Diesel Toyota Granvia: MOT pass rate

70% of diesel Toyota Granvias pass the MOT first time, measured across 819 DVSA tests on that fuel type alone. Average mileage at test was 147,438.

Diesel against the other Toyota Granvia 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 Granvia specifically, petrol is the strongest at 71%, and this diesel version sits 0.4 points below the 70.4% 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 Granvia had covered 147,438 miles at test, against 106,631 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 Granvia page separate age from fuel if you want to isolate one.

1. A flexible brake hose excessively damaged, deteriorated, chafed, twisted or stretched, 2.8% of tests (30.01x the national rate for this defect)
2. An obligatory rear fog lamp missing, or a front or rear fog lamp inoperative or in the case of a multiple light source more than 1/2 not functioning, 8% of tests (18.21x the national rate for this defect)
3. The strength or continuity of the load bearing structure within 30cm of any seat belt anchorage (a 'prescribed area') is significantly reduced or inadequately repaired, 3.4% of tests (12.72x the national rate for this defect)
4. Vehicle structure corroded to the extent that the rigidity of the assembly is seriously reduced, 4.6% of tests (11.16x the national rate for this defect)
5. 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, 7% of tests (7.46x the national rate for this defect)
6. Brake pipe damaged or excessively corroded, 6.6% of tests (6.13x the national rate for this defect)
7. Exhaust system leaking or insecure, 4.5% of tests (4.44x the national rate for this defect)

9. Stop lamp missing, inoperative or in the case of a multiple light source more than 1/2 not functioning, 2.5% of tests (1.87x the national rate for this defect)
10. A transmission shaft constant velocity joint boot missing or no longer prevents the ingress of dirt etc, 2.8% of tests (1.82x the national rate for this defect)

From 824 DVSA-tracked diesel Toyota Granvia tests, 2024, split out from the Toyota Granvia's other fuel types. DVSA testers marked 2.52% of these flagged defects as "dangerous", against 5.11% nationally.
