Engine ECU 51872449 (MJD8F2.I2) – description
On this page you can buy ECU 51872449, a Magneti Marelli MJD 8F2.I2 unit intended for the Lancia Musa 1.3 Multijet. It goes through a function test before dispatch.
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.
Virgin version – no programming
We ship ECU 51872449 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.
Numbers on the label
- Part number: 51872449
- ECU type: Magneti Marelli MJD 8F2.I2 / MJD8F2.I2
What we check before dispatch
We first test ECU 51872449 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.
How to check compatibility
This unit comes from a Lancia Musa 1.3 Multijet. The safest way is to compare labels: part number 51872449 and marking MJD 8F2.I2 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.
