Do you mean some fuse removal, or actual removal (or connector disconnect) of an actual TCU module itself? I just want this parasitic drain nightmare to end and since you were able to fix it I'm hoping your cure will work for me as well. Can you tell me exactly what was done?
Thanks!

If you look in the rear left compartment where the nav equipment is (if you have it) you will see a long metal box attached to the rack, if you have blue tooth. If I can figure out how to upload photos I'll post some. In any event if you pull it out and disconnect all wires it will be impossible for it to drain the battery if that is the cause. From what I've been able to find the TCU and the fan control are common sources of parasitic drain.
