Disabling that one bit killed it? Did you get any error codes after operation?So, I borrowed a VCDS and in the telematics unit long coding, I changed bit 0 to 0. (1 was for Carnet installed and 0 for Carnet not installed). For those still looking for a solution, this seems to work.
After having done this, I called Carnet to see if they could still see my car (apparently against their policy) and decided to have them disable Carnet from their end. Turns out, this was an option from the beginning. Although, I'm not sure if they can remotely turn it back on if they can remotely turn it off.
Also, how did the conversation go like regarding the call to Carnet; i mean were they forthcoming with helping you or did you have to struggle to get it disabled?
