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 SEAT Ibiza specifically, petrol is the strongest at 72.5%, and this diesel version sits 7.7 points below the 71.7% model average.

What it means if you are buying one

The diesel SEAT Ibiza 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 SEAT Ibiza had covered 108,280 miles at test, against 67,542 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 SEAT Ibiza page separate age from fuel if you want to isolate one.
