How to choose ECU 55250632 MJD 8F3.Q1
This is a working Magneti Marelli MJD 8F3.Q1 engine control unit with part number 55250632, for the Fiat Qubo / Fiorino 1.3 Multijet. The unit is tested before dispatch.
Virgin version – no programming
We ship ECU 55250632 as Virgin. After fitting, it codes itself to the car and immobiliser – no programming is needed, as long as the part number matches and the immobiliser works.
On request we prepare an IMMO OFF version. The car will drive, but a red immobiliser warning stays on the dashboard and a fault remains in diagnostics that you cannot clear without pairing with the immobiliser. That is why we recommend Virgin.
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.
How to check compatibility
This is an ECU for the Fiat Qubo / Fiorino 1.3 Multijet. The safest way is to compare labels: part number 55250632 and marking MJD 8F3.Q1 must be the same as on your ECU. If the number differs, it is a different version – look for your number in the category or ask us.
Symptoms that may point to an ECU failure
- Diagnostics cannot connect to the ECU.
- The engine will not fire, the injectors get no signal.
- The fault appeared after water got in or after a short in the harness.
- The ECU has no power despite working fuses.
The cause may also be the wiring, the power supply or a sensor. Diagnose first, then buy.
