Diesel against the other BMW 225 versions
| Fuel | Pass rate | Tests |
|---|---|---|
| Hybrid | 86.7% | 1,298 |
| Diesel | 83.4% | 823 |
| Petrol | 90% | 399 |
| All BMW 225 | 86.2% | 2,522 |
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 225 specifically, petrol is the strongest at 90%, and this diesel version sits 2.8 points below the 86.2% model average.
What it means if you are buying one
The diesel BMW 225 fails more often than the model average, so budget for the items that catch this fuel type and treat a fresh MOT as worth paying for. Check the exact car, decode the VIN and check the mileage before you bid.
Mileage is part of the answer
The average diesel BMW 225 had covered 67,706 miles at test, against 64,594 for the hybrid and 48,256 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 225 page separate age from fuel if you want to isolate one.
