I seem to be having a few difficulties getting vag-com to work . I'm using an non opto cable, using v 409 of the software.
When I test the cable it come up saying " test ok, non opto cable, genuine rosstech interface" everything looks ok here
Then when I connect the cable to the car, I get a message saying "interface not found"
The annoying thing is, that the first ime I tried it, everything worked beautifully! It was only after about 10mins of messing around with the software it all went wrong. Last thing I accessed was the "sound system" tab, after that it crashed and has never recovered.
I have tried it on another laptop, still no joy. Not got access to another car or cable, so not sure where to go next?
Any ideas out there??
