Audi A6 (2011 – 2018) At A Glance
Impressive cabin with a straightforward layout. Very quiet and refined on the move. Navigation and leather seats in all models. Efficient 2.0 TDI provides good performance.
Not quite on a par with a BMW 5 Series for driver involvement.
Audi knocked it out of the park when it launched the Audi A6 in 2011. It mixed much of the style and ability of the larger Audi A8 with a more wieldy, better to drive and more compact body. There was still a huge amount of cabin space, and it was far better to drive than previous generations, even if it wasn’t quite as sharp in its responses as the BMW 5 Series. Read on for our full Audi A6 review.
The new Audi A6 saloon of 2011 was completely revamped to present an up to the minute alternative to other premium saloons such as the BMW 5 Series, Mercedes E-Class and Britain’s own Jaguar XF.
It certainly looks good and has a far sleeker and sharper design than before. It doesn’t break too many boundaries, but then most people who buy these posh saloons don’t necessarily want to be noticed. Discreet but stylish is where it’s at.
There’s a hint of Audi A8 in the styling and this continues inside, where the layout has a modern and minimalist design with great attention to detail and a quality feel throughout. It’s a car that you could happily spend many an hour in.
It’s just as impressive on the road with superb refinement, ride comfort and very little noise. And then there’s economy.
The 2.0 TDI model can average more than 64mpg in some versions. That’s according to the claimed figures of course, but in real life you’ll probably see 50mpg, which isn’t at all bad for a big saloon.
It doesn’t hang around either, and has plenty of torque giving a great turn of pace.
It’s so good, it’s right up there alongside the contemporary BMW 5 Series, and while it may not quite match the BMW on some fronts, it trumps it on specification thanks to a very high level of standard equipment that includes leather upholstery, cruise control, Bluetooth and navigation.

Audi A6 (2011 – 2018) handling and engines
- Engines range from 1.8 TFSI 190 S tronic to 3.0 TFSI quattro
- Readers report Real MPG to be between 18–58 mpg
Audi A6 (2011 – 2018): Handling and ride quality
The car the Audi A6 is always compared with is the BMW 5 Series. The big difference is that the BMW 5 Series is rear-wheel drive, whereas the standard Audi A6 is front-wheel drive.
With such smooth power deliveries from the Audi A6’s engines, the difference is not as pronounced as you’d expect. And most models come with a quattro version, which helps with traction in the wet, plus of course when it snows – as long as you have the right tyres on.
On many occasions, knowing that all four wheels have traction gives you confidence in situations where a rear-wheel drive car would struggle.
In fact the Audi A6 handles very well considering this is a sizeable saloon that’s not far off five metres long.
Much of that is down to its low weight. At 1575kg (for the 2.0 TDI) it is considerably lighter than diesel alternatives such as the BMW 5 Series and Mercedes E-Class, which tip the scales at more than 1700kg. That difference is the equivalent of carrying around two grown men in the back.
This helps it feel nimble and precise on the road, with impressive body control in bends or when accelerating and braking hard. The slight disappointment is the steering.
Audi has made a lot of noise about this Audi A6 having more driver involvement, but the new electromechanical steering feels detached and could do with more weight.
It’s still direct and responsive, but doesn’t feel as involving as a BMW 5 Series. However, in normal everyday driving, it’s really not that much of an issue, so most drivers are unlikely to notice.
What does stand out is the supremely comfortable ride. It’s been a criticism of Audi models in the past, especially the sporty S line models, but this Audi A6 has no such issues.
It’s quiet, forgiving and is just as happy over potholed city streets as it is on bumpy and uneven country roads. This makes the interior a very serene place to be, whether you’re driving or one of the passengers.
Audi A6 (2011 – 2018): Engines
The Audi A6 was offered with a broad selection of motors during its seven-year run.
Most common is the 2.0-litre turbodiesel that came with power outputs of 177PS to the end of 2014, and then 190PS for the remainder of this Audi A6’s lifespan.
The more powerful version came with the option of Quattro all-wheel drive and also in Ultra efficiency form that offered up to 65.7mpg, while still delivering 0-62mph in 7.9 seconds. It’s arguably the pick of the bunch.
