Diesel against the other Skoda Roomster 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 Skoda Roomster specifically, petrol is the strongest at 75.4%, and this diesel version sits 7 points below the 71.1% model average.

What it means if you are buying one

The diesel Skoda Roomster 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 Skoda Roomster had covered 107,565 miles at test, against 75,371 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 Skoda Roomster page separate age from fuel if you want to isolate one.
