2017 DS DS3 MOT pass rate: 77.2% (21,340 tests)
Is the 2017 DS3 getting worse?
Pass rate of 2017-registered cars across recent test years:
| Test year | Pass rate | |
|---|---|---|
| 2023 | 80.6% -5.2 vs same-age |
|
| 2024 | 77.4% -6.5 vs same-age |
|
| 2025 | 73.7% -8.7 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.

FAQs
Is a 2017 DS DS3 reliable?
2017-registered examples passed 77.2% of their MOT tests (21,340 tests, 2023–2025), -6.8 points versus all UK cars registered in the same year. At roughly 9 years old with a median 43,695 miles, condition now varies car by car — always check the individual MOT history.
What mileage is too high for a 2017 DS3?
The median tested example shows 43,695 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.
Should I buy the petrol or diesel 2017 DS3?
In this cohort petrols pass 78.1% of tests against 73.6% for diesels. Mileage and use can explain part of that gap, so treat it as a reason to inspect DPF and emissions history, not a fuel-type verdict.
