I cant seem to get my obd cable to talk with my beetle. The cable is new, so it cant be that, the laptop doesnt have any software that is specifically for the cable. the software i do have tells me there is an error with the interface. and the only thing that could be considered a problem with the car that i can think of would be the aftermarket radio that is installed. I am going to check out the radio issue tomorrow, but any insight into how this process works would really be helpful. Does the software matter? is there a generic program that can be used? I am just trying to clear a CEL light and if at all possible the airbag light( unless there really is a problem with the airbag) Thanks for looking and assisting!
