This 2016 Audi A6 TDI is a serious reliability concern: only 47.4% pass their MOT first time, nearly 33 percentage points below the UK average of 80%. With a median CarHunch score of 50 and zero dangerous defects recorded across 518 vehicles, the failures aren't safety-critical, but they're frequent and costly enough to deter most buyers.
At 77,646 miles median for an eight-year-old car, these A6s are running fairly high mileage, which partly explains the failure rate—but the 0.14 average failures per vehicle suggests systemic weak points rather than just age-related wear. If you're seriously considering one, budget for a pre-purchase inspection targeting the diesel engine, transmission, and emissions kit, and factor in regular specialist servicing costs.
The 2016 Audi A6 Sline Black Ed TDI Ultra SA passes its MOT first time more often than most UK vehicles (92.7% vs ~80% average) — and when it does fail, it's usually something minor and cheap to fix.
These stats describe 518 vehicles as a group. The specific vehicle you're looking at could be the one good example or the one outlier. Run its registration to find out.
