2017 BMW 435 MOT pass rate: 86.6% (6,079 tests)
Is the 2017 435 getting worse?
Pass rate of 2017-registered cars across recent test years:
| Test year | Pass rate | |
|---|---|---|
| 2023 | 89.3% +3.5 vs same-age |
|
| 2024 | 85.3% +1.4 vs same-age |
|
| 2025 | 85.0% +2.6 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.

What mileage is too high for a 2017 435?
