Is the 2011 A4 getting worse?

Pass rate of 2011-registered cars across recent test years:

Test year	Pass rate
2023	76.3% +6.2 vs same-age
2024	74.7% +5.8 vs same-age
2025	74.3% +5.9 vs same-age

The raw rate normally falls as cars age. The “vs same-age” figure compares this cohort with all UK cars registered in the same year, so normal ageing is not mistaken for a bad model year.

FAQs

Is a 2011 Audi A4 reliable?

2011-registered examples passed 75.1% of their MOT tests (40,807 tests, 2023–2025), +6.0 points versus all UK cars registered in the same year. At roughly 15 years old with a median 126,868 miles, condition now varies car by car — always check the individual MOT history.

What mileage is too high for a 2011 A4?

The median tested example shows 126,868 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 2011 A4?

In this cohort petrols pass 79.1% of tests against 74.5% 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.
