FAQs
Is a 2016 Audi A6 reliable?
2016-registered examples passed 86.7% of their MOT tests (39,274 tests, 2023–2025), +5.4 points versus all UK cars registered in the same year. At roughly 10 years old with a median 81,324 miles, condition now varies car by car — always check the individual MOT history.
What mileage is too high for a 2016 A6?
The median tested example shows 81,324 miles. Anything far beyond that isn't automatically bad — a motorway-mile car with consistent service records often beats a low-mileage school-run car — but price accordingly and scrutinise the mileage trail for gaps or drops.
Should I buy the petrol or diesel 2016 A6?
In this cohort petrols pass 89.7% of tests against 86.6% for diesels. Mileage and use can explain part of that gap, so treat it as a reason to inspect DPF and emissions history, not a fuel-type verdict.
