What you get when you buy 52059433
Preparation for the vehicle
ECU 52059433 is prepared as Virgin Plug & Play, so after fitting it codes itself to the vehicle and immobiliser (with matching numbers and a working immobiliser). An IMMO OFF version is also possible – the vehicle drives, but with an immobiliser fault and a red warning light that only immobiliser programming removes.
How to choose the ECU
Compare the part number and marking with the label on your ECU – they must match:
- Part number: 52059433
- ECU type: Magneti Marelli MJD 9DF.A1
The vehicle model and year alone are not enough; a different part number means a different ECU version. Other MJD ECUs for the Ducato: 55271527 / MJD 9DF, 52000042 / MJD 8F3.BN, 55245014 / MJD 8F3.B1, 55246594 / MJD 8F3.B6.
Important: the MJD 9DF.A1 ECU comes in versions for the Ducato 2.3 Multijet 130 hp, 150 hp and 180 hp. Please state your vehicle power when ordering.
