Doba_s, you've given me the courage to install mine myself. Thanks for a great DIY.
I was wondering, when you take all the wired out of the black plug that went in the original CPC, what did you do with the empty plug. I've had a look at the new CPC and there is two connectors, one is obviously for the white one with the old wires in, the other looks like it would accept the old plug.
Is this something to do with the fact that the new CPC is that same as the one for an X5 with heated steering wheel?
Do you know if everything is back to front with a RHD car - as in the blue connector at the beginning of your post, is that on the opposite side of the car?
Thanks again for a top class DIY post.