There have been two 3.0-litre V6 turbodiesels, the first with anything from 218PS all the way up to 272PS and with front or four-wheel drive depending on model. From 2015, Audi offered the twin-turbo 3.0 V6 with a healthy 320PS and Quattro as standard.
Don’t overlook the petrol engines in this Audi A6. The 1.8 TFSI is a bit underwhelming but smooth, while the 2.0 TFSI has plenty of get up and go thanks to 252PS.
There was also a hybrid-powered 2.0 with 245PS that makes more sense now than it did when new. The ultimate petrol engine in the mainstream Audi A6 line-up is the 3.0 TFSI V6 that produces 300PS for 0-62mph in 5.5 seconds.
Most Audi A6 models use the seven-speed S tronic semi-automatic gearbox, which is ideally suited to the car.
There was also a six-speed manual for the less powerful petrol and diesel engines, plus the Multitronic continuously variable transmission that is something of an acquired taste, so try before you buy.
Audi A6 (2011 – 2018): Safety
Front, side and curtain airbags are all standard on the Audi A6 saloon, along with traction control, anti-lock brakes and Isofix child seat points in the two outer rear seats.
That was enough to earn the Audi A6 a five-star rating from Euro NCAP when new.
It also comes with front and rear parking sensors, automatic wipers and headlights, hill hold assist, and park assist. What you don’t get, though, due to the age of this model is automatic emergency braking or lane keep assist tech.
However, night vision and a head-up display were options when the car was new.
Audi A6 (2011 – 2018): Towing
Depending on which model of Audi A6 saloon you choose, it can tow a braked trailer with a maximum weight of between 1800 and 2100kg. The larger diesel-engined models with Quattro four-wheel drive are the best heavy haulers for those who want to pull a caravan. With an unbraked trailer, the maximum is 750kg.

Audi A6 (2011 – 2018): Practicality
Practicality is a strong point for the Audi A6. It has a large boot with a wide opening and with 530-litres of space is slightly bigger (by 10 litres) than the 5 Series it launched against.
There’s a split-folding rear seat as standard so you can carry longer items.
Passenger space in the back is good with plenty of headroom and kneespace, even for taller people, although the large central transmission tunnel means it’s a real squeeze with three there.
In the front, the Audi A6 has more than sufficient room for even the tallest driver and passenger. The seats adjust in several directions, along with the steering wheel’s two-way movement, so finding the ideal driving position is simple.
You’ll also find the seats among the most supportive and comfiest of any car you’ll ever sit in. All-round vision is good for the driver, and aided by front and rear parking sensors in all versions.
Audi A6 (2011 – 2018): Quality and finish
The interior of the Audi A6 draws on the design of the luxury Audi A8 and Audi A7 Sportback of the same period with similar switches, controls and instrument dials, which give it a more upmarket feel than the previous model.
As you’d expect from a car at this level, there’s a very solid and well-engineered feel to the interior, while the high centre console and slightly angled dash make it feel like it’s wrapped around you.
Thanks to a neat design and tactile materials, the Audi A6 is far more inviting than the austere E-Class, although it doesn’t have the charm of a Jaguar XF.
It’s very simple to get on with, though, and isn’t cluttered with too many buttons, despite all the on-board systems. That’s because most are controlled through the MMI (multi media interface) system via the dial next to the gear lever. It’s very intuitive and straightforward to use.
Impressively, the Audi A6 comes with sat nav as standard. It’s a good system and as it works off an SD card, is quick at calculating routes. The display is also nice and easy to understand.
It comes with dynamic route guidance which will take you around traffic, and includes Bluetooth so you can take calls on the move.
Audi A6 (2011 – 2018): Infotainment
In addition to the standard, and very good, MMI screen and rotary controller set-up, this generation of Audi A6 could be upgraded with MMI Navigation Plus as an optional extra with a larger eight-inch higher resolution screen along with a DVD drive, two card readers and 20GB of music storage.
It also used Audi’s MMI touch with Black Panel technology – one of Audi’s neatest features. It’s a clever touchpad that allows you to actually write out letters and numbers with your finger which the sat-nav will recognise, so you can spell out your destination without taking your eyes off the road.
