Diesel Toyota Hi-Ace: MOT pass rate

73% of diesel Toyota Hi-Aces pass the MOT first time, measured across 7,310 DVSA tests on that fuel type alone. Average mileage at test was 149,317.

Diesel against the other Toyota Hi-Ace 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 Hi-Ace specifically, petrol is the strongest at 73.1%, and this diesel version sits 0.1 points above the 72.9% 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 Hi-Ace had covered 149,317 miles at test, against 125,525 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 Hi-Ace page separate age from fuel if you want to isolate one.

Most common MOT failures on a diesel Toyota Hi-Ace

2. Body, cab or chassis excessively corroded at a mounting point, 2.5% of tests (10.73x the national rate for this defect)
3. The strength or continuity of the load bearing structure within 30cm of any sub-frame, spring or suspension component mounting (a 'prescribed area') is significantly reduced or inadequately repaired, 9.9% of tests (10.5x the national rate for this defect)
4. A shock absorber bush excessively worn, 1.5% of tests (7.66x the national rate for this defect)
5. Smoke opacity levels exceed the manufacturer's specified limit, 1.5% of tests (5.72x the national rate for this defect)
6. Brake pipe damaged or excessively corroded, 4.9% of tests (4.55x the national rate for this defect)
7. Wiper blade missing or obviously not clearing the windscreen, 4.2% of tests (2.2x the national rate for this defect)

From 7,366 DVSA-tracked diesel Toyota Hi-Ace tests, 2024, split out from the Toyota Hi-Ace's other fuel types. DVSA testers marked 2.76% of these flagged defects as "dangerous", against 5.11% nationally.
