Daily 35c12 Mwb: a below-average pass rate worth digging into
Across 985 MOT tests, the Daily 35c12 Mwb returns 59.4% first-time pass — near the bottom of the UK fleet average. The single most-logged Major fail is windscreen damage. A weak handbrake and a number-plate lamp out round out the top three. Average tested mileage sits at 144,397, 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.
