Is the 2017 A1 getting worse?

Pass rate of 2017-registered cars across recent test years:

Test year	Pass rate
2023	84.1% -1.7 vs same-age
2024	81.2% -2.7 vs same-age
2025	79.9% -2.5 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 2017 Audi A1 reliable?

2017-registered examples passed 81.7% of their MOT tests (67,899 tests, 2023–2025), -2.3 points versus all UK cars registered in the same year. At roughly 9 years old with a median 45,844 miles, condition now varies car by car — always check the individual MOT history.

What mileage is too high for a 2017 A1?

The median tested example shows 45,844 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 2017 A1?

In this cohort petrols pass 82.3% of tests against 77.6% 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.