Other new innovations included an optional head-up display similar to the system BMW introduced a few years before. This projects key data (such as fuel economy and speed) on to the windscreen so that it cleverly appears as if it’s floating around 2.5 metres ahead of the driver.
However, in a touch of one-upmanship, Audi developed a full colour display that also lets you know what the speed limit is thanks to a video camera in the rear view mirror that detects speed limit signs.
Audi A6 (2011 – 2018) value for money
Audi A6 (2011 – 2018): Prices
The 2.0-litre TDI turbodiesel version of this generation of Audi A6 is by far the most commonly found model, thanks to its appeal as a company car when new.
An early model with less than 80,000 miles on the clock could be yours from £8500 in S line trim.
Go for one of the last versions and prices are around the £18,000 mark for a car in great condition and with average mileage for its year.
Between this and the early cars, an updated model from 2015 with the efficient Ultra diesel will cost from around £12,000.
Audi A6 (2011 – 2018): Running Costs
The Audi A6 2.0 TDI Ultra model claimed up to 65.70 mpg official combined fuel economy. Even given this was assessed under the older economy tests, it’s still impressive and translates to a real-world 55mpg on a motorway run and around 50mpg in mixed driving.
That makes life bearable when running a large saloon, and its 113g/km of carbon dioxide emissions also helps keep costs down when it comes to road tax.
Insuring an Audi A6 saloon shouldn’t be too bank-busting as most sit at the lower end of the range. This stretches from group 27 to 44, with the upper end reserved for the most potent and larger-engined petrol versions.
You should reckon on servicing this generation of Audi A6 at 9000 to 18,000 mile intervals depending on use. It would also be wise to budget for a gearbox service on a used buy every 40,000 miles to keep the car humming along sweetly.

The saloon was offered with a familiar choice of trims, starting with the Audi A6 SE. With this, you got four-zone climate control, heated front seats, leather upholstery, electric windows all round and keyless ignition.
There were 17-inch alloy wheels, parking sensors both at the front and rear, automatic wipers and lights and cruise control.
The SE also features Bluetooth and sat-nav for the MMI infotainment screen that emerged from the dash on start-up. From late 2014, the Audi A6’s headlights were upgraded to Xenon items.
With the Audi A6 S line, you gained larger 18-inch alloy wheels and firmer, lowered suspension, while inside there were front sports seats. The S line also came with directional indicators as part of the late 2014 revisions. As with all Audi A6s, from 2012 on, there was an improved Bose stereo.
At the top of the tree sat the Audi A6 Black Edition, which came with 20-inch alloys and black-coloured trim details in place of the SE and S line’s chrome bits on the inside and out.

New Audi A6 unveiled
All new technology-laden Audi A6 executive saloon employs aluminium and steel composite construction to minimise weight. Derived from A7 Sportback. Open for ordering in the UK in January 2011, priced from £30,145 OTR (including 20% VAT) - first customer deliveries in spring 2011
4,920mm long, 1,870mm wide, 1,460mm high.
Composite aluminium and steel construction means 2.0 TDI model weighs just 1,575kg, 15% less than an all-steel equivalent. Exterior panels are 20% aluminium. Choice of four efficient engines at launch – one petrol and three diesel – teamed with manual, multitronic or S tronic transmissions. Multitronic CVT or manual for front-wheel drive, and S tronic twin clutch for quattro models
A6 2.0 TDI (177PS) manual is the most efficient derivative – 0-62mph in 8.7 seconds, top speed 142mph, emits 129g/km CO2 and certified at 57mpg combined. Options include head-up display, Bluetooth internet connection, 1,200-watt Bang & Olufsen Advanced Sound System and MMI touch with 3D graphics chip. A6 hybrid model to become available.
The 2.0-litre TDI 177PS, 3.0-litre TDI 204PS, 3.0-litre TDI 245PS and 3.0-litre TFSI 300PS units all make use of advanced direct injection technology for the leanest possible fuel burn rate, and work in conjunction with important technologies from the brand’s modular efficiency platform – the start-stop system, the energy recovery system and the innovative thermal management concept. As a result, fuel economy has improved by up to 19 per cent compared to the previous A6.
