Diesel against the other Volvo Xc40 versions
| Fuel | Pass rate | Tests |
|---|---|---|
| Petrol | 91.3% | 37,428 |
| Diesel | 89.6% | 11,433 |
| All Volvo Xc40 | 90.9% | 48,917 |
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 Volvo Xc40 specifically, petrol is the strongest at 91.3%, and this diesel version sits 1.3 points below the 90.9% model average.
What it means if you are buying one
The diesel Volvo Xc40 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 diesel Volvo Xc40 had covered 48,716 miles at test, against 31,959 for the petrol. That is below average for a car this age, worth a mileage-consistency check since an unusually low reading is sometimes clocking rather than luck.
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 Volvo Xc40 page separate age from fuel if you want to isolate one.
