Telematics Control Unit (TCU) Pull fuse 74 in the back and see if the car goes to sleep after 16 minutes. It was the problem causing my parasitic drain a couple of years ago and keeping my X5 from going into sleep mode but mine is a 2004.

Yep. TCU is frequently the problem. Finally just dumped it on mine as I never used it anyway. Haven't had a parasitic drain problem since.
