Petrol against the other BMW 640 versions
| Fuel | Pass rate | Tests |
|---|---|---|
| Diesel | 83.1% | 9,031 |
| Petrol | 86.7% | 933 |
| All BMW 640 | 83.4% | 9,964 |
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 640 specifically, petrol is the strongest at 86.7%, and this petrol version sits 3.3 points above the 83.4% model average.
What it means if you are buying one
The petrol BMW 640 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. Buying a damaged one? run it through the analyzer, check the exact car, decode the VIN and check the mileage before you bid.
Mileage is part of the answer
The average petrol BMW 640 had covered 62,444 miles at test, against 78,384 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 640 page separate age from fuel if you want to isolate one.
