Nv250 Acenta Dci: middle-of-the-pack on first-time pass
Across 612 MOT tests, the Nv250 Acenta Dci returns 73.9% first-time pass — below the UK fleet average. The single most-logged Major fail is brake pads worn below 1.5 mm. Windscreen damage and a number-plate lamp out round out the top three. Average tested mileage sits at 42,100, 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.
