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 Volkswagen T-Roc specifically, petrol is the strongest at 92.8%, and this diesel version sits 0.7 points below the 92.5% 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. Check the exact car, decode the VIN and check the mileage before you bid.

Mileage is part of the answer

The average diesel Volkswagen T-Roc had covered 44,184 miles at test, against 36,319 for the petrol. That is below average for a car this age, worth a mileage-consistency check since an unusually low reading is sometimes clocking rather than luck.

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 Volkswagen T-Roc page separate age from fuel if you want to isolate one.
