Diesel against the other Kia Soul versions
| Fuel | Pass rate | Tests |
|---|---|---|
| Diesel | 72.4% | 14,417 |

| Electric | 86.5% | 896 |

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 Kia Soul specifically, electric is the strongest at 86.5%, and this diesel version sits 1.6 points below the 74% model average.
What it means if you are buying one
The diesel Kia Soul 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 Kia Soul had covered 77,601 miles at test, against 66,100 for the petrol and 45,234 for the electric. 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 Kia Soul page separate age from fuel if you want to isolate one.
