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 Fiat Fiorino specifically, petrol is the strongest at 80.6%, and this diesel version sits 1 points below the 67.7% model average.

What it means if you are buying one

The diesel Fiat Fiorino 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 Fiat Fiorino had covered 99,991 miles at test, against 55,651 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 Fiat Fiorino page separate age from fuel if you want to isolate one.
