Is the 2014 Viano getting worse?
Pass rate of 2014-registered cars across recent test years:
| Test year | Pass rate | |
|---|---|---|
| 2023 | 77.1% -0.3 vs same-age |
|
| 2024 | 76.3% +0.7 vs same-age |
|
| 2025 | 72.0% -2.4 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 2014 Viano?
