Is the 2017 A8 getting worse?
Pass rate of 2017-registered cars across recent test years:
| Test year | Pass rate | |

|
| 2024 | 93.6% +9.7 vs same-age |
|
| 2025 | 93.8% +11.4 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.
