Diesel against the other Mercedes-Benz Citan versions
| Fuel | Pass rate | Tests |
|---|---|---|
| Diesel | 69.5% | 17,745 |
| Petrol | 88.8% | 321 |
| All Mercedes-Benz Citan | 69.8% | 18,066 |
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 Mercedes-Benz Citan specifically, petrol is the strongest at 88.8%, and this diesel version sits 0.3 points below the 69.8% 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 Mercedes-Benz Citan had covered 103,275 miles at test, against 51,218 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 Mercedes-Benz Citan page separate age from fuel if you want to isolate one.
