The picture
Id3 Family: a strong MOT record by UK norms
Across 609 MOT tests, the Id3 Family returns 93.3% first-time pass — comfortably ahead of the UK fleet average. The single most-logged Major fail is a tyre with the cords showing. A seriously damaged tyre and a defective wiper blade round out the top three. Average tested mileage sits at 21,843, 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 Id3 Family?
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 Id3 Family 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.
