Fiat Punto ECU malfunction

Fiat Punto ECU

1.2 litre Year 2000 - onwards

ECU Type - Magneti Marelli IAW 59F

ECU location: Fitted to the back of the throttle housing

These Punto ECU’s are failing in huge numbers causing the engine to misfire on two cylinders. The fault is originally caused by the ignition coil spiking back to the ECU and blowing the coil drivers inside the ECU.

When the ECU is changed or refitted after rebuild the coils should be replaced at the same time to avoid any possible damage to the replacement/remanufactured ECU.

We have two options to resolve these issues – rebuild of your own unit or a replacement ECU, both options require no programming after installing to the vehicle.
