Hey! Having read all the existing threads talking about how rare this part is I thought one of my best options was posting here in case anyone has come across the module or could be of help getting access to one. I understand that there are retrospectively exchangeable parts (but since my z4 is a 2003 I'm not sure if all older models are compatible (given that they are not bilaterally exchangeable). If anyone knows of any breakers or potential suppliers, that would be extremely helpful. Anything at all really would be much appreciated. Thanks a lot!
