Diesel against the other Citroen C4 Cactus 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 Citroen C4 Cactus specifically, petrol is the strongest at 81%, and this diesel version sits 4 points below the 79.6% model average.

What it means if you are buying one

The diesel Citroen C4 Cactus 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 Citroen C4 Cactus had covered 58,972 miles at test, against 43,003 for the petrol. That is around average, so condition and service history will tell you more than the odometer does.

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