More to the point: What could be wrong if the OBD isn't communicating?
I took it back to original garage, and he couldn't talk to the computer anymore either. I can ony assume that it's not the computer itself that's not working because I would expect to see a lot more problems if that were the case.
Has anyone ever seen a problem like this before? I honestly don't know where to start looking.
Thanks for any help at all.
