Diesel against the other MINI MINI (R58) versions
| Fuel | Pass rate | Tests |
|---|---|---|

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 (R58) specifically, petrol is the strongest at 78.6%, and this diesel version sits 1.7 points below the 78.1% model average.
What it means if you are buying one
The diesel MINI MINI (R58) 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. 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 (R58) had covered 92,623 miles at test, against 69,824 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 (R58) page separate age from fuel if you want to isolate one.
