The picture
Id3 Business: a strong MOT record by UK norms
Across 483 MOT tests, the Id3 Business returns 92.5% first-time pass — comfortably ahead of the UK fleet average. The single most-logged Major fail is a seriously damaged tyre. Tyre tread under the limit and a tyre with the cords showing round out the top three. Average tested mileage sits at 24,202, 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 Business?
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 Business 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.
