Summary


The Audi A6 is a large executive vehicle available in saloon and estate (called Avant) body styles. This is the fourth-generation model, which first arrived in 2011. After a mid-life facelift in 2015, this A6 iteration was replaced by the current model in 2018.

In usual Audi fashion, top-spec performance versions of the A6 saloon and estate were called the S6. There was also the A6 allroad quattro model, which had a beefed-up estate body and improved ground clearance for off-road driving. Finally, the performance-focused RS 6 Avant completed the range, but that’s not covered on this page.

Available with a choice of several petrol and diesel engines, the fourth-generation A6 consistently received good to very good scores from the UK media during its time on sale – praised by Top Gear for its “unarguably lovely” interior which was both practical and sophisticated, and commended by Auto Trader for its “refined and really economical engines”.

While Audi S6 models also garnered praise for their straight-line speed and driving dynamics, the performance of the standard A6 models did not excite reviewers to the same extent, as a few motoring outlets suggested that the A6 wasn’t as engaging as some of its upmarket saloon rivals.

“If you’re in the market for an economical, spacious and quietly gratifying car then the Audi A6 is highly recommended”, concluded Autocar‘s Matt Saunders. “Those seeking a more engaging and rewarding drive should perhaps opt for the equivalent BMW 5 Series.”

As of March 2024, the fourth-generation Audi A6 holds a Used Car Expert Rating of E, with a score of just 50%.

Notes on safety rating

The fourth-generation Audi A6 was originally tested by Euro NCAP back in 2011 and awarded a five-star safety rating. However, this rating expired in January 2018 and is no longer valid as the car no longer meets the standards required for this rating. This is normal practice, as Euro NCAP reviews its ratings on most cars annually with most ratings expiring after about six or seven years.

However, if you are comparing a used Audi A6 to vehicles of similar age, whose ratings will have probably also expired, its safety rating score is still useful.

Eco rating


No eco rating

The fourth-generation Audi A6 was not tested by Green NCAP during its production life as it pre-dated the organisation.

Reliability data provided exclusively for The Car Expert by MotorEasy

All data based on MotorEasy average workshop costs for extended car warranty claims

As of March 2024, the Audi A6 has a poor reliability score of just 40%, according to exclusive warranty data provided by our partners at MotorEasy. This score covers this fourth-generation model as well as both newer (2018 onwards) and previous (pre-2011) versions.

The most common problems with the A6 to date relate to its electrical system, with an average repair bill of more than £400. Engine problems are very expensive, with an average repair bill of about £1,700, and are worryingly common. Gearbox repair bills are also hugely expensive at about £2,700, while other repair bills are all on the expensive side as well.

If you’re looking at a used Audi A6, make sure any extended warranty cover you purchase covers all of these potential problem areas.
