ECU 51880758 – what to know
We offer a working MJD 8F2.G4 unit (Magneti Marelli) with part number 51880758. It controls the engine of the Fiat Punto 1.3 Multijet. We test every unit before dispatch.
When the ECU may be faulty
An engine ECU failure may show up as:
- no start and no signal at the injectors,
- the diagnostic tool cannot connect to the ECU,
- the ECU gets no power even though the fuses are OK,
- problems after water damage or a short in the wiring.
Faults in the wiring, power supply or sensors can cause similar symptoms, so run a diagnosis before you buy.
What we check before dispatch
We first test ECU 51880758 on the bench and then fit it to our test car. Only a working unit is shipped. For an extra charge we carry out EGR OFF and DPF OFF. The warranty is 6 months.
Vehicle compatibility
This ECU was removed from a Fiat Punto 1.3 Multijet. Compatibility is decided by the part number on the label, not just by the model and year – compare number 51880758 and marking MJD 8F2.G4 with your ECU. A different part number means a different ECU version.

Coding to the immobiliser
- Virgin: the ECU codes itself after fitting – no programming, with a matching part number and a working immobiliser.
