What VCDS cable do you have? Lite should have never for the mk5 - it communicates over CAN, lite only supports k-line.
If it does not work on new laptop which one do you have and what exact version of windows and which VCDS lite?
I can put my full HEX+CAN cable into dumb mode and it will work on my Win10x64 machine with current build of VCDS lite....
