Diesel Ford Fusion: MOT pass rate

65.3% of diesel Ford Fusions pass the MOT first time, measured across 12,068 DVSA tests on that fuel type alone. Average mileage at test was 103,165.

Diesel against the other Ford Fusion 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 Ford Fusion specifically, petrol is the strongest at 69.3%, and this diesel version sits 3.1 points below the 68.4% model average.

What it means if you are buying one

The diesel Ford Fusion 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 Ford Fusion had covered 103,165 miles at test, against 83,653 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 Ford Fusion page separate age from fuel if you want to isolate one.
