L200 Challenger Di-D Auto: a strong MOT record by UK norms
Across 956 MOT tests, the L200 Challenger Di-D Auto returns 86.2% first-time pass — comfortably ahead of the UK fleet average. The single most-logged Major fail is brake pads worn below 1.5 mm. Windscreen damage and wipers that don't clear the screen round out the top three. Average tested mileage sits at 47,893, 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.
