Coding for BT via TCU
 

Hi Guys, I have but a 2005 TCU (ECE/GSM model) in my 2001 X5.
I have the S640A Telephone preparation and no other phone related codes.
The TCU came from a working 2005 X5.
What code should I have to apply to my 2001 X5 as the Bluetooth function is not working currently?
I can make emergency SOS calls from the TCU and when I hold down the Voice button on the steering wheel I get Voice Commands in German.

in 2001 i think you need pairing button in the central console and in 2005 - you don't... this info needs to be verified though...

even for TCU? ULF for sure, but TCU I though was in pairing mode for 2m or something like that from 'start'.

I've given up on the TCU and bought a ULF. My pairing button for now is NAV coder :)
