2018 Renault Master MOT pass rate: 85.5% (2,205 tests)
Is the 2018 Master getting worse?
Pass rate of 2018-registered cars across recent test years:
| Test year | Pass rate | |
|---|---|---|
| 2023 | 87.0% -1.1 vs same-age |
|
| 2024 | 85.6% -0.6 vs same-age |
|
| 2025 | 83.9% -0.8 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 Master?
