Audi A6 Avant (2011 – 2018) At A Glance
Good-looking and exceedingly well-built premium big estate, roomy interior and practical boot, diesels offer fuel economy and performance.
Solid and assured to drive but not very exciting, shape of boot limits load-carrying capacity, sporty-looking S line versions have inferior ride quality.
The Audi A6 Avant is an upmarket car that continues the German brand’s long-running line of Avant estates. Always one of the more svelte-looking wagons, this generation of A6 Avant boasts a rakish rear window line, plus a typically Audi high-quality interior and vast array of engines, gearboxes, trim levels and driven wheel configurations. If you need a spacious, classy holdall, forget the omnipresent SUV and try one of these instead.
Audi has been committed to the idea of large estate cars since the 1970s. It took rival BMW more than a decade to roll out an alternative. However, unlike boxy alternatives from Mercedes-Benz and Volvo, Audi has always infused Avants with a bit more style. It’s the aesthete’s load-lugger, if you like.
This 2011 version was, true to form, an extremely sophisticated proposition at launch. Vorsprung durch Technik was evident from the inch-perfect, sharply-cut design and impeccable interior – and Audi built upon the car’s impressive haul of onboard tech throughout its life.
It feels good to sit inside, thanks to the beautiful finish of the dashboard and controls. Build quality is exemplary, with Audi having an edge here over its premium German rivals.
Even the entry-level SE grade has leather seats, for a luxury feel, plus all the features you’d expect to find on an executive car. Later SE Executive versions are even better in this regard. More desirable is S line grade, though – it offers large alloy wheels, bolder styling and superb sports seats.
The Audi is a very roomy car. It feels big sitting behind the wheel, while those in the rear have an abundance of headroom and legroom. The boot is commodious and easy to use: overall capacity is bettered only by the Mercedes-Benz E-Class estate. Look out for models with the optional load-lashing kit, using the standard rails built into the side of the boot.
In terms of engines, the Audi’s popularity with company car drivers means most are powered by the 2.0-litre TDI diesel engine. That may sound small for a car this size, but with up to 190PS it delivers ample bang for your buck.
It’s also very fuel efficient, officially averaging more than 60mpg (look for models wearing the ‘Ultra’ badge, as these are the most economical of all). You can choose an automatic gearbox as well as a manual.
Comfort levels are high, and it feels made for sitting on the motorway and eating up miles without fuss. Models with the Quattro all-wheel-drive system give extra confidence in winter weather, too.
We also need to mention the range-topping Audi A6 Avant: the monstrous RS6. With a colossal 560PS from its 4.0-litre twin-turbo V8 engine, this is an estate car that can take on Porsche – and one that’s become a cult car in its own right.
Despite being a model that still looks fresh and sophisticated, A6 Avant prices are becoming surprisingly accessible. Early models can now be found from around £10,000, and there’s an abundance of choice if you spend a few thousand more. Built for the long run, it’s easy to see why the Audi A6 Avant is a tempting used car.

Audi A6 Avant (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 22–58 mpg
Audi A6 Avant (2011 – 2018): Handling and ride quality
Enthusiastic drivers should gravitate towards the BMW 5 Series Touring or Jaguar XF Sportbrake if they want a more engaging experience.
What the Audi does brilliantly is feel robust, confident and very assured. It is safe and stable, with good traction and effortless, relaxing confidence on the motorway. It devours high miles and should leave you feeling fresh at the end of a journey. That’s particularly true if you go for a Quattro all-wheel drive version, which remains unruffled in even the grottiest winter conditions.
Ride quality is decent, and at its best on either SE models with smaller wheels, or cars with optional air suspension. S line versions are notably a little firmer, though, due to their bigger wheels and 20mm lower suspension – although even they are still compliant on the motorway.
Audi A6 Avant (2011 – 2018): Engines
A 2.0-litre four-cylinder engine doesn’t sound like it will live up to the A6 Avant’s ‘executive’ billing, but we think you’ll be surprised. It generally fades nicely into the background and is almost inaudible when cruising. It’s only when you rev it through that it sounds a bit rattly – but as it has a decent amount of pulling power, you shouldn’t have to do this often.
