Id4 Life: a strong MOT record by UK norms

Across 1,567 MOT tests, the Id4 Life returns 95.0% first-time pass — comfortably ahead of the UK fleet average. The single most-logged Major fail is tyre tread under the limit. A defective wiper blade and a seriously damaged tyre round out the top three. Average tested mileage sits at 31,075, 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 an Id4 Life?

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 an Id4 Life 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.
