Diesel Fiat Ducato: MOT pass rate

75.9% of diesel Fiat Ducatos pass the MOT first time, measured across 89,451 DVSA tests on that fuel type alone. Average mileage at test was 71,293.

Diesel against the other Fiat Ducato 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 Fiat Ducato specifically, diesel is the strongest at 75.9%, and this diesel version sits 0.2 points above the 75.7% 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 Fiat Ducato had covered 71,293 miles at test, against 77,003 for the petrol. That is a shade above the middle of the range, still ordinary wear rather than a red flag, but worth checking against the service book for the car's age.

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 Fiat Ducato page separate age from fuel if you want to isolate one.

3. Parking brake efficiency less than 50% of the required value, 1.6% of tests (4.28x the national rate for this defect)
4. Parking brake efficiency below minimum requirement, 3.7% of tests (2.83x the national rate for this defect)
5. Significant brake effort recorded with no brake applied indicating a binding brake, 2.7% of tests (2.59x the national rate for this defect)
6. A direction indicator lamp missing, inoperative or in the case of a multiple light source more than 1/2 not functioning, 1.6% of tests (2.51x the national rate for this defect)
7. A lamp missing, inoperative or in the case of a multiple light source more than 1/2 not functioning, 4.5% of tests (2.02x the national rate for this defect)

From 90,168 DVSA-tracked diesel Fiat Ducato tests, 2024, split out from the Fiat Ducato's other fuel types. DVSA testers marked 3.67% of these flagged defects as "dangerous", against 5.11% nationally.