For most, the 2.0-litre TDI will be perfectly fine – although the even smoother nature and genuinely strong surge from the V6 motors will appeal to some. The most striking is the twin-turbo 3.0-litre V6, called BiTDI, which serves up 320PS and a brilliantly muscular feel.
The twin-turbo V8 in the RS6 is an absolute rocketship, with staggering acceleration, particularly away from the line. It turns the A6 Avant into a roomy five-seater that can square up to a Porsche sports car
Audi A6 Avant (2011 – 2018): Safety
Euro NCAP awarded the Audi A6 Avant a full five-star safety score when it tested the model in 2011. Driver protection was rated an excellent 91 percent, while safety assist features scored 86 percent. The availability of optional gadgets such as a blind-spot warning system and lane-keep assist helped here, and you can even get a head-up display.
A really intriguing feature is optional night vision. This uses a thermal imaging camera that displays what’s up ahead on the screen between the instruments. You’ll be amazed at what it can pick out. Sadly, as it was a very expensive option when new, it’s rare on the second-hand market.
Audi A6 Avant (2011 – 2018): Towing
The Audi A6 Avant makes a fine tow car, with even the entry-level 2.0-litre TDI offering a 1,800kg maximum towing capacity. The 3.0-litre V6 takes this up further, to two tonnes.
Audi offered a factory-fit towbar as an option, and caravan or boat owners might like to seek out a car fitted with air suspension. This ensures the ride height remains level, no matter how heavy-duty the load being towed is.

Audi A6 Avant (2011 – 2018): Practicality
It’s hard to find fault here – the Audi A6 Avant is very commodious and practical. The driver’s seat has a tremendous amount of adjustability, so will prove accommodating for all shapes and sizes. This doesn’t come at the expense of rear-seat space either. The A6 actually vies with the larger Audi A8 luxury car for passenger room.
With the seats up, it offers 565 litres of space, and folding them down extends this to 1,680 litres. It’s actually larger than a Volvo V70 estate, and it’s only the sporty rake of the rear window that ultimately caps overall capacity – the boxier-looking Mercedes-Benz E-Class estate is larger overall.
The optional load-fixing kit is a neat extra. It comprises inertia-reel straps that fit into the chrome rails at the sides of the boot floor. These stop objects rolling around in the enormous load bay.
Audi A6 Avant (2011 – 2018): Quality and finish
Audi is famous for its high standards of quality and finish. This generation of A6 Avant is an exemplar in this regard, with beautifully rich and deep paintwork, precise panel fit and, inside, almost luxury-level surfaces and plastics. Everything looks and feels superb, even the parts you don’t normally see.
We like the large, attractive instruments and love some of the alternative trim inlays. Audi offered a large degree of customisation when new, and you’ll find some very smartly-finished models on the second-hand market.
Audi A6 Avant (2011 – 2018): Infotainment
As standard, this generation of Audi A6 Avant came with a 6.5-inch colour screen in the centre of the dashboard. It’s not a touchscreen, being controlled instead by the Audi MMI dial in the centre console. Some models have MMI Touch, which includes a touchpad so drivers can ‘write’ navigation inputs with their finger.
It’s a good-looking system and fairly straightforward to use. Sat nav is fitted to all, via an SD card (there are two SD card slots). The optional upgrade was called MMI Navigation Plus, which saw the screen grow to an 8.0-inch display. Apple CarPlay and Android Auto are absent, however, as such connectivity wasn’t around for this era of car.
Audi A6 Avant (2011 – 2018) value for money
Audi A6 Avant (2011 – 2018): Prices
The Audi A6 Avant is an executive car, with the estate costing around £1500 more than the saloon to buy when new. The premium is narrower on second-hand models, but you’ll still pay a little more for an Avant over a comparable four-door.
We’re seeing early 2011 models now down to around £10,000. Cars at this level have usually covered above-average mileage, but the A6 Avant is built to take it. Such bargains may look and feel anything but tired.
