Power cuts out upon starting! And other problems
My dadís 2000 740iL just started manifesting some strange electrical problems: once in a while, the car will completely die when the key is moved into the starting position. Completely die, as in no power to anything. 5-10 seconds later, the power returns and the car is able to be started, but the seat memory module forgets all its settings.
After a few botched startups like that, the front right speaker has also begun emitting a constant, loud buzzing noise, even when the radio is off. Changing the audio system balance does nothing to relieve the noise.
I was thinking this could be the ignition switch, but I am told that opening the passenger visor mirror has no effect. Does anyone have any ideas?
