Diesel against the other BMW X6 versions
| Fuel | Pass rate | Tests |
|---|---|---|
| Diesel | 84.8% | 12,869 |
| Petrol | 85.8% | 513 |
| All BMW X6 | 84.9% | 13,384 |
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 X6 specifically, petrol is the strongest at 85.8%, and this diesel version sits 0.1 points below the 84.9% 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 X6 had covered 86,394 miles at test, against 61,275 for the petrol. That is above average, the point where suspension bushes, drop links and exhaust corrosion start showing up as advisories before they become failures.
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 X6 page separate age from fuel if you want to isolate one.
