Feedback requested-X3 TCU, Battery matter

[shupadupa]

I have a 2005 X3 as listed in my sig with about 66K on the odo. Obviously i am out of warranty. It has factory NAV, SIRIUS, BT, etc and the other day the SOS light on the headliner started flashing. As a result it eliminated the sound of the radio and BT applications on a Thursday. I believe it was trying to sync a phone call (that is my hunch) even though my wife never pressed the button. I did some searching and i couldn't "reset" i through the volume/CD Eject button combination reset, so i scheduled an appointment with BMW for 7AM Monday.

Since the radio wouldn't work we decided to drive my Evo over the weekend and on Sunday, due to that TINY light flashing, the battery was dead. I jumped it and let it run on Sunday enough to keep a chrage and drove it to BMW on Monday. Turns out the the car had a dead battery and a bad TCU. They did a service authorization to cover the TCU under warranty even though the warranty had expired which is great (as i have to trust they actually did give me the $2,000 part) but i paid for a new battery and labor.

I just wanted to ask if anyone else has had this problem that was that drastic and i couldn't find anyone that had the SOS light flash that the problem turned out to be that catastrophic?
