from reading I know the program and hardware I need to code a retrofit CCC to CID X5 E70 but there is nothing I can find about the steps after the CIC install with bimmerretrofits special cable. I know you still have to do some light coding. Is there a link anyone could send me to read up on this? I would like to do the basic coding myself. I would not do the software updates or any fancy stuff but I think that could I do myself.
