06 525xi awd/battery drain

[spyderg0d]

A few weeks ago suddenly the awd/traction/abs/red brake light all came on with emergency something screen on the dash.
My guess is the transfer case actuator is bad.
But would that cause the traction control to stop working along with the abs? Seems an odd safety measure for the culprit.

Also. Directly after this the car started to drain the battery when parked. Alternator checks out to put the voltage out and charges the battery when driving. The battery is new agm, I even had advanced replace the battery that was still under warrenty just in case. Currently having to unplug the negative terminal to keep the battery from draining. The micro power module seems to be fine, has been located in the trunk the entire time I've owned the car.

Anyone have any troubleshooting tips besides pulling every fuse 1 at a time. (I already did that).

Replaced the micro power module. Didn't stop the battery drain?

Can a bad awd actuator motor drain the battery constantly?

Ended up being a wet/shorted tranfer case module under the front passenger seat! Once it dried, power problems went away. The module ended up being bad after.