There’s more choice if you can spend a few thousand more – and while the cheapest cars will generally all be SE grade, upping your budget will open up the chance to pick up the appealing S line variant, with its sportier extras and supportive sports seats.
The vast majority of second-hand A6 Avant models will, reflecting sales when new, be fitted with the 2.0-litre TDI diesel engine. Those who want something extra will have to search a little harder – and up their budget. The 3.0-litre TDI V6 costs from around £16,000, while the powerful BiTDI version is starting to drop below the £20,000 mark.
The used car market seems less fussy about the difference between front-wheel-drive and Quattro all-wheel-drive models, though. You shouldn’t have to pay a premium to get all-wheel, all-weather grip, although there will be a small penalty in terms of overall fuel consumption
Audi A6 Avant (2011 – 2018): Running Costs
The very best 2.0 TDI models – they’re badged ‘Ultra’ – average more than 60mpg in the official fuel economy test. You won’t quite see that in everyday driving, but you’ll still get great figures, and the resultant low CO2 emissions mean VED (road tax) is extremely affordable.
Audi facelifted the A6 Avant in 2014. Frankly, it’s hard to tell the difference, as the changes were minimal – but all engines did become compliant with Euro 6 emissions rules, meaning even diesels will escape Ultra Low Emissions Zone-style charges for many years to come.
There are several different types of automatic gearbox. Look out for the one called S Tronic, which is the most efficient of all, delivering fuel economy figures hardly any worse than a comparable manual.
Insurance groups are reasonable, starting from group 27 for the most basic 2.0-litre TDI SE variants. S line alternatives are generally a grade or two higher, and both petrol engines and the V6 diesels are a bit steeper still.

New A6 Avant revealed
Even more accommodating Audi Avant trims away up to 70kg in the interest of efficiency and agility Priced from £32,100 OTR, the new A6 Avant offers major efficiency improvements helped by state-of-the art construction processes which reduce weight by up to 70kg, and offers an impressive and increased carrying capacity of up to 1,680 litres. Another highlight, due later in 2011, will be a potent new 313PS twin-turbo V6 TDI engine which will be shared with the A6 Saloon.
Thanks to the use of aluminium components, which make up roughly 20 per cent of the body, gross weight of ther newe Audi A6 Avant has been reduced by as much as 70 kilograms, depending on engine, compared with the previous model. The A6 Avant 2.0 TDI, for example, has a kerb weight of just 1,640 kilograms.
The luggage compartment in this new A6 Avant can be opened automatically simply by ‘gesturing’ with a foot to two sensors beneath the rear bumper if the optional advanced key feature is added. The A6 Avant has a capacity of 565 litres, which can be increased to 1,680 litres by folding down the rear seat backs. The load bay has luggage lashing eyes, side restraining straps, bag hooks, a double cargo floor, a rail luggage fixing system, a dirt-resistant tray and roof rails as standard. A through-load facility and a fixing set that uses the two standard rails in the cargo floor are optional.
A choice of four engines featuring direct fuel injection will be available for the new A6 Avant in the UK: one petrol engine and three TDI units. They develop between 177PS and 300PS, the top figure belonging to the supercharged 3.0 TFSI petrol model. The line-up also includes the 3.0-litre V6 TDI in 204PS and 245PS forms and the even more efficient 177PS 2.0-litre TDI, which with its 56.5mpg potential and low 132g/km CO2 output offers an outstanding combination of strong performance and comparatively low running costs.
Later in 2011 an all-new 3.0-litre twin-turbo TDI will be the most potent V6 and the fourth diesel-powered option in the range. Thanks to a two-stage turbocharger that delivers a maximum boost pressure of up to 3.2 bar, the TDI flagship will take just 5.4 seconds to reach 62mph from rest, and will be electronically limited to a 155mph top speed.
Transmission options, based on the engine choice, will include a manual six-speed transmission or multitronic CVT for front-wheel-drive models, and the new seven-speed S tronic twin-clutch transmission for quattros. Each unit features a wide gear-ratio spread which gives a further boost to overall efficiency.
