M340i Xdrive Auto: a strong MOT record by UK norms
Across 2,102 MOT tests, the M340i Xdrive Auto returns 87.8% first-time pass — comfortably ahead of the UK fleet average. The single most-logged Major fail is a seriously damaged tyre. A seriously damaged tyre and tyre tread under the limit round out the top three. Average tested mileage sits at 25,813, 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.
