Other Faults on This Variant
EGR Valve Failure
ModerateEGR failure is the most common fault reported on the Punto Mk3 1.3 Multijet. The small diesel's EGR valve blocks with carbon rapidly in urban use.
Clutch Actuator Failure (Dualogic)
SevereFiat's Dualogic semi-automatic gearbox uses an electric clutch actuator that fails with age. When it does, the car refuses to pull away — an expensive repair relative to the car's value.
Rear Arch and Sill Corrosion
ModerateThe Punto Mk3 has a poor reputation for bodywork corrosion in the UK. Rear wheel arch lips and sill box sections corrode, often failing MOT on older examples.
