55246587 MJD 8F3.F6 – 1.3 Multijet engine ECU
Part number 55246587 identifies a Magneti Marelli MJD 8F3.F6 ECU for the Fiat Fiorino 1.3 Multijet. Before shipping, we check it on the bench and in our test car.
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.
Part number and ECU type
The part number on the label is what matters most when ordering:
- Part number: 55246587
- ECU type: Magneti Marelli MJD 8F3.F6 / MJD8F3.F6
Coding to the immobiliser
- Virgin: the ECU codes itself after fitting – no programming, with a matching part number and a working immobiliser.
- IMMO OFF (on request): the car drives, but a red immobiliser warning is shown on the dashboard and a fault stays in diagnostics that cannot be cleared without pairing with the immobiliser.
- We recommend Virgin, as it leaves no fault.
Preparation before dispatch
- Bench test.
- Fitting and check in our test car.
- On request, for an extra charge: EGR OFF and DPF OFF.
Warranty on the ECU: 6 months.
