FAQs

Is a 2015 Audi A5 reliable?

2015-registered examples passed 82.1% of their MOT tests (30,666 tests, 2023–2025), +3.3 points versus all UK cars registered in the same year. At roughly 11 years old with a median 78,499 miles, condition now varies car by car — always check the individual MOT history.

What mileage is too high for a 2015 A5?

The median tested example shows 78,499 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 2015 A5?

In this cohort petrols pass 85.4% of tests against 80.8% 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.
