2015 Citroen C4 MOT pass rate: 70.4% (81,735 tests)
Is the 2015 C4 getting worse?
Pass rate of 2015-registered cars across recent test years:
| Test year | Pass rate | |
|---|---|---|
| 2023 | 73.2% -7.4 vs same-age |
|
| 2024 | 69.6% -8.9 vs same-age |
|
| 2025 | 68.1% -8.9 vs same-age |

What mileage is too high for a 2015 C4?