A6 hybrid will combine a 2.0-litre TFSI petrol engine with an electric motor will be capable of zero emission urban driving and up to 45.6mpg, yet will also have 245PS on tap for strong performance.
The quattro permanent all-wheel drive system fitted to the new A6 Saloon is the latest incarnation, with a crown gear centre differential and a torque-vectoring function for the ultimate in traction, stability and dynamic response. For the top-of-the-line engines, the quattro sport differential that has already won acclaim in performance cars such as the S4 will also be offered as an option.
New energy efficient electromechanical power steering, in conjunction with lightweight aluminium suspension. Standard fit Audi drive select adaptive dynamics system will allow drivers to fine-tune the car’s responses as desired via the MMI screen, and in front-wheel-drive models the latest Electronic Stability Programme with electronic limited slip differential will imperceptibly boost agility and subtly maintain order during challenging driving.
More refined ride than previous A6. Option of adaptive air suspension with controlled damping. Cocooning ‘wraparound’ dash panel and much roomier back seat than prefvious A6. Now a full 5 seater. Supportive seats upholstered as standard in Milano leather position occupants perfectly in relation to the cabin’s focal point, the Multi Media Interface with its 6.5-inch retractable monitor and large central control knob. MMI provides easy and intuitive access to the high quality audio system, the Bluetooth phone interface and the SD card-based navigation system is standard in the new Audi A6.
8-inch monitor and fingertip sensitive touch pad are available to upgrade MMI to MMI Touch. The system’s touch pad enables characters to be ‘drawn’ by the driver using an index finger for navigation or telephone data entry. As well as intelligent 3D navigation mapping, the new MMI Touch system can store audio tracks and telephone data on its sizeable hard disk.
Online services including news and weather information supplied by Google will also be accessible if the Mobile Telephone Preparation High option is specified. This option will enable drivers to plot detailed routes on a home computer and download them to the navigation system when they start a trip. Google Earth images will also be beamed via the car’s internal UMTS module to the MMI monitor for navigation purposes. Through its wireless local area network link passengers will also be able to connect to the internet using their own computers. It requires either a SIM card fitted to the system which then disables the driver's Bluetooth hands free connection to his own mobile, or requires pairing with the driver's mobile. The signals are not free.
MMI navigation plus will be able to work closely with the optional assistance and safety systems in the new A6. It can forward route data to the control units for the headlights, the automatic transmission and the adaptive cruise control with stop & go function. This will enable these systems to recognise complex scenarios and assist the driver. The Audi pre-sense basic system first seen in the new A8 will also provide further safety back-up by analysing the information from the ESP sensors and intervening to activate the hazard warning lights, close the side windows and sunroof and tension the seatbelts when maximum brake application or skidding is detected. The pre-sense system is expandable in various stages: the full version brakes the car automatically in order to minimise the consequences of a nose-to-tail collision.
Optional driver aids will also include a night vision assistant employing a thermal imaging camera to highlight ‘warm-blooded’ road users in front of the car, a head-up display projecting key information onto the windscreen so that it appears to float about 2.5 metres ahead and a park assist system which automatically takes care of the steering function for the driver when manoeuvring into parallel or perpendicular parking spaces. More familiar options such as the Audi side assist blind spot warning system and the Audi lane assist lane departure detection system will also be available.

January 2012
New 313PS Biturbo TDI engine is now available for A6 Saloon and Avant models. The new twin-turbo V6 is notable not only for being the most powerful six-cylinder diesel engine ever offered by the Vorsprung durch Technik brand, but also the sweetest-sounding. Available now in A6 models priced from £43,810 OTR, and from £51,645 OTR in the A7 Sportback, it combines trademark Audi TDI refinement with an exhaust-mounted sound actuator that enables it to deliver its mighty 650Nm output to the tune of a distinctly sporting soundtrack.
Slotting in above the single-turbo 204PS and 245PS versions of the 3.0 TDI that already feature in the A6 and A7 Sportback ranges, the latest V6 has a two-stage turbocharger group that delivers a maximum boost pressure of up to 3.2 bar, helping the A6 3.0 BiTDI quattro Saloon to lunge at the horizon and pass the 62mph marker in as little as 5.1 seconds, and the A6 Avant and A7 Sportback to do the same in just 5.3 seconds. An electronically limited top speed of 155mph is common to all versions.
