Hi guys, I am new to bimmerfest. I know it's an old thread, but THANK YOU ALL for the detail instructions. I replaced the FSU today and hopefully it would fix my battery drain issue.
However, my "Max Cold" button still doesn't work. I think it's another issue with my CC control panel. When the CC is off, and I hit Max Cold, CC is turned on, but not to Max. When the CC is on, and I hit Max Cold, CC remains unchanged (not going to Max either). My car is an 02 530i. Any tip would be appreciated. ^.^
