, 163PS or 177PS with quattro drive) in the dual-mass flywheel makes engine running even more refined and quieter at low revs, for even earlier upshifting and better fuel efficiency.
The most economical variant in the model family is the Audi A4 2.0 TDI with 136PS. In the Saloon, this engine helps the car achieve 67.3mpg on the combined cycle – a CO 2 equivalent of just 112 grams per km. The new A4 2.0 TDI with 163PS, also optimised for maximum efficiency, achieves 64.2mpg. This equates to 115 grams CO 2 per km. Both engines are available for the Saloon and the Avant.
In addition, two other four-cylinder diesel engines are available – with 143PS and 177PS. They can also be ordered for the allroad quattro, apart from the entry-level version. Three V6 TDI units complete the line. The 3.0 TDI with 204PS (not for the allroad quattro) is the most efficient six-cylinder engine in its class worldwide; in the A4 Saloon it helps the car achieve 57.6mpg on the combined cycle. The second variant, the 3.0 TDI, generates 245PS.
The A4 series also presents the latest state of the art in petrol engine technology. A new highlight of the TFSI family is the new 1.8-litre engine, available for the Saloon and the Avant. The four-cylinder engine delivers sporty thrust, with a power output of 170PS and 320 Nm (236.02 lb-ft)of torque, and impressive economy figures of 50.4mpg and 134 grams CO 2 per km. That is an efficiency improvement of 19 percent compared with the predecessor engine.
The new 1.8 TFSI engine features many innovations: in the control of its valves and their lift, in the novel thermal management system, in the fuel injection system, in the turbocharger and in the integration of the exhaust manifold in the cylinder head. The engine weighs 3.5 kilograms less and its internal friction has sharply decreased.
The entry-level petrol engine is the 1.8 TFSI with 120PS. The 2.0 TFSI – as the only spark-ignition engine also available in the A4 allroad quattro – delivers 211PS. At the top of the line is the 3.0 TFSI in the sporty S4, which develops an impressive 333PS.
The wide range of drivetrains is typical of Audi. A six-speed manual transmission is standard on the Saloon and Avant models with front-wheel drive; most variants offer continuously variable multitronic as an option. The quattro versions have either the manual transmission or the seven-speed S tronic on board. The A4 allroad quattro employs a manual transmission or S tronic with all engine versions.
A thermal management system shortens the warm-up phase of the manual transmission, among other things, and thereby reduces friction loss. All transmissions are distinguished by convenient and precise operation, high efficiency and a wide spread of gear ratios – the long ratios in the higher gears reduces fuel consumption, while the short ratios in the lower gears benefit the dynamics.
Quattro permanent all-wheel drive is standard on the A4 allroad quattro, and available in the Saloon and Avant from the 2.0 TDI with 177PS. The A4 family uses the self-locking centre differential here. In regular driving operation it primarily transmits the engine torque to the rear wheels in the ratio of 40 to 60. If necessary, redistribution occurs within the shortest possible time. The torque vectoring function supplements the work of the centre differential with finely incremented brake applications, to make handling even more precise and safer.
In the V6 quattro Audi offers the sport differential as a supplement, lending maximum precision and high traction to the A4 when cornering at the handling limits. The high-end component actively distributes the power between the rear wheels as required.
The chassis of the A4 offers sporty precision, high ride comfort and superior safety. The mounts of the rear suspension control arms and the characteristics of the shock absorbers have been even more finely tuned. Most of the components of the five-link front suspension and the trapezoidal-link rear suspension are made of aluminium.
Electromechanical power steering is new. The direct gear ratios convey precise road contact; slight brake applications counteract pulling to the side on unevenly slippery surfaces. The power steering requires no energy for straight-ahead motion, thereby reducing fuel consumption. This is equivalent to a reduction inemissions of up to 7 g/km.
June 2013
SE Technik specification has became more comprehensive, and more cost effective. At the same time, a number of the most popular engines in the A4 range that can be paired with it have also made valuable power and efficiency gains.
Available for all A4 Saloon and Avant models equipped with a four-cylinder engine, the SE Technik specification takes the more familiar SE trim level as its foundation. To this, it has until now added Milano leather upholstery, hard disk-based MMI navigation plus, Audi Music Interface (AMI) iPod connection and the Audi parking system plus with front and rear visual and acoustic guidance. Now, it also brings an exterior upgrade to 18-inch, ten-spoke ‘exclusive design’ alloy wheels (from 17-inch five-spoke wheels), and includes metallic paint.
