Diesel against the other MINI Countryman 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 MINI Countryman specifically, petrol is the strongest at 90.5%, and this diesel version sits 2.6 points below the 89.4% model average.

What it means if you are buying one

The diesel MINI Countryman 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 MINI Countryman had covered 65,939 miles at test, against 40,074 for the petrol and 47,426 for the hybrid. That is a shade above the middle of the range, still ordinary wear rather than a red flag, but worth checking against the service book for the car's age.

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