The picture
Quattro: above-average pass rates, with caveats
Across 625 MOT tests, the Quattro returns 83.4% first-time pass — above the UK fleet average. The single most-logged Major fail is a lamp out. A number-plate lamp out and worn suspension bushes round out the top three. Average tested mileage sits at 111,534, 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.

Counts cover Major and Dangerous defects logged at test. Advisory items excluded so this shows why a car was rejected, not just what the tester flagged in passing.

Buying or keeping a Quattro?
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 Quattro 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.
