The picture
Across 549 MOT tests, the Nv400 Tekna Dci returns 77.6% first-time pass — roughly in line with the UK fleet average. The single most-logged Major fail is windscreen damage. A cosmetically defective lens and a number-plate lamp out round out the top three. Average tested mileage sits at 64,425, 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.
