Diesel Ford Transit Connect: MOT pass rate
72.5% of diesel Ford Transit Connects pass the MOT first time, measured across 165,797 DVSA tests on that fuel type alone. Average mileage at test was 104,377.
Diesel against the other Ford Transit Connect versions
| Fuel | Pass rate | Tests |
|---|---|---|
| Diesel | 72.5% | 165,797 |
| Petrol | 79.2% | 1,955 |
| All Ford Transit Connect | 72.6% | 167,884 |
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 Ford Transit Connect specifically, petrol is the strongest at 79.2%, and this diesel version sits 0.1 points below the 72.6% 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 Ford Transit Connect had covered 104,377 miles at test, against 67,395 for the petrol. That is above average and into the range where cambelts and water pumps are due if they have not already been done, so ask for the service history rather than take the mileage on trust.
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 Ford Transit Connect page separate age from fuel if you want to isolate one.
Most common MOT failures on a diesel Ford Transit Connect
- Vehicle structure corroded to the extent that the rigidity of the assembly is seriously reduced, 2.5% of tests (5.96x the national rate for this defect)
- 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, 4.9% of tests (5.14x the national rate for this defect)
- Brake pipe damaged or excessively corroded, 3.1% of tests (2.9x the national rate for this defect)
- A transmission shaft constant velocity joint boot missing or no longer prevents the ingress of dirt etc, 3.4% of tests (2.23x the national rate for this defect)
- Parking brake efficiency below minimum requirement, 2.5% of tests (1.91x the national rate for this defect)
- Wiper blade missing or obviously not clearing the windscreen, 3.6% of tests (1.88x the national rate for this defect)
- 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)
- a brake lining or pad worn below 1.5mm, 3.7% of tests (1.74x the national rate for this defect)
- A tyre cords visible or damaged, 2.8% of tests (1.7x the national rate for this defect)

From 166,971 DVSA-tracked diesel Ford Transit Connect tests, 2024, split out from the Ford Transit Connect's other fuel types. DVSA testers marked 5.8% of these flagged defects as "dangerous", against 5.11% nationally.
