Petrol against the other Audi A4 versions
| Fuel | Pass rate | Tests |
|---|---|---|

| Petrol | 80.6% | 79,295 |
| All Audi A4 | 76.8% | 244,401 |
Why the fuel type changes the number
Petrol cars avoid the DPF and emissions failures that catch diesels, and usually fail on the same consumables as any other car.
On the Audi A4 specifically, petrol is the strongest at 80.6%, and this petrol version sits 3.8 points above the 76.8% model average.
What it means if you are buying one
The petrol Audi A4 is the stronger side of this model on MOT data. Still judge the individual car, but the fuel type is a mild point in its favour. Check the exact car, decode the VIN and check the mileage before you bid.
Mileage is part of the answer
The average petrol Audi A4 had covered 80,740 miles at test, against 121,863 for the diesel. That is above average, the point where suspension bushes, drop links and exhaust corrosion start showing up as advisories before they become failures.
Fuel type and mileage are tangled together: diesels are usually bought by higher-mileage drivers, so some of any gap between fuels is the miles rather than the engine. The per-year figures on the Audi A4 page separate age from fuel if you want to isolate one.
