Hi guys. I am new on the forum and aware that this might not be an all new thread. My 2010 e90 tcu/mulf got wet at some point & tried to somewhat dry it. I later realised that one of the little pin in the blue connector was broken. The radio/cd plays well but the problem is that the bluetooth/usb/aux doesn't seem to work. Is it possible that broken pin is the cause or the entire tcu/mulf has packed up? Please help!!!!
