Numbers to compare with your label
The housing of the original ECU carries a sticker with its numbers. On this unit they are:
- Part number: 51806500
- ECU type: Magneti Marelli MJD 6F3.Y3 / MJD6F3.Y3
Virgin version – no programming
We ship ECU 51806500 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.
Choose by part number
This unit comes from a Lancia Ypsilon 1.3 Multijet. We match these ECUs by part number only, because the version is decided by the number, not by the MJD 6F3.Y3 type alone. Number 51806500 on your label must match the number of this unit.
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.
If your ECU has a different part number, check 51805375 MJD 6F3.Y1, 51784559 MJD 6F3.M3, 51854484 MJD 6F3.M5, 51812864 MJD 6F3.Y3 or the whole Lancia engine ECU category. About the manufacturer: FPT.
