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 (R57) specifically, diesel is the strongest at 77.9%, and this diesel version sits 0.6 points above the 77.3% 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. 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 (R57) had covered 88,275 miles at test, against 65,237 for the petrol. 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 (R57) page separate age from fuel if you want to isolate one.