The newly enhanced option carries a revised premium of £1,000 – a reduction of £350 from the original price, despite the increase in equipment. As a result, the SE Technik option represents a customer saving of £3,025 compared with the cost of specifying the various items individually.
The underlying SE specification for the A4 is far from minimalist as well. It includes three-zone climate control, cruise control, a Bluetooth phone interface, the Audi Concert audio system incorporating digital radio reception linked to a 6.5-inch colour display, sensors for headlights, wipers and reverse parking and split/folding rear seats. Avant models also feature powered tailgate operation.
It is possible to combine SE Technik specification with a choice of three turbo charged petrol units and three TDI diesels in the A4 Saloon and Avant range. The petrol line-up includes 120PS and 170PS versions of the 1.8-litre TFSI, and the 2.0-litre TFSI, which has just received a power boost from 211PS to 225PS. Like the 1.8-litre TFSI 170PS, this unit has benefited from revisions which enable it to comply with forthcoming 2014 EU6 emissions limits.
The A4 2.0 TFSI quattro S tronic which uses the upgraded 2.0-litre engine has a slightly reduced 0-62mph acceleration time of 6.4 seconds, down from 6.5, and a top speed increase from 152mph to an electronically limited 155mph. And despite the upturn, its CO2 output falls from 159g/km to 155g/km and its combined fuel economy is boosted from 40.4mpg to 42.2mpg.
Three versions of the perennially popular 2.0-litre TDI engine are available for diesel devotees – the 143PS unit has just been boosted to 150PS, and is topped and tailed by 136PS and 177PS options, the former powering the acutely economy focused A4 2.0 TDIe. To avoid impacting on this version’s optimal efficiency, SE Technik models equipped with this particular engine will feature 17-inch alloy wheels with low rolling resistance tyres.
SE Technik specification includes (in addition to SE):
- Milano leather upholstery
- HDD navigation
- Audi Music Interface
- Audi Parking Plus
- 18-inch 10-spoke design alloy wheels (new for 2014 MY, but excluding 2.0-litre TDIe engine)
- Metallic paint (new for 2014 MY)
March 2014
Audi A4 TDI Ultra launched
Although it shares its 163PS output with the more powerful of the two TDIe engines, the unit powering the latest ultra models is a completely new development engineered for even leaner burning with no impact on performance.
Peak power arrives 1,200rpm earlier at 3,000rpm in the new ultra engine, and maximum torque increases from 380Nm to 400Nm and is available over a wider spread from 1,750rpm to 2,750rpm. Acceleration from rest to 62mph in the exclusively six-speed manual-equipped A4 TDI Ultra is very slightly improved at 8.3 seconds and top speed holds firm at 140mph.
Up to 56.5mpg is possible according to the combined cycle test, delivered with CO2emissions of just 109g/km. Ultra badging at the rear discreetly marks out the A4 Ultra and it can be upgraded to SE Technik specification. A4 SE equipment includes 17-inch alloy wheels, an Audi Concert CD audio system incorporating DAB digital radio and linked to a 6.5-inch colour monitor, light and rain sensors, rear parking sensors and electronic climate control. A5 SE models also feature Milano leather upholstery.
SE Technik specification for the A4 adds Milano leather upholstery, along with additional features such as hard disk-based MMI Navigation plus, Audi Music Interface (AMI) iPod connection and the Audi Parking System Plus with front and rear sensors.
All A4 ultra models are equipped as standard with lowered sports suspension to reduce drag and maximise economy, and for the same reason the 18-inch alloy wheels normally included as part of the SE Technik upgrade for A4 models are omitted.
What to watch out for
Multitronic models built before third week of March 2008 may not have the correct chips fitted to the transmission, cooling and charging system, so that the ECU cannot accept recoding when a towbar is retro-fitted (meaning that trailer stability control, etc cannot be engaged and potentially breaking warranty if used to tow). Audi UK is aware of this problem (but does not appear to have told its dealers) and offered one reader £1,500 towards the £3,000 cost of replacements (took three days to fit) as long as the towbar was fitted by an Audi dealer. The reader's dealer met a proportion of the remainder as the car was sold to him as suitable for towing. Can be a serious problem if having towbar retro-fitted outside dealer network.
14-03-2011:3.0 TDI quattro prone to water pump failure and also prone to losing coolant from the water cooled EGR valve.
11-05-2011:Apparent "design fault" with 2 litre (petrol) engines that leads to excessive oil consumption. One reader's 6 month old, 4,000 mile A5 2.0 petrol taken in for "modification". New Audi 2.0 petrol engines already have this "modification".
