Diesel against the other Citroen C1 versions
| Fuel | Pass rate | Tests |
|---|---|---|
| Petrol | 75.6% | 163,316 |
| Diesel | 62% | 1,054 |
| All Citroen C1 | 75.5% | 164,400 |
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 C1 specifically, petrol is the strongest at 75.6%, and this diesel version sits 13.5 points below the 75.5% model average.
What it means if you are buying one
The diesel Citroen C1 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 Citroen C1 had covered 101,349 miles at test, against 63,498 for the petrol. That is above average and into the range where cambelts and water pumps are due if they have not already been done, so ask for the service history rather than take the mileage on trust.
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 C1 page separate age from fuel if you want to isolate one.