Like the existing TDI engines, the new star performer is backed up by technologies from the Audi modular efficiency platform, including start-stop and recuperation systems and the innovative thermal management system that quickly brings the coolant and oil up to their operating temperatures. With their help, combined economy in A6 and A7 Sportback models is on an equal footing at 44.1mpg – an impressive figure given the high outputs and low acceleration times involved.
Thanks to an innovative actuator in the auxiliary channel of the exhaust system, the BiTDI A6 and A7 Sportback models don’t sound like they should be capable of such level-headed economy figures. The actuator system essentially consists of a speaker which imposes a defined oscillation pattern on the exhaust flow and transforms the typical TDI exhaust note into a more sonorous roar that is closer to the output of a high-performance petrol engine.
Without exception, power is transmitted from the BiTDI engine via an eight-speed tiptronic transmission to the latest generation quattro all-wheel-drive system, which features a self-locking centre differential and torque vectoring for optimum traction and stability. A sport differential which distributes power in continuously variable proportions between the rear wheels is available from the options list to sharpen and quicken response even further.
The mighty new BiTDI engine is available in conjunction with SE and S line specification in the A6 Saloon, A6 Avant and A7 Sportback. The forthcoming A6 allroad quattro, due to open for order in February, will also offer this exceptional unit.
Stand-out features common to all these models include satellite navigation linked to a 6.5-inch retractable colour monitor, Milano leather upholstery, the Audi drive select adaptive dynamics system controlling throttle response, transmission shift points and steering feel, the Audi parking system plus, light and rain sensors, cruise control and keyless go push-button engine ignition.

November 2012
Black Edition A6 introduced
Priced from £35,010 OTR to £49,185 OTR, Black Edition distinguishing features start from the ground up with rotor-design 20-inch alloy wheels with a dark titanium finish. These fill their arches in the A6 helped by lowered sports suspension which is a standard feature of the S line models on which the new specification is based.
There's a black finish for the grille and number plate surrounds and the window frame strips, and by privacy glass extending from the B-pillar rearwards. Inside, the scene is set by distinctive Piano Black inlays which complement the sports seats upholstered in black Valcona leather and the black headlining. The S line equipment list is also expanded by a BOSE surround sound system, DAB digital radio and the Audi Music Interface (AMI) for iPod connection.
The new Black Edition specification is an ideal accompaniment to the formidable 3.0-litre BiTDI unit with its 313PS and 650Nm of torque. It's also available the 177PS 2.0-litre TDI upwards and with either front-wheel-drive or quattro all-wheel-drive.
October 2013
A6 3.0 TDI quattro 204PS launched
Prices from £38,385 OTR and 0 to 62mph in seven seconds (7.2 seconds in the Avant). Benefits from a torque boost over its eight-speed multitronic transmission-equipped, front-wheel-drive equivalent, from 400Nm to 450Nm. Top speeds are 149mph for both Saloon options, and 143mph for both Avants.
Three V6 TDI options The new 204 PS V6 TDI quattro is one of three powerful V6 TDI engines in the A6 range to feature the crown gear centre differential-based version of the quattro all-wheel-drive system. The more powerful 3.0 V6 TDI engine with 245 PS and the top of the range 313 PS V6 BiTDI are linked to this system exclusively.
Prices for the new 204PS A6 3.0 TDI quattro models start from £38,385 for the A6 Saloon 3.0 TDI quattro SE, increasing to £44,945 for the lavishly equipped, S line-based A6 Avant 3.0 TDI quattro Black Edition.
February 2014
A6 TDI ultra introduced
A new range of Audi ‘ultra’ models focusing more intensively than ever before on class-leading economy and company car viability will be spearheaded in the UK by the new A6 ultra, which is available to order priced from £32,515 OTR.
Power for the Saloon and Avant-based A6 TDI ultra variants is provided by a new 2.0-litre diesel engine that supersedes the existing 177PS unit and complies with forthcoming EU6 emissions regulations. Power increases to 190PS and torque from 380Nm to 400Nm, the latter available over a wider spread from 1,750 to 3,000rpm.