The latest generation quattro all-wheel-drive with a crown gear centre differential and a torque-vectoring function for optimum traction, stability and response will be standard for the 3.0 TDI 245PS and 3.0-litre TFSI petrol models. For the top-of-the-line engines, the quattro sport differential – which is capable of apportioning torque between the rear wheels – will also be offered as an option.
New energy-efficient electromechanical power steering, in conjunction with the lightweight suspension set-up with its considerable aluminium content, will further refine handling. The reduced unsprung mass will also favour ride comfort – which has already been highly praised in the A6 Saloon – and which can be enhanced even further if the optional adaptive air suspension is chosen.
The Audi drive select adaptive dynamics system will also be standard in the new A6 Avant, allowing drivers to fine-tune the car’s responses as desired via the Multi Media Interface (MMI) screen. In front-wheel-drive models the latest Electronic Stability Programme (ESP) with electronic limited slip differential will help to maintain optimum control without impairing responsiveness during enthusiastic driving.
As Audi customers have come to expect, the spacious interior combines the latest Audi design language with the finest materials constructed to the very highest of standards, and embellishes this with exceptional technological input. The cabin’s focal point is the MMI 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 which, uniquely in the premium sector at this level, is standard.
An eight-inch monitor and fingertip-sensitive touch pad are available as an upgrade from MMI to MMI Navigation Plus with 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 ultra-intelligent 3D navigation mapping, the upgraded MMI system can store audio tracks and telephone data on its sizeable hard disk.
Online services including news and weather information supplied by Google will be accessible if the Mobile Telephone Preparation High and MMI Navigation Plus options are 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 universal mobile telecommunications system (UMTS) module to the MMI monitor for navigation purposes. Through its wireless local area network (WLAN) link, passengers will also be able to connect to the internet with up to eight devices at once.
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, helping the car to match its system functions to its surroundings.
Also on the options list is a night vision assistant that uses a thermal-imaging camera to highlight ‘warm-blooded’ road users in front of the car, a head-up display and a park assist system which automatically takes care of steering to manoeuvre into parallel or perpendicular parking spaces. More familiar options such as the Audi side assist blind spot warning system, the Audi lane assist lane departure detection system and the Bang & Olufsen Advanced Sound System are also available.
Two specification levels - SE and S line – will be offered in the UK, each including alloy wheels, leather upholstery, cruise and front and rear parking controls, SD-based satellite navigation, Bluetooth phone preparation, split/folding rear seats and light and rain sensors. S line models will add larger 18-inch alloy wheels, Xenon headlamps with LED daytime running lamps, sports suspension, upgraded Valcona leather upholstery and an exclusive S line exterior and interior styling treatment.

New 313PS Biturbo TDI engine now available
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.

Black Edition versions of the A6 launched
Priced from £36,970 OTR to £51,025 OTR, Black Edition distinguishing features start from the ground up with 20-inch rotor-design alloy wheels with a dark titanium finish. On the outside they get 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. Fittingly, the A6 Avant Black Edition is also equipped with black roof rails.
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 already comprehensive 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 is also available in conjunction with all engines from the 177PS 2.0-litre TDI upwards, excluding S6 models, and with either front-wheel-drive or quattro all-wheel-drive.
October 2013
A6 3.0 TDI quattro 204PS announced
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 - Avant models offer up to 61.4mpg with 119g/km (outgoing equivalent 55.4mpg, 135g/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
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
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.
14-11-2016:Report of 2013 A6 Avant 2.0TDI, driving to work at 40-45mph for approx 10 miles the computer was reading between 52-60 MPG every day. After the NOx defeat software upgrade the car is only doing 38-43 MPG.
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. This was resolved by Complete Car Care in Theddingworth Leics bringing in a locksmith with VAG.com. The only errors showing were the left wing mirror indicator bulb which they replaced and the Sat Nav which they found tobe due to water ingress tp the aerial. A new aerial which he colour coded and fitted using extra sealant a clear out on the codes and the sat Nav and ACC are all working perfectly. Price including the aerial, colour coding, diagnosis and fitting £350 inc VAT.
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.
