Petrol against the other BMW 635 versions
| Fuel | Pass rate | Tests |
|---|---|---|
| Diesel | 78.1% | 1,509 |
| Petrol | 83.3% | 401 |
| All BMW 635 | 79.2% | 1,910 |
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 635 specifically, petrol is the strongest at 83.3%, and this petrol version sits 4.1 points above the 79.2% model average.
What it means if you are buying one
The petrol BMW 635 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 635 had covered 111,860 miles at test, against 126,017 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 635 page separate age from fuel if you want to isolate one.
