2015 BMW 430 MOT pass rate: 84.4% (7,646 tests)
Is the 2015 430 getting worse?
Pass rate of 2015-registered cars across recent test years:
| Test year | Pass rate | |
|---|---|---|
| 2023 | 86.4% +5.8 vs same-age |
|
| 2024 | 83.9% +5.4 vs same-age |
|
| 2025 | 82.9% +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.
