Excessive Battery Discharge
I have a unique issue in my 08 535XI., at least I think it is unique. I often get the Excessive Battery Discharge error come up On my iDrive. The time resets as does the trip computer however I never have an issue with starting the car and it always starts up fine. My understanding is that parasitic battery drain will drain the battery completely until the battery is dead. Are there any common items to look at given the symptoms I described? Or could my car have any of the typical parasitic battery drain issues?

I will check the draw after the battery has gone to sleep.

Any recommendations for a new battery? I will just order the Odyssey from FCP Euro if there really is not one that is any better than the others

Do you have any other gremlins in the tailgate area?
I wonder if some intermittent battery drain is due to intermittent shorts in the tailgate wiring.
