Diesel against the other Skoda Superb 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 Superb specifically, petrol is the strongest at 85.4%, and this diesel version sits 1.3 points below the 80.4% model average.

What it means if you are buying one

The diesel Skoda Superb 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 Superb had covered 110,297 miles at test, against 59,663 for the petrol. That is high mileage, so timing belts, clutches, suspension bushes and corrosion are the items worth budgeting for rather than the MOT itself.

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