I'm not able to recode my navi unit with vag-com. When I go into the vag-com open controller, the light on my cable keeps blinking red, and it says "protocol: kwp2089" in the top left hand corner and appears to be trying to connect, but never does. When I enter in the new code and click "do it," it returns to the previous screen but doesn't change the software coding. Has anyone else had this problem? Can anyone help me out with this? Thanks.
