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 MINI MINI specifically, diesel is the strongest at 74.3%, and this diesel version sits 5.1 points above the 69.2% model average.

What it means if you are buying one

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