Diesel against the other Citroen C4 Grand Picasso 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 Grand Picasso specifically, petrol is the strongest at 78.2%, and this diesel version sits 0.4 points below the 73.7% 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. 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 Grand Picasso had covered 66,937 miles at test, against 52,107 for the petrol. That is a shade above the middle of the range, still ordinary wear rather than a red flag, but worth checking against the service book for the car's age.

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