SOS Call System malfunction after combox retrofit
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 ...
