How the Audi A4 holds up with age
Every car fails the MOT more often as it gets older. What matters when you are buying is how steeply that happens for this particular model. These are the 2025 pass rates for the Audi A4 grouped by the vehicle's age at the time of the test.
| Age at test | Tests | Pass rate |
|---|---|---|
| 3–5 years | 17,604 | 89.01% |
| 6–10 years | 85,106 | 81.37% |
| 11 years and over | 135,256 | 72.8% |
The Audi A4 drops 16.2 percentage points between its early years and the 11-plus bracket, which is a steep decline. On an older example, the MOT history is worth reading closely before you buy.

What this means when buying a used Audi A4
A pass rate is a population average, not a verdict on the specific car in front of you. The average Audi A4 came to its 2025 test at 107,016 miles and 12.1 years old. Most examples tested were diesel.
The useful check is the individual car's own MOT record: how many times it has failed, what for, and whether advisories keep reappearing. A recurring advisory on corrosion, suspension or brakes tells you far more than a model-wide average, and a mileage that does not move consistently between tests is a warning in itself.
