Citroen C4 Picasso II Swap ECU unit immo data

[McDowell]

Helo mates,

Do you know the way to swap these units? I do not know where is immo data stored and how to read?

Ok sorry my fault, thanks for answering.

Problem is I am getting the following DTC

U1218
P1AA2 INTERNAL ERROR
U1205
U1318

I swapped unit and still getting them.... Probably car is the problem?

Thanks
