I have the same issue. I have the schematics for the "F1CE0481D" and the "FIAE0481D". The "3" changes in the code. And the actual layout of the harness differs too.

Is there a way for me to access the .rar?

Hey Credoline.

The DUCATO I have is a 2.3 JTD, so, please, the first 2 (EDC16C39 AND MJD 8F3.XX). I have a X250 Elearn manual, but it doesnt support the F1A3481D motor model. Maybe your schemas are different. Fingers crossed, and much obliged.

Cheers.

I found this bit of info. Its all in Spanish, but it relates to the motor model in question. The whole schematic would be great though.

It is so hard to check what fuel injection you have ?

Its a X250 2.3 JTD 130HP/CV motor. Common Rail injection type, like most of these motors. What changes from other models is the ECU, which is why I'm asking for anything you have. I checked the one installed on my Ducato and its a MJD.8F3.
