The picture
Across 2,127 MOT tests, the 330e M Sport Auto returns 85.9% first-time pass — comfortably ahead of the UK fleet average. The single most-logged Major fail is tyre tread under the limit. A seriously damaged tyre and a tyre with the cords showing round out the top three. Average tested mileage sits at 39,631, 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.
