How about the telematic unit? Aka the TCU or bluetooth module. It's known for causing a draw.

My 02 does not have the TCU option. I am scanning it with ISTA now to see if any errors relating to this pop up.

I Had a GM error for potentiometer and cleared all the errors and so far the light is stayin off for now.

WOW! :wow: I didn't realize so much was on there! Troubleshooting is definitely going to take some time. Even using my Foxwell, I doubt it will be easy to find the no sleep problem. I need to find a BMW tech that can help me.

Thanks for posting the picture!

Shifter light is still off and battery voltage sitting steady at 12.5v.

Working through this with the help of a good friend to get my 10.25 android installed. It is plug and play for every other non molested E53s but not mine. We got the original radio adapter i purchased off ebay re-wired in and this allowed the head unit to be plugged in and tested/powered up from the trunk. Using the great trunk radio connector pinout information in the forum I noticed not everything like the 6CDC white connector/wires needed to be rewired. Moving over to the amp connections and everything is done besides the large black connector that was cut pretty close to the connector. I will be sourcing one with longer wires coming out of it. I will probably start a new thread for this in the near future.