At launch in the UK the new unit is linked exclusively to a completely redesigned seven-speed S tronic twin-clutch transmission, which replaces the eight-speed multitronic CVT in four-cylinder models. Advances in the new transmission include further minimised internal friction, highly efficient oil supply and a centrifugal pendulum-type absorber that counteracts undesirable vibrations and allows low-noise driving at very low engine speeds. Later in 2014, manual transmission versions will also become available.
Combined economy and emissions in the new A6 2.0 TDI ultra with the seven-speed S tronic transmission show the most impressive improvement, with up to 64.2mpg delivered along with CO2output of just 114g/km (2.0 TDI 177PS multitronic 56.5mpg, 132g/km).
Uniquely for a conventionally powered car in the premium sector – it has been achieved without need for any restriction on equipment. Like all A6 engines the new 190PS 2.0 TDI ultra unit can be paired with SE, S line and Black Edition specification, meaning its improved performance can be enjoyed along with alloy wheels of up to 20 inches in diameter, with the popular S line body styling additions and with every other infotainment feature, driver aid and comfort-enhancing option available for the rest of the range.
Subtle ‘ultra’ badging at the rear will mark out the most efficiency-focused A6 models, all of which will share the core A6 specification common to the range as a whole. This includes full leather upholstery, the MMI Radio Plus with 6.5-inch retractable colour display and DAB digital radio, SD card-based satellite navigation, light and rain sensors, cruise control, keyless go and the Audi parking system plus with acoustic and visual guidance.
September 2014
Audi A6 range revised
Orders taken September 2014 for delivery late 2014. Prices from £32,000.
Enhancements include: Styling revisions, xenon headlamps as standard for SE versions, LED headlights as standard for S line,Matrix LED lights optional for A6 and S6 and standard for RS 6 Avant; Interior decor improvements and upgraded infotainment system; EU6-compliant engine range benefits from emissions reductions of up to 22 per cent; Line-up includes 2.0 TDI ultra offering up to 64mpg with CO2 of as little as 114g/km; New S tronic twin-clutch transmission replaces multitronic CVT in front-wheel-drive variants.
There are upgraded infotainment options, which include new versions of the MMI navigation plus and Audi connect elements. Based around an eight-inch retractable colour monitor, MMI navigation plus is available as an alternative to the standard navigation system. It now uses a more powerful Tegra 30 graphics processor from Audi's partner Nvidia, and includes MMI touch, which enables the driver to scroll and zoom in lists and maps via a touchpad. Audi connect now brings tailored Internet-based services and new media streaming apps to the car via the latest LTE high‑speed data transmission standard for ultra-fast 4G click-through and download functionality.
Audi phone box option is also now available - it enables occupants to connect their mobile phones to the car‘s antenna for improved reception simply by placing them in the phone box compartment.
In the UK the engine line-up for the updated A6 and A6 Avant comprises four TDI engines with either four or six cylinders and either single or twin turbo charging. All engines comply with the limits of the Euro 6 emission standard, and their CO2emissions have been reduced by as much as 22 percent. As before, the most efficient engine - the 2.0-litre TDI four-cylinder with 190PS - is reserved for Ultra versions of the saloon and Avant which combine strong performance, hushed refinement and the potential to return up to 60mpg with CO2 output from as little as 114g/km. Despite its sports styling, 18-inch alloy wheels and extensive specification, even the A6 2.0 TDI ultra S line Saloon with S tronic transmission achieves these exceptional economy and emissions figures.
The trio of 3.0-litre six-cylinder TDI ‘clean diesel' units starts with a single-turbo V6 with 218PS which replaces the existing 204PS version, and is followed by a 272PS variant, also with a single charger, which takes over from the outgoing 245PS unit. At the top of the range, the 3.0 TDI clean diesel biturbo produces 320PS, an increase of 7PS over its existing equivalent.
The high‑performance diesel is paired with an eight‑speed tiptronic automatic transmission. All other engine variants are linked to either a newly designed six‑speed manual gearbox that is particularly lightweight and low-friction, or a seven‑speed S tronic twin-clutch transmission. In the versions with front-wheel drive, a fully redeveloped dual-clutch transmission replaces the familiar eight-speed multitronic continuously variable transmission.
