Diesel against the other Kia Venga versions

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 Venga specifically, petrol is the strongest at 81.3%, and this diesel version sits 8.2 points below the 78.6% model average.

What it means if you are buying one

The diesel Kia Venga 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. 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 diesel Kia Venga had covered 76,050 miles at test, against 49,825 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 Kia Venga page separate age from fuel if you want to isolate one.
