Boxer 435 Pro L4h2 Bluehdi: middle-of-the-pack on first-time pass
Across 1,312 MOT tests, the Boxer 435 Pro L4h2 Bluehdi returns 72.4% first-time pass — below the UK fleet average. The single most-logged Major fail is windscreen damage. A weak handbrake and a lamp out round out the top three. Average tested mileage sits at 63,773, 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.
