330e Sport Pro Auto: above-average pass rates, with caveats
Across 1,041 MOT tests, the 330e Sport Pro Auto returns 84.8% first-time pass — above 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 40,895, 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.
