Diesel Kia Ceed: MOT pass rate

70.1% of diesel Kia Ceeds pass the MOT first time, measured across 70,424 DVSA tests on that fuel type alone. Average mileage at test was 90,124.

Diesel against the other Kia Ceed 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 Ceed specifically, petrol is the strongest at 75%, and this diesel version sits 1.8 points below the 71.9% model average.

What it means if you are buying one

The diesel Kia Ceed 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 Ceed had covered 90,124 miles at test, against 67,966 for the petrol. That is above average, the point where suspension bushes, drop links and exhaust corrosion start showing up as advisories before they become failures.

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 Ceed page separate age from fuel if you want to isolate one.
