2015 Citroen Relay MOT pass rate: 73.6% (4,069 tests)
Is the 2015 Relay getting worse?
Pass rate of 2015-registered cars across recent test years:
| Test year | Pass rate | |
|---|---|---|
| 2023 | 74.9% -5.6 vs same-age |
|
| 2024 | 74.1% -4.5 vs same-age |
|
| 2025 | 71.8% -5.2 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 Relay?
