Diesel Mitsubishi Outlander: MOT pass rate

71.5% of diesel Mitsubishi Outlanders pass the MOT first time, measured across 19,649 DVSA tests on that fuel type alone. Average mileage at test was 99,713.

Diesel against the other Mitsubishi Outlander 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 Mitsubishi Outlander specifically, hybrid is the strongest at 85.2%, and this diesel version sits 9.2 points below the 80.7% model average.

What it means if you are buying one

The diesel Mitsubishi Outlander 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 Mitsubishi Outlander had covered 99,713 miles at test, against 78,538 for the hybrid and 98,332 for the electric and 64,946 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 Mitsubishi Outlander page separate age from fuel if you want to isolate one.
