A1 Technik 25 Tfsi: a strong MOT record by UK norms
Across 1,529 MOT tests, the A1 Technik 25 Tfsi returns 89.8% first-time pass — comfortably ahead of the UK fleet average. The single most-logged Major fail is tyre tread under the limit. A seriously damaged tyre and windscreen damage round out the top three. Average tested mileage sits at 23,257, which is the lens to read those failure rankings through.
