Petrol Rover 45: MOT pass rate

62.9% of petrol Rover 45s pass the MOT first time, measured across 1,713 DVSA tests on that fuel type alone. Average mileage at test was 74,803.

Petrol against the other Rover 45 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 Rover 45 specifically, petrol is the strongest at 62.9%, and this petrol version sits 0.3 points above the 62.6% model average.

What it means if you are buying one

There is little to choose between fuel types on this model, so decide on running costs and mileage rather than MOT record. 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 Rover 45 had covered 74,803 miles at test, against 105,303 for the diesel. That is a shade above the middle of the range, still ordinary wear rather than a red flag, but worth checking against the service book for the car's age.

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 Rover 45 page separate age from fuel if you want to isolate one.

Most common MOT failures on a petrol Rover 45

1. The strength or continuity of the load bearing structure within 30cm of any sub-frame, spring or suspension component mounting (a 'prescribed area') is significantly reduced or inadequately repaired, 17.4% of tests (18.4x the national rate for this defect)
2. Vehicle structure corroded to the extent that the rigidity of the assembly is seriously reduced, 3.7% of tests (8.97x the national rate for this defect)
3. An SRS malfunction indicator lamp (MIL) indicates a system malfunction, 2.8% of tests (6.84x the national rate for this defect)
4. A transmission shaft constant velocity joint boot missing or no longer prevents the ingress of dirt etc, 8.6% of tests (5.63x the national rate for this defect)
5. Significant brake effort recorded with no brake applied indicating a binding brake, 4.5% of tests (4.35x the national rate for this defect)
6. Exhaust system leaking or insecure, 4.4% of tests (4.35x the national rate for this defect)
7. Brake pipe damaged or excessively corroded, 3.1% of tests (2.93x the national rate for this defect)
8. Stop lamp missing, inoperative or in the case of a multiple light source more than 1/2 not functioning, 3.1% of tests (2.3x the national rate for this defect)
9. Parking brake efficiency below minimum requirement, 2.5% of tests (1.96x the national rate for this defect)
10. Wiper blade missing or obviously not clearing the windscreen, 3.6% of tests (1.89x the national rate for this defect)

From 1,727 DVSA-tracked petrol Rover 45 tests, 2024, split out from the Rover 45's other fuel types. DVSA testers marked 3.07% of these flagged defects as "dangerous", against 5.11% nationally.
