Diesel Citroen C2: MOT pass rate

58.2% of diesel Citroen C2s pass the MOT first time, measured across 1,541 DVSA tests on that fuel type alone. Average mileage at test was 105,411.

Diesel against the other Citroen C2 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 C2 specifically, petrol is the strongest at 61%, and this diesel version sits 2.4 points below the 60.6% model average.

What it means if you are buying one

The diesel Citroen C2 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 C2 had covered 105,411 miles at test, against 80,791 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 C2 page separate age from fuel if you want to isolate one.

Most common MOT failures on a diesel Citroen C2

1. The strength or continuity of the load bearing structure within 30cm of any seat belt anchorage (a 'prescribed area') is significantly reduced or inadequately repaired, 4.7% of tests (17.54x the national rate for this defect)
2. The strength or continuity of the load bearing structure within 30cm of any sub-frame, spring or suspension component mounting (a 'prescribed area') is significantly reduced or inadequately repaired, 11.1% of tests (11.76x the national rate for this defect)
3. Vehicle structure corroded to the extent that the rigidity of the assembly is seriously reduced, 3.9% of tests (9.47x the national rate for this defect)
4. Lamp emitted colour, position or intensity not in accordance with the requirements, 4.6% of tests (7.65x the national rate for this defect)
5. A transmission shaft constant velocity joint boot missing or no longer prevents the ingress of dirt etc, 7.6% of tests (4.95x the national rate for this defect)
6. Exhaust system leaking or insecure, 4.9% of tests (4.82x the national rate for this defect)
7. Significant brake effort recorded with no brake applied indicating a binding brake, 4.4% of tests (4.21x the national rate for this defect)
8. Stop lamp missing, inoperative or in the case of a multiple light source more than 1/2 not functioning, 4.4% of tests (3.21x the national rate for this defect)

From 1,558 DVSA-tracked diesel Citroen C2 tests, 2024, split out from the Citroen C2's other fuel types. DVSA testers marked 3.75% of these flagged defects as "dangerous", against 5.11% nationally.
