When my module went bad, it drained my battery. I couldn't access or pair when I had the car charged up. I pulled the fuse and it started working again, but it started to drain my battery again. Took it to the dealer and they agreed that my TCU was bad. It's not fixed and I just insert the fuse on long trips to use the bluetooth.

There was recall on the TCU's a few years ago but looks like they pulled as I tried giving them the recall #'s found on another board....but they said they couldn't find them. BMWNA could find them either (or said it didn't apply to the x5)

I would pull your fuse. It might be 73 in the back, reinsert and see what happens. Don't be surprised if you battery drains. You'll know its faulty if the red light doesn't disappear when no phones are paired.
