Q3 Sport 35 Tdi S-A: a strong MOT record by UK norms
Across 559 MOT tests, the Q3 Sport 35 Tdi S-A returns 91.8% first-time pass — comfortably ahead of the UK fleet average. The single most-logged Major fail is windscreen damage. Tyre tread under the limit and a seriously damaged tyre round out the top three. Average tested mileage sits at 31,115, 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.
