Transit Custom 340leader Eblue: middle-of-the-pack on first-time pass
Across 2,443 MOT tests, the Transit Custom 340leader Eblue returns 79.3% first-time pass — roughly in line with the UK fleet average. The single most-logged Major fail is windscreen damage. Brake pads worn below 1.5 mm and wipers that don't clear the screen round out the top three. Average tested mileage sits at 55,408, 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.
