Why the fuel type changes the number

Petrol cars avoid the DPF and emissions failures that catch diesels, and usually fail on the same consumables as any other car.

On the BMW X4 specifically, petrol is the strongest at 90.8%, and this petrol version sits 4.2 points above the 86.6% model average.

What it means if you are buying one

The petrol BMW X4 is the stronger side of this model on MOT data. Still judge the individual car, but the fuel type is a mild point in its favour. Check the exact car, decode the VIN and check the mileage before you bid.

Mileage is part of the answer

The average petrol BMW X4 had covered 34,881 miles at test, against 63,193 for the diesel. That is below average for a car this age, worth a mileage-consistency check since an unusually low reading is sometimes clocking rather than luck.

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 BMW X4 page separate age from fuel if you want to isolate one.
