Petrol against the other BMW 525 versions
| Fuel | Pass rate | Tests |
|---|---|---|
| Diesel | 76.8% | 9,806 |
| Petrol | 74.9% | 3,552 |
| All BMW 525 | 76.3% | 13,362 |
Why the fuel type changes the number
Petrol cars avoid the DPF and emissions failures that catch diesels, and usually fail on the same consumables as any other car.
On the BMW 525 specifically, diesel is the strongest at 76.8%, and this petrol version sits 1.4 points below the 76.3% model average.
What it means if you are buying one
The petrol BMW 525 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 petrol BMW 525 had covered 124,200 miles at test, against 146,139 for the diesel. That is high mileage, so timing belts, clutches, suspension bushes and corrosion are the items worth budgeting for rather than the MOT itself.
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 525 page separate age from fuel if you want to isolate one.
