Diesel against the other Citroen C4 versions
| Fuel | Pass rate | Tests |
|---|---|---|
| Diesel | 65.7% | 101,823 |
| Petrol | 69.4% | 26,669 |
| All Citroen C4 | 66.5% | 128,506 |
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 Citroen C4 specifically, petrol is the strongest at 69.4%, and this diesel version sits 0.8 points below the 66.5% model average.
What it means if you are buying one
There is little to choose between fuel types on this model, so decide on running costs and mileage rather than MOT record. Check the exact car, decode the VIN and check the mileage before you bid.
Mileage is part of the answer
The average diesel Citroen C4 had covered 89,033 miles at test, against 70,384 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 Citroen C4 page separate age from fuel if you want to isolate one.
