Scano.ie's response also cured a similar fault I was having with my 2014 tiguan. I changed my MFSW to remove Push to talk (PTT) and a Telematics code started showing. Making the 3-button key NOT active fixed the 75-telematics fault I was having.

Code:
2103041 - Control Module 
          B1788 F0 [009] - Start Prohibition Deactivated
