2018 Dacia Logan MOT pass rate: 81.1% (5,294 tests)
Is the 2018 Logan getting worse?
Pass rate of 2018-registered cars across recent test years:
| Test year | Pass rate | |
|---|---|---|
| 2023 | 83.6% -4.5 vs same-age |
|
| 2024 | 81.0% -5.2 vs same-age |
|
| 2025 | 78.7% -6.0 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 2018 Logan?
