Petrol against the other BMW 1 Series versions
| Fuel | Pass rate | Tests |
|---|---|---|
| Petrol | 85.8% | 45,358 |
| Diesel | 77.1% | 34,660 |
| All BMW 1 Series | 82% | 80,022 |
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 1 Series specifically, petrol is the strongest at 85.8%, and this petrol version sits 3.8 points above the 82% model average.
What it means if you are buying one
The petrol BMW 1 Series is the stronger side of this model on MOT data. Still judge the individual car, but the fuel type is a mild point in its favour. Check the exact car, decode the VIN and check the mileage before you bid.
Mileage is part of the answer
The average petrol BMW 1 Series had covered 59,339 miles at test, against 96,777 for the diesel. That is around average, so condition and service history will tell you more than the odometer does.
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 1 Series page separate age from fuel if you want to isolate one.
