2018 Audi Q8 MOT pass rate: 92.6% (1,807 tests)
Is the 2018 Q8 getting worse?
Pass rate of 2018-registered cars across recent test years:
| Test year | Pass rate | |
|---|---|---|
| 2023 | 92.1% +4.0 vs same-age |
|
| 2024 | 94.1% +7.9 vs same-age |
|
| 2025 | 91.8% +7.0 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 2018 Audi Q8 reliable?
2018-registered examples passed 92.6% of their MOT tests (1,807 tests, 2023–2025), +6.3 points versus all UK cars registered in the same year. At roughly 8 years old with a median 51,490 miles, condition now varies car by car — always check the individual MOT history.
What mileage is too high for a 2018 Q8?
The median tested example shows 51,490 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.
