A3 Technik 35 Tfsi: a strong MOT record by UK norms
Across 747 MOT tests, the A3 Technik 35 Tfsi returns 90.2% first-time pass — comfortably ahead of the UK fleet average. The single most-logged Major fail is a seriously damaged tyre. Windscreen damage and a tyre with the cords showing round out the top three. Average tested mileage sits at 24,325, which is the lens to read those failure rankings through.
