Hey Guys,

Just thought that I would update. After countless hours of work and diagnostics we still were not able to find an issue. However, the car has been starting without issue for 4 days now even in cold weather We suspect that after unplugging and plugging connections during troubleshooting we may a fixed it, I am not too confident yet, will give it some time and see how it goes.

I have a new issue which could be related to my existing. It appears that my X5 does not go into sleep mode (after 16min), everything appears to stay on and eventually drains battery. We noticed that after locking the car that the alarm would trigger about 15min later. Initial thoughts were that it could be hood sensor switch (common problem) but I know low voltage can cause this also.
I charged battery overnight and verified proper voltage then left it off charge for the day and came back and it was flat dead.

So from what I can tell, internal climate control fan stays running all night, as well as gear shift light and other features. I confirmed by leaving window down and periodically checking after sometime and sure enough car still seemed to be awake even overnight.

Have never ran into this before, what would be the possible causes for this?? I realize I have parasitic draw happening but what would cause car stay "awake"

Thanks Fellas!