Quattro all-wheel-drive is available in conjunction with all engines bar the 2.0-litre TDI, and in versions with 272PS and above, the quattro permanent all‑wheel drive system can be supplemented with the sport differential, which actively distributes power between the rear wheels.
Sports suspension lowered by 20mm is standard for the A6 S line and optional for the SE model, and the former can be rooted to the tarmac even more firmly by S line sports suspension which lowers the body by a further 10mm. Alternatively, the cushioned comfort of electronically controlled adaptive air suspension is available in conjunction with both specification options. The Audi drive select dynamic handling system is standard.
What to watch out for
Mysterious problem with three month old Audi A6 2.0 TDI. Over the previous two months a weird ticking appeared to come from behind the instrument cluster. After informing, Audi nothing was done. On 15-1-2012, travelling at 70mph, total electrical failure. Car turned itself off with no power assitance to the steering orsteering or brakes. Audi's technical team came out and registered quite a few faults with the car, including communication problems with the internal systems. On 20-1-2012 car still at Audi dealers, no fix found.
Problems reported of lack of smoothness and lack of control of S-tronic with 3.0 TDI, particularly when reversing.
27-10-2013:Report of 15,600 mile 2012 A6 2.0 TFSI using 1.75 litres of oil in 5,800 miles. Dealer told reader that anything down to 1250 miles per litre was deemed to be 'normal' by Audi.
14-05-2015:"Clutch judder" reported on 2013/63 Audi A6 Avant 3.0 TDI once it reaches temperature (8-10 miles from cold) and particularly after a motorway run, the clutch judders in 1st gear on take off from a standing start. More noticeable on a hill or when carrying passengers. The judder will also occur in reverse gear particularly when backing up a slope. Judder does not occur if the car is cold, in any of the other gears or on take off if the car is rolling. Problem first noticed at 10,000 miles and reported it to Audi and now at 29,000 miles it occurs all of the time. The Audi dealership doesn't seem to be able to diagnose the problem even though its technician observed the fault.
19-10-2015:Unexplained rattle from engine of 2015 Audi A6 Avant 3.0 TDI at 18,000 miles. Audi said the timing chain needed replacing. They have had the car for over 3 weeks now and have now said that the timing chain is fine and they don't know what the issues is. They have stated that the rattle wont do any damage to the engine, but they don't know what is causing the rattle.
10-12-2015:Report of armoured rubber fuel pipe of 40k mile 2012 Audi A6 3.0 TDI splitting, spraying diesel all over the engine compartment.
07-04-2016:Report of amplifier failing on Audi A6 Avant after a repair of a central locking defect. Knocked out radio and Bluetooth phone. Quoted £1,800 + VAT for replacement amp. recommended an independent car audio repair specialist.
07-04-2016:Report of driver's seat of 2015 Audi A6 Avant creaking. Admittedly tall driver who sets the seat as far back as it will go. Many attempts to fix, latest by an Audi UK technician who disassembled the seat rail and reported that the problem was worn the seat rail bearings resulting in broken seat bases.
07-07-2016:Report of problems with Multitronic in 60k mile 2011 A6. Has had transmission fluid change. But when cold parked on hill, pulling away uphill, revs rise car doesn't move, then jumps forward sometime stalling. Dealer can't find a reason. See 14-5-2016 for previous report.
20-08-2016:Report that Apple's latest upgrade to the iOS operating system of its iPhones renders them incompatible with the Audi Music Interface (AMI) system, both via Bluetooth and via a hard wire connection in Audi A6 up to 2015. Audi's 2016 cars have been updated to be compatible with Apple latest iOS.
