I have a problem with my electronics in that my power steering and door locks to include trunk locking mechanism and all interior lighting don't work. The moonroof and windshield wipers are also inop. The drivers window still works to include mirrors. Maybe a general module?
What could be the cause of my power accessories losing power? on 1999 BMW 740i

Sounds like it could be a common control module except for the power steering thing. But im not to familiar with German control systems and which systems they would group on the same ECM Did you check ALL your fuses?
