Q3 S Line Black Ed 35 Tfsi: a strong MOT record by UK norms

Across 1,449 MOT tests, the Q3 S Line Black Ed 35 Tfsi returns 91.7% first-time pass — comfortably ahead of the UK fleet average. The single most-logged Major fail is a seriously damaged tyre. Tyre tread under the limit and brake pads worn below 1.5 mm round out the top three. Average tested mileage sits at 26,317, 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.

Buying or keeping a Q3 S Line Black ED 35 Tfsi?

Use the failure ranking as a pre-test checklist or a haggling lever. Treat the headline pass rate as a fleet-wide trend, not a guarantee on any individual car.

If you own a Q3 S Line Black ED 35 Tfsi and your last MOT looked nothing like the ranked failures above, that's normal — individual cars vary widely. The ranking shows the patterns testers flag most often across the country.
