Diesel against the other BMW 740 versions
| Fuel | Pass rate | Tests |
|---|---|---|
| Diesel | 89.7% | 2,111 |
| Petrol | 86.7% | 1,004 |
| All BMW 740 | 88.7% | 3,132 |
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 740 specifically, diesel is the strongest at 89.7%, and this diesel version sits 1 points above the 88.7% model average.
What it means if you are buying one
The diesel BMW 740 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 diesel BMW 740 had covered 73,491 miles at test, against 89,764 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 740 page separate age from fuel if you want to isolate one.
