2017 DS DS4 MOT pass rate: 75.9% (2,911 tests)
Is the 2017 DS4 getting worse?
Pass rate of 2017-registered cars across recent test years:
| Test year | Pass rate | |
|---|---|---|
| 2023 | 78.8% -7.0 vs same-age |
|
| 2024 | 74.9% -8.9 vs same-age |
|
| 2025 | 73.9% -8.5 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 2017 DS4?
The median tested example shows 51,226 miles. Anything far beyond that isn't automatically bad — a motorway-mile car with consistent service records often beats a low-mileage school-run car — but price accordingly and scrutinise the mileage trail for gaps or drops.
