2015 Audi Q3 MOT pass rate: 81.0% (41,907 tests)
Is the 2015 Q3 getting worse?
Pass rate of 2015-registered cars across recent test years:
| Test year | Pass rate | |
|---|---|---|
| 2023 | 83.8% +3.2 vs same-age |
|
| 2024 | 81.3% +2.8 vs same-age |
|
| 2025 | 77.9% +0.9 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 2015 Audi Q3 reliable?
2015-registered examples passed 81.0% of their MOT tests (41,907 tests, 2023–2025), +2.3 points versus all UK cars registered in the same year. At roughly 11 years old with a median 70,209 miles, condition now varies car by car — always check the individual MOT history.
What mileage is too high for a 2015 Q3?
The median tested example shows 70,209 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 Q3?
In this cohort petrols pass 84.5% of tests against 79.5% 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.
