70.6% of diesel Toyota Hiaces pass the MOT first time, measured across 6,126 DVSA tests on that fuel type alone. Average mileage at test was 152,144.

Diesel against the other Toyota Hiace 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 Toyota Hiace specifically, petrol is the strongest at 79.2%, and this diesel version sits 0.7 points below the 71.3% 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 Toyota Hiace had covered 152,144 miles at test, against 96,716 for the petrol. That is very high mileage. Clutches, dual-mass flywheels and head gaskets have usually been through at least one repair by this point, so ask for evidence rather than assume the car is original everywhere.

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