Diesel against the other BMW 330 versions
| Fuel | Pass rate | Tests |
|---|---|---|
| Hybrid | 87.5% | 15,787 |
| Diesel | 88.4% | 4,418 |
| Petrol | 88.3% | 648 |
| All BMW 330 | 87.7% | 20,855 |
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 330 specifically, diesel is the strongest at 88.4%, and this diesel version sits 0.7 points above the 87.7% 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 330 had covered 69,704 miles at test, against 63,536 for the hybrid and 61,346 for the petrol. That is a shade above the middle of the range, still ordinary wear rather than a red flag, but worth checking against the service book for the car's age.
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 330 page separate age from fuel if you want to isolate one.
