HI, any update on this? I have a 2008 550i and am having the same problem. Sometimes it takes 30 minutes of trying for the car to start and it randomly shuts off as well. Its been in the shop for about two months over the past year and they can't figure it out. So far they've replaced the starter, the CAS (key receiver), and a cell or two in the battery. I'm at my whits end. I'd suggest posting a complaint with the NTSB (http://www.ntsb.gov/) as this is obviously a serious safety issue that BMW needs to address. If we get enough of them out there they will be forced to take this seriously.

Hey Bud... Michael here. I had the same issue- drove me crazy. The car is fabulous and yes periodically the start button would not respond. Occassionally the car would shut off while driving and just coast to a stop. Pretty dangerous problem. Stupid for a $71,000 car. OK... United BMW of Gwinnett in Atlanta nailed this problem. Luckily I was able to replicate the issue with the shop foreman right in front of me at the service valet... The repair is a $116 part. Yes, crazy. The labor was a few hundred extra. Now the car is healed and I love it again... I screamed at BMW and told them to update their database to help other 550i owners across the world. Contact me if you need any other info. The part is: Failed "IVM" or Integrated Supply Module. Part# 12-52-7-510-638 for $116.05. I am hopeful this works for you too!! Email me and let me know if this nails your issue... Then you can love your car again. Mine is perfect again and hope your will be too. Michael.
#56 of 83 In response to IVM
Feb 15, 2012 (10:20 am)
Hi Michael or anyone else- Over the last couple of weeks, my car hasn't started on a few occasions (BMW 525 2004). I eventually got it to crank after trying a few times. Well, this morning my car won't crank at all. My car has lights on the dashboard. My husband jumped the battery, but it still didn't crank. I don't want to have my car towed b/c I feel it might be damaged while towing. Any suggestions? I called a couple shops and mentioned the IVM and people said my dash lights would not be on if the issue was the IVM. Any Thoughts? Also, does anyone know how to get to the IVM?
Thanks a bunch! Ashley

I recently had my battery replaced and before that it was sounding real sluggish starting but after the battery was replaced it ran fine for 6 months then it starting sounding like it did when the battery was bad, so i replaced the battery again and it ran fine for 1 month and then it starting sounding sluggish again so now it will not start or anything, I can hear a slight noise when I press the brake in before I turn the key the in gauging of the starter but it will not start. Also just to mention the last time i tried to start my car it sounded like the battery very low but i just purchased it the day before. If any one have any suggestions please help!

It doesn't take much of a load from something not turning off properly to drain a battery overnight. You need a load test to confirm there's no improper load AND you need to verify that the belt to the alternator and the alternator itself are working properly. Throw in a check for your voltage regulator as well. Some of this can be checked fairly easily at home, IF you have the proper tools.

My pleasure Chief glad it worked out. Incredible how many BMW certified service centers are not familiar w/ this easy $350 fix- that causes the owners so much grief. Why can't all the BMW dealerships simply synchronize their knowledge data bases? Anywho, take care... Michael.
