Master Lm35 Business + Dci: middle-of-the-pack on first-time pass
Across 464 MOT tests, the Master Lm35 Business + Dci returns 75.9% first-time pass — roughly in line with the UK fleet average. The single most-logged Major fail is windscreen damage. A number-plate lamp out and wipers that don't clear the screen round out the top three. Average tested mileage sits at 62,300, 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.
