SOS Call System Malfunction
 
My problem finally solved. I took my 525i to an independent repair shop and in 1 hour they determined thru a diagnostic check that the Telematics Control Unit (TCU) was bad. After it was replaced everything works fine, including blue tooth. The TCU is an amplifier looking box located in the left rear of the trunk. It was easy to remove & replace.

Out of interest for future posters - would you mind sharing what the replacement part cost - parts + labor?

thx

I had the same error and deleted the SOS option from my car via programming.

Is anyone has a good procedure for this as what it has done at BMW coding website?
Also may be someone has NCS Expert and INPA to do and has experience with it

I found a guy on BMW coding that will do remotely coding. If you need contact info let me know.

I found a local BMW mechanic in Dallas, not a dealer. The TCU was $276.50, reprogramming was $150, plus $75 for diag.
