Boxer 440 L4 Bluehdi: a strong MOT record by UK norms
Across 712 MOT tests, the Boxer 440 L4 Bluehdi returns 88.3% first-time pass — comfortably ahead of the UK fleet average. The single most-logged Major fail is a weak handbrake. A cosmetically defective lens and missing break glass hammer (where required) round out the top three. Average tested mileage sits at 10,299, 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.
