Diesel against the other Ford Ka versions
| Fuel | Pass rate | Tests |
|---|---|---|

| Diesel | 60.1% | 2,212 |
| All Ford Ka | 72.7% | 180,034 |
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 Ford Ka specifically, petrol is the strongest at 72.8%, and this diesel version sits 12.6 points below the 72.7% model average.
What it means if you are buying one
The diesel Ford Ka 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 Ford Ka had covered 88,999 miles at test, against 56,305 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 Ford Ka page separate age from fuel if you want to isolate one.
