2017 BMW 330 MOT pass rate: 87.9% (18,677 tests)
Is the 2017 330 getting worse?
Pass rate of 2017-registered cars across recent test years:
| Test year | Pass rate | |
|---|---|---|
| 2023 | 89.0% +3.3 vs same-age |
|
| 2024 | 87.9% +4.0 vs same-age |
|
| 2025 | 86.9% +4.5 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.
