The Audi A5 was MOT tested 264,862 times in 2024 (DVSA data, retests included) across 15 model years (2007 to 2021), with an average pass rate of 86%. That's slightly above the average of 82% across all models in our data. Our records list diesel versions.

Best and Worst Years

Of the years with at least 100 tests, the 2021 model has the highest pass rate at 92% from 768 tests. The 2007 model has the lowest at 82%. The 10 point gap means pass rates vary somewhat between years, but no year is dramatically different. Newer cars usually pass more often simply because they are younger.

Reliability Trend

Newer Audi A5s pass their MOT more often than older ones, by 6 percentage points on average, which is mostly down to age and wear.

Mileage Across Years

The oldest model in our data (2007) averages 141,630 miles, while the newest (2021) averages 29,053 miles. Older models have covered serious mileage, so suspension and drivetrain wear are worth checking.

Compared to the Audi brand average of 90%, the A5 is 4 points lower, placing it among the less reliable Audi models.
