Sprinter 314 Progressive Cdi: middle-of-the-pack on first-time pass
Across 2,167 MOT tests, the Sprinter 314 Progressive Cdi returns 77.7% first-time pass — roughly in line with the UK fleet average. The single most-logged Major fail is a missing CV-joint boot. A weak handbrake and windscreen damage round out the top three. Average tested mileage sits at 78,035, 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.
