Diesel against the other BMW X5 versions
| Fuel | Pass rate | Tests |
|---|---|---|
| Diesel | 82.1% | 73,194 |
| Petrol | 77.5% | 6,512 |
| Hybrid | 86.4% | 1,840 |
| All BMW X5 | 81.8% | 81,696 |
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 BMW X5 specifically, hybrid is the strongest at 86.4%, and this diesel version sits 0.3 points above the 81.8% model average.
What it means if you are buying one
There is little to choose between fuel types on this model, so decide on running costs and mileage rather than MOT record. Check the exact car, decode the VIN and check the mileage before you bid.
Mileage is part of the answer
The average diesel BMW X5 had covered 99,419 miles at test, against 95,028 for the petrol and 68,722 for the hybrid. 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 BMW X5 page separate age from fuel if you want to isolate one.
