What the MOT tests show

What we know

2.6 fails per 100 MOT tests at 17 years, against 6.5 for all class 4 vehicles tested at 17 (all test years). The Fiat Ducato fails less often here.

Why it matters

An exhaust, emissions and leaks fail stops the car passing until it is fixed; the most common one is rated major by DVSA.

What to check

Start the car from cold and look for smoke at the exhaust, listen for blowing joints, and look under the engine and gearbox for fresh oil or fluid drips.

The Fiat Ducato is a commercial or van-based vehicle: it is compared with all class 4 vehicles, cars and vans together, so part of any difference can come from how vans are used.
