Expert S L2 Bluehdi: a strong MOT record by UK norms
Across 507 MOT tests, the Expert S L2 Bluehdi returns 92.7% first-time pass — comfortably ahead of the UK fleet average. The single most-logged Major fail is a number-plate lamp out. A defective wiper blade and brake pads worn below 1.5 mm round out the top three. Average tested mileage sits at 26,948, 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.
