I have a 2002 M5. I have had a few problems in the last few months with it. It all started when it just wouldnt start about a month ago. There was a clicking noise. I replaceed the altenator and the battery and it worked fine until recently. I was told that it still had a draw coming from somewhere which I have been unable to locate. Last week, it didnt just fire like it normally does. It took a few extra urns for it to start. That problem then sort of went away and today I went out and it wouldnt start. It basically turns over but doesnt catch. After a few hours i checked it again and the battery was dead. I tried to jumo it and it almost atarted but wont. No clicking, just wont start. It does turn over though. Please help.
