E39, Turn The Key All Goes Black.... - BMW Forum

///Matt · 08-07-2005, 02:04 PM

Today I turned the key to have the car completely black out...no power for anything. Lights, accessories, windows, everything was out. I exited the car, engaged the alarm, disengaged it and then got back in and it started fine. Very weird....it seems like a massive power short. Now i find that the rear woofer is putting out a low frequency constantly. I think that somehow these two issues are related. Has anyone else had a problem like this?

1997 E39 540i

Any help would be appreciated....

I am not so sure how much of a help is this....but I had a similar problem, and the bad boy was the ignition switch ....after the cost of a new battery without testing....it was old anyway !!!

I thought that it might be the ignition switch giving off low voltage....would that even be possible?

If the contacts are dirty/worn, it may be a possibility.
