Xj 6 S Diversion: a strong MOT record by UK norms
Across 627 MOT tests, the Xj 6 S Diversion returns 88.0% first-time pass — comfortably ahead of the UK fleet average. The single most-logged Major fail is a non-functioning shock absorber. Tyre tread under the limit and brake pads worn below 1.0 mm round out the top three. Average tested mileage sits at 24,103, 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.
