2015 Mercedes-Benz E MOT pass rate: 81.5% (63,547 tests)
Is the 2015 E getting worse?
Pass rate of 2015-registered cars across recent test years:
| Test year | Pass rate | |
|---|---|---|
| 2023 | 82.6% +2.1 vs same-age |
|
| 2024 | 81.1% +2.6 vs same-age |
|
| 2025 | 80.7% +3.7 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 2015 E?