28-03-2012:DMF problems starting to emerge on manual 2.0 TDI 170 where clutches are lifted at idle revs.
20-07-2012:Sporadic reports of high oil consumption of chain cam 1.8 TFSI and 2.0 TFSI engines. Apparently Audi considers 1,000 miles a litre to be "normal" oil consumption for these engines. The reason is probably filling the engines with synthetic oil on the production line and owners not revving the engines sufficiently to bed in the oil rings.
25-08-2012:On the 2.0TDI 143 Multitronic, a combination of Multitronic and slow running torque engine plus the complex drive train route leaves the power steering pump at low pressure at some times and can cause a vibration. Best not to use too much steering lock at low speeds.
08-02-2013:Multitronic transmission failed at 2 years 10 months. Replaced under warranty.
21-02-2013:Non-availability of mud-flaps for the enhanced S Line body shape continues and is a known issue to many, many, Audi drivers but being ignored by Audi themselves.
The out-of-date sat-nav system remains an issue and cannot be resolved.
21-02-2013:Failure reported of the Emission Control System of a TDI S Line which was repaired by Audi Assist through the correct alignment of the exhaust gas pipe where it enters the pipe from the intercooler - a known problem according to the fitter covered by an Audi repair sheet on a number of A4 S-line vehicles. This did seriously and adversely affect the performance of the car as the electrically-controlled valve became heavily blocked with emission gas residue.
16-05-2013:Seems to be a problem with turbo oil seals on 2.0 TDI 143 which, in extreme cases, can send so much lube oil into the combustion chamber that the pistons can hydraulic. So the warning is to idle those turbos before switching off from hot. This came from an Audi dealer who also reported frequent 1.8 and 2.0 TFSI engine failures, but gave no detail.
30-08-2013:T urbo failure on 21 month old 25k mile 2.0 TDI. Turbo, exhaust and DPF replaced under warranty. Stop/start system thought to be the culprit.
01-09-2013:£250 waterpump failure on chain cam 95k mile 2009 A4 2.7 TDI Multitronic, closely followed by failure of EGR cooler at £1,200, but Audi offered 70% of parts price.
21-10-2013:Water leaks onto the driver's and front passenger's feet may be due to faulty bulkhead cable seals. Can affect the ECU. Audi dealers will normally fix this under warranty or goodwill.
05-12-2013:Clutch/DMF failed on 2011 Audi A4 at 20,000 kilometres.

31-08-2017:Report of front offside wheel bearing failing on 2014 Audi A4 B8 at 36,000 miles. Dealer made the owner pay for its replacement.
23-01-2018:Audi has ordered by German Federal Motor Transport Agency (KBA) to recall 127,000 cars following the alleged discovery of emissions cheat devices. Affects Audi A4, A5, A6, A7, Q5, SQ5 and Q7 cars fitted with V6TDI diesel engines. According to German newspaper Bild am Sontag (BaS), KBA ordered these vehicles be recalled after detecting “unacceptable shut-off decides” on several new V6 diesel engines which meet current EU6 emissions standards.
28-02-2018:Report of MMI system of 2014 Audi A4 failing in October 2017 at 14,000 miles: the screen is blank and there are no lights on the controls. Owner took the car back to the dealer and after several hours of diagnosis he was told that the '5F' unit had failed (apparently this is the main controller for the MMI that communicates with the sat nav/radio etc) and it would cost £3,500 to replace. Audi is offering no goodwill gesture, so owner is stuck with a non functioning MMI. Fortunately it doesn't really affect the use of the car because heating and ventilation controls are separate.
25-07-2018:'Emission Control System' indicator lamp came on in 2014 Audi A4 B8 2.0TDI at 40,500 miles. No change in power or fuel economy. Owner took it to Bosch specialist that services it and they carried out a forced DPF regeneration. Light came back on three weeks later whilst travelling on the motorway having completed about 40 miles on that particular journey at approx 70mph. Garage then carried out diagnostics again and fitted a new exhaust sensor, brought it back but didn't seem sure the problem was fixed. Three days later light came on again. This time garage checked the AdBlue manually and said it was down to 2 litres and was causing the problem (had been topped up with 10 litres four months earlier and inany case the warning light normally comes on to warn when it's low). Two journeys later, the light has come on whilst travelling at 60-70 mph. Again, there is no change in performance. We think that the DPF is not actively regenerating using post-injected diesel. Something wrong with that part of the system.
