Most likely due to the alternator. If it is not charging enough to the battery, this might happen. Alternatevly, if you did install any ICE in the car, there could be a current leak in the amp, speakers and all other components. You might want to bring it to the ICE man to check.

I have a 3 month old 525i with about 3500 miles on it.? About a month ago, it started to develop a problem where the battery drained overnight.? A few weeks ago, I brought it in for service.? They tested the car out, could find nothing obvious wrong with it and gave me a new battery on the theory that the battery may have been defective and developed a memory problem where it did not fully charge.
Now, three weeks later, the same problem recurs.? I called my service center and he thinks the problem may be with the computer waking up overnight.
Has anyone else had a similar problem?? If so, what was the resolution?

So the answer is: Bluetooth. I keep a SE T610 celphone in my car turned on at all times. The dealer says that this is keeping the car from going to sleep and eventually draining the battery, even though the key is off.
This, of course, is not documented anywhere in the manuals, etc.
So be warned...if you use bluetooth, make sure to turn the phone off or take it with you.

If that is indeed true, you might want to post this information as a new topic so other BT users can chime in with their experiences.

So this is an update on this problem of the car spontaneously seeing a battery drain when left overnight. (2005 525i 9/04 build date).
Originally, the dealer thought this was due to my keeping the BT phone on and in the car overnight. Indeed, when I stopped doing this, the incidence of the drain dropped from every night to once every week or two.
The dealer has now had the car for two weeks and the SM called me to say that it finally died again last night. They did see the car wake up, but are not quite sure why.
Meanwhile, I am talking to the Sales Manager about getting the car replaced or getting out of the deal entirely and giving up on the E60. Not sure what I am going to do. One part of me just wants to find a nice 2003 E39 and go that route.
