Hi guys , I just bought a 2003 Z4 and when I try to clean up my new toy then I when to the battery and found a big plug with wires that’s have been cut and connect to each other , but the module or whatever component the plug have to plug in is not there . So with my thoughts is there any module or component is next to the battery ? It’s maybe broken so the bmw tech discard it and try to bypass it ?
