I've been having an intermittent issue on my 2001 530i. Sometimes when I start the car the battery light stays on to long, when this happens, reving the idle takes car of it. If the light stay on within 2-3 mins all the lights come on on the dash and the car shuts off, I've found that if the light stays on I can shut the car completely down wait a couple seconds and start it back up and the light goes away, and all is fine till the next time...could be two days could be two months. Sometimes however I'll have a few starts where the starter acts like its lacking sufficient power to crank the engine, the engine will start and run fine till either the car won't start or the the battery light stays on. But this time when i go to restart it, it won't start. These times when the car won't start I hear a clicking sound coming from behind the dash, with the lights on the dash having a faint flicker with the click sound. At this point all it takes is a jump start, and not much of one hook-up the cables and turn the key and it fires right up. If I let the car run till it shuts off, I have to hook-up and wait a few mins. This happens give of take every 6-8 months One time I left the car running with the battery light on, the other lights started coming on, I hooked-up the jumper cables with car still running, the battery light and all the other lights went off and the car was fine. I've had the charging system checked numerous times and everything is always fine, I've also taken out the alternator out of the car and it tested by itself a few times at different places including the shop that rebuilt it for me 3-4 years ago (great alt shop, I've used them for years for numerous vehicles).
Any advice that you can give me is greatly appreciated. Thanks
