I retrofitted TCU + MULF modules to a Combox Telematics in my 2011 BMW 335i. Connected everything correctly. Added appropriate options to the Vehicle Order and re-coded kombi, frm and all other related modules with expert mode. All is working as expected; however, I am getting this "SOS Call System malfunction" error. Does anyone know how to get rid of it? Thank you in advance for your replies ...

Do you want your SOS to work?
If you don't you can code the Kombi Module to
not display the error.

note the last entry is the actual solution.

Or you might look see what state those parameters are in.

If I understand correctly, this should take care of it:

The values I changed were in the KOMBI (thanks for the links!). Setting the following two values as below successfully turned off the SOS error notification.

TCM_ALIVE_MONITOR -> nicht_activ
TCM_ID_MONITOR -> nicht_activ

I was able to resolve it. Thank you for your suggestion, CTUNA.

However, in my case, since I have replaced TCU with Combox, I needed to disable following two parameters in Kombi:

COMBOX_ALIVE_MONITOR -> nicht_activ
COMBOX_ID_MONITOR -> nicht_activ

Took a wild guess and figured it out on my own
