The picture
Across 496 MOT tests, the E-Tron S Line 55 Quattro returns 87.9% first-time pass — comfortably ahead of the UK fleet average. The single most-logged Major fail is a tyre with the cords showing. A seriously damaged tyre and tyre tread under the limit round out the top three. Average tested mileage sits at 28,470, 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.
