How the TT compares

78.5%
Audi average
72.3%
UK average, all cars
The TT runs 1.7 points behind the Audi average. It is 20th of the 24 Audi models in the data. The average TT arrived at its test 13.4 years old with 80,292 miles recorded.
A pass rate records whether cars met the roadworthiness standard on test day. It is not a reliability score, and part of any gap reflects how old the tested cars were.
TT MOT pass rate by age
The same 2025 tests split by the car's age at test.
Audi TT cars aged 3 to 5 years passed 91.3% of MOT tests. For cars aged 11 years and over that fell to 69.5%, a drop of 21.8 percentage points.
| Age at test | Tests | Pass rate | vs UK average |
|---|---|---|---|
| 3 to 5 years | 9,114 | 91.3% | 19 pts above |
| 6 to 10 years | 32,077 | 87.1% | 14.8 pts above |
| 11 years and over | 68,314 | 69.5% | 2.8 pts below |
That is a steep decline with age, so the headline rate flatters older examples. The UK average of 72.3% covers cars of every age, so compare like with like.
