Petrol MINI MINI: MOT pass rate

68.2% of petrol MINI MINIs pass the MOT first time, measured across 214,900 DVSA tests on that fuel type alone. Average mileage at test was 88,582.

Petrol against the other MINI MINI versions

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 MINI MINI specifically, diesel is the strongest at 74.3%, and this petrol version sits 1 points below the 69.2% model average.

What it means if you are buying one

The petrol MINI MINI fails more often than the model average, so budget for the items that catch this fuel type and treat a fresh MOT as worth paying for. Buying a damaged one? run it through the analyzer, check the exact car, decode the VIN and check the mileage before you bid.

Mileage is part of the answer

The average petrol MINI MINI had covered 88,582 miles at test, against 102,737 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 MINI MINI page separate age from fuel if you want to isolate one.

4. Brake pipe damaged or excessively corroded, 3.4% of tests (3.18x the national rate for this defect)
5. The aim of a headlamp is not within limits laid down in the requirements, 6.6% of tests (2.79x the national rate for this defect)
6. A lamp missing, inoperative or in the case of a multiple light source more than 1/2 not functioning, 6.1% of tests (2.73x the national rate for this defect)
7. Significant brake effort recorded with no brake applied indicating a binding brake, 2.4% of tests (2.31x the national rate for this defect)
8. Exhaust system leaking or insecure, 2.3% of tests (2.27x the national rate for this defect)
9. Engine MIL illuminated indicating a malfunction, 2.5% of tests (1.95x the national rate for this defect)

From 219,268 DVSA-tracked petrol MINI MINI tests, 2024, split out from the MINI MINI's other fuel types. DVSA testers marked 3.28% of these flagged defects as "dangerous", against 5.11% nationally.

Most common MOT advisories on a petrol MINI MINI

Flagged but doesn't fail the car, a different list from the failures above.
