Diesel against the other BMW X7 versions
| Fuel | Pass rate | Tests |
|---|---|---|
| Diesel | 85.1% | 872 |
| Petrol | 86.3% | 278 |
| All BMW X7 | 85.4% | 1,153 |
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 X7 specifically, petrol is the strongest at 86.3%, and this diesel version sits 0.3 points below the 85.4% 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 X7 had covered 45,123 miles at test, against 37,135 for the petrol. 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 X7 page separate age from fuel if you want to isolate one.
