Diesel Rover 75: MOT pass rate

61.1% of diesel Rover 75s pass the MOT first time, measured across 4,445 DVSA tests on that fuel type alone. Average mileage at test was 121,693.

Diesel against the other Rover 75 versions

Why the fuel type changes the number

Diesels carry DPFs, EGR valves and stricter smoke limits, so emissions and exhaust faults account for failures petrol cars never see.

On the Rover 75 specifically, petrol is the strongest at 66.2%, and this diesel version sits 2.1 points below the 63.2% model average.

What it means if you are buying one

The diesel Rover 75 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 diesel Rover 75 had covered 121,693 miles at test, against 82,417 for the petrol. That is high mileage, so timing belts, clutches, suspension bushes and corrosion are the items worth budgeting for rather than the MOT itself.

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

Most common MOT failures on a diesel Rover 75

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, 11.8% of tests (12.48x the national rate for this defect)
2. A suspension component excessively damaged or corroded, 4.1% of tests (11.73x the national rate for this defect)
3. An SRS malfunction indicator lamp (MIL) indicates a system malfunction, 3.7% of tests (8.85x the national rate for this defect)
4. Vehicle structure corroded to the extent that the rigidity of the assembly is seriously reduced, 3.1% of tests (7.49x the national rate for this defect)
5. Lamp emitted colour, position or intensity not in accordance with the requirements, 3.2% of tests (5.42x the national rate for this defect)
6. Brake pipe damaged or excessively corroded, 4.9% of tests (4.58x the national rate for this defect)
7. Parking brake efficiency below minimum requirement, 5% of tests (3.83x the national rate for this defect)
8. The aim of a headlamp is not within limits laid down in the requirements, 8.7% of tests (3.7x the national rate for this defect)
9. A suspension joint dust cover missing or no longer prevents the ingress of dirt etc, 6.7% of tests (3.66x the national rate for this defect)
10. A suspension pin, bush or joint excessively worn, 17.6% of tests (3.51x the national rate for this defect)

From 4,490 DVSA-tracked diesel Rover 75 tests, 2024, split out from the Rover 75's other fuel types. DVSA testers marked 3.24% of these flagged defects as "dangerous", against 5.11% nationally.
