Diesel Volkswagen T-Roc: MOT pass rate
91.8% of diesel Volkswagen T-Rocs pass the MOT first time, measured across 12,216 DVSA tests on that fuel type alone. Average mileage at test was 44,184.
Diesel against the other Volkswagen T-Roc versions
| Fuel | Pass rate | Tests |
|---|---|---|
| Petrol | 92.8% | 41,532 |
| Diesel | 91.8% | 12,216 |
| All Volkswagen T-Roc | 92.5% | 53,748 |
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. 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 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.
