2004 BMW 530i ALARM GOES ON AND SOMETIMES CAR DOESNT START

About once a week in the morning I noticed that my 2004 BMW 530i wouldnt start. All the instrument clusters are lite up however the engine doesn't even crank. Prior to this when I had my old battery the car did the same thing but now with a new battery its still doing the same thing. Any ideas?

And just this morning before this posting my alarm went off unexpectedly.

The car starts when I give it a boost however I do not want to keep boosting it as I might blow my alternator (if its not gone already).

Help !!!

    Thanks a lot for this response. I know I was thinking the same thing. In a way its good that I did change my old battery because it has been about 5 years since. How much would an alternator cost?

Your alternator is draining your battery to the point that you will still have your lites but will not have enough to start your car. I would take the alternator off and take it to your nearest automotive center to get it tested. They usually will test it for free. Hope this helps you get back running.

I had a similar problem, 2003 530i, but only while the alarm was active. The culprit was a bad hood switch that was making intermitent connection.
