Diesel Vauxhall Corsa: MOT pass rate
67.2% of diesel Vauxhall Corsas pass the MOT first time, measured across 69,438 DVSA tests on that fuel type alone. Average mileage at test was 100,768.
Diesel against the other Vauxhall Corsa versions
| Fuel | Pass rate | Tests |
|---|---|---|
| Petrol | 70.7% | 755,988 |
| Diesel | 67.2% | 69,438 |
| All Vauxhall Corsa | 70.4% | 825,490 |
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 Vauxhall Corsa specifically, petrol is the strongest at 70.7%, and this diesel version sits 3.2 points below the 70.4% model average.
What it means if you are buying one
The diesel Vauxhall Corsa 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 Vauxhall Corsa had covered 100,768 miles at test, against 67,068 for the petrol. That is above average and into the range where cambelts and water pumps are due if they have not already been done, so ask for the service history rather than take the mileage on trust.
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 Vauxhall Corsa page separate age from fuel if you want to isolate one.
