The list shows what a Audi is more likely than other cars to fail on, which is where to look on a pre-MOT check or a used-car inspection. The model pages break the same data down further — see Audi MOT pass rates by model.

Limitations

Official data: DVSA anonymised MOT results (2023–2024). 73 Auto analysis: expected failures apply the national rate of each item for the test's age, mileage band and fuel. MOT results reflect maintenance and use as well as design; they do not rank makes by reliability.