27-01-2017:Report (in owner's words), "I have owned an Audi A6 Ultra from new (June 2014) and in that time I have had a total electrical failure and 2 steering malfunctions - the latest one just before Christmas last year when I turned the wheel and the car went straight ahead at about 15 mph. Crawley Audi acknowledged that a fault was stored with regard to communication to the steering control unit, but since the fault didn't present itself whilst in their care, they couldn't determine the fault. Their solution was to replace the steering column which - and I quote - is the best course of action at this point. They further said that it is not possible to say 100% that this fault has been rectified as it has not been possible to rectify the complaint. Crawley Audi and VW Finance are stating that I must take the car back and I am not willing to put my family at risk in the event that the steering fails again which could potentially result in serious injury or death. According to them my only other option is to pay my way out of the finance arrangement (I owe £2,500 more than the value of the car apparently) or to upgrade my car and enter another finance agreement." Advised to pay off the finance, then use Small Claims to sue the finance house for its return on the grounds that the car was dangerous.
13-03-2017:Complaint that after EA189 NOx emissions fix a 57k mile 2011 Audi A6 2.0 TDI auto is revving some 200-300rpm higher on the same journey. It seems that on all journeys the car is running faster and therefore using more fuel. Owner had timing belt changed in 2016 as well as the water pump.
22-03-2017:Report of recently bought 2011 Audi A5 2.0 TDI S line driving on motorway at 70mph, then engine gave a jerk, management light came on and engine lost power. Seemingly rectified itself, but when owner tried to pull off the engine management light stayed flashing and the engine had no power. It would not go in excess of 2,000 revs. Had to drive another 70k at 2,000 revs to get home. Engine management light and the emission control lights are on the dash and i still have no power.
03-04-2017:Report that after the NOx emissions fix on a Audi A6 2. 0TDI Utra the stop/start is affecting regenerations. Also owner finds that using Shell V-Power diesel allows engine to run at lower revs with earlier s-tronic change-ups. Owner worried that DPF not achieving sufficient temperator for active regens, but it may be that V-Power creates less soot than ordinary diesel after the fix so there is less need for regens.
24-08-2017:Report of Audi A6 TDI going in for NOx emissions fix and now engine management light is permanently lit. Probably a blocked EGR.
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.
08-05-2018:Report of 2003 Audi A6 Bi Turbo 3.0d for the past 6 weeks sporadically going into limp home mode with the engine management light flashing. Each time, re-starting the car has cleared the fault and it was been fine. Owner took it into local Audi dealership who advised the problem was the EGR valve and it would cost £1,440 to replace. Owber had taken out an Audi component level aftermarket warrantee which cost him £75 pcm. The underwriter informed him that the EGR wasn't covered because it wasn't explicitly listed under the covered items list. Owner now waiting to hear whether or not Audi UK will help with the replacement cost and labour. The car has a full Audi service history and has only done 56K miles in the 5 years it's been registered.
08-05-2018:Deliveries of Audi A6 and A7 models with V6TDI diesel engines suspended after the German KBA found they emitted excessive amounts of NOx in normal use. 60,000 more cars recalled.
02-10-2018:Report of September 2016 Audi 3 litre A6 Avant requiring new front brake pads and discs at 17,000 miles and again at 29,000 miles.
04-01-2019:Report of ACC and auto braking simultaneously failing on 2012 Audi A6 Avant. Also the satnav has started to show the car as located 50 miles from where it really is. Satnav fault might be caused by water ingress to the shark's fin GPS aerial.
09-03-2019:Intermitten judder reported from drivetrain of 2015 Audi A6 2.0 TDi 190 Ultra Start/Stop AdBlue SE Ultra 5dr Avant. Audi dealer chargesd £120 for "initial diagnosis". Wanted £480 for "further investigation", removing the transmission, after which they would quote for a fix. Seems like a dual mass flywheel problem.
04-07-2019:Report of "catastrophic manual gearbox failure, with a bill of £ 4,000" at 80,000 miles on a 2015 2.0 litre Audi A6 SE TDI Ultra bought 15 months previously.
08-01-2020:Report of warning “Gearbox overheating. Please adapt driving style” in 2012 Audi A6 3.0 TFSI 7-speed S tronic. Briefly refused to change up from 1st or 2nd gear. This occurred twice in quick succession while in slow-moving traffic after a 10-mile motorway run, then cleared with no further problem for the remaining 5 miles of urban traffic conditions. Owner's driving style is already smooth rather than fast, with no aggressive acceleration. Transmission oil changed every 2 years/20,000 miles. Owner suspects 'PCB'.