10-08-2018:After TSB replacement of auxiliary heater element of 2013 Audi A4 B8, coolant pump failed to siwtch off and flattened the car's battery. Audi dealer said nothing to do with the TSB. Independent garage begged to differ.
27-09-2018:Problem with 2014 Audi A4 B8 2.0TDI Teknik at 42,000 miles. Car had been back to Audi dealer a month before problem with the emission light started. It was recalled for the Audi auxillary heater issue. Owner's, my Bosch specialist checked the car's records and found that an ECU reflash was carried out by Audi at the same time. (EA189 NOx emissions fix.) Once 'emission control system' indicator lamp came on there was no change in power or anything else and the car drove as usual. Owner took car to Bosch specialist garage who has maintained it from new. It has now been back five times in an attempt to rectify the problem. Each time the light returns after a couple of weeks or so, usually after/during driving on motorways or A roads. The work carried out so far is: 1. Forced regeneration; 2. Exhaust oxygen sensor replaced; 3. Adblue refilled; 4. Oil - some syphoned off as dipstick showing different measurement to engine management system which may have prevented regeneration; 5. Air filter replaced, forced regeneration. Emission light description in Audi manual: "If the indicator lamp lights up or flashes, a malfunction has occurred which can reduce the quality of the exhaust gas and damage the catalytic converter. Drive slowly to a qualified workshop without delay and have the fault rectified."
29-11-2018:Report of failure of dual mass flywheel of 2009 Audi A4 2.0TSI and also failure of the piston rings that resulted in oil consumption of 1 litre per 250 miles.

17-12-2018:Report of very high oil consumption of 2010 Audi A4 B8 avant with EA888 2.0TSI engine.
15-06-2019:Report of catalogue of disaster with 2013/62 Audi A4 Avant S-Line 1.8TFSI, engine code CJE030161. On 21st May 2018 car would not start. AA called and got it going. 22nd May again car would not start again, at 39,900 miles. AA towed to Audi dealer. Audi dealer did an analysis and discovered that the N488 coolant regulator had failed and had tracked to the V50 coolant pump, back up the wiring loom and to the engine ECU. Owner quoted £4,085.58 to effect a repair but was warned that further damage may be found once they were able to start the vehicle. This proved to be the case because it was then discovered that the parking brake control unit needed to be replaced. The total job cost £4,588.24. Owner then discovered that failure of the N488 on the A8, had been the reason for a safety recall for that model in the USA and Canada (Safety Recall Code 80B9.). Despite this, Audi UK refused any goodwill.
03-07-2019:Report of "rolling sensation" at speed in 2014 Audi A4 1.8TFSI CVT. Suspect failing dampers.
11-10-2019:2.0TDI PD oil pump drive issue explained by cphaza on audi-sport.net<<The problem with the 2.0 PD engine is the drive from the slave balancer shaft to the oil pump, which is a piece of 6 AF hex bar which has inadequate engagement depth with the grooves in the slave shaft. It's the torsional oscillations caused by the balance shafts which destroy the oil pump coupling (the 6mm AF bit of hex) and the chain drive to the balancer shafts before the gear driven systems came out, though these still give problems with the hex key rounding. Think washing machine -> unbalanced load -> keep doing it = new machine. The problem is with lack of concentricity of the drive socket into which the drive rod/hex fits. The drive socket is can be off centre by at least 0.1mm. In engineering terms, this is a massive defect. All the drive sockets in the failed units were off centre, but all the replacement balancer units were dead centre and have not led to a repeat failure. Some replacement balancer units have now done 100k+ miles according to some garages. You will get this problem at some point if you have a 2.0TDi WITH balancer shafts. If your 2.0TDi does NOT have balancer shafts, you will be ok. If you fit the latest balancer shaft/ pump assembly from VAG it will more than likely cure the problem for life as they have made the hex longer and centered it all properly.>>
24-10-2019:Report of EGR of 2012 Audi A4 B8 2.0TDI failing more than two years after the EA189 NOx emissions fix, so outside the 'Rebulding Trust' consequential damage warranty. Owner quoted £650 to replace.
15-11-2019:Report of clutch judder from 24k mile 2015 Audi A4 B8 1.8 TFSI 170PS manual recently purchased from Audi dealer. At slow in-town stop start speeds there is a judder when moving off in 1st gear at low rpm of 1,000 - 1,400 rpm. Sometimes it can appear as if the clutch snatches. However, if brought to around 2,000 rpm before releasing the clutch, the car moves off smoothly. Owner had clutch assessed at a different Audi dealer who pronouced it okay.
