Ds3: middle-of-the-pack on first-time pass
Across 40,211 MOT tests, the Ds3 returns 74.9% first-time pass — below the UK fleet average. The single most-logged Major fail is a missing CV-joint boot. A broken or weak spring and tyre tread under the limit round out the top three. Average tested mileage sits at 45,810, which is the lens to read those failure rankings through. If you own one and the next test is close, the ranked list below is a sensible pre-test checklist.

Buying or keeping a Ds3?
Use the failure ranking as a pre-test checklist or a haggling lever. Treat the headline pass rate as a fleet-wide trend, not a guarantee on any individual car.
If you own a Ds3 and your last MOT looked nothing like the ranked failures above, that's normal — individual cars vary widely. The ranking shows the patterns testers flag most often across the country.
