  one problem is: when diagnosis, your laptop display time must be adjusted to the time before November of 2008, for example, it can be 20/10/2008.   another problem is :when the VAG 812.4 USB connected to the laptop, do not promptly begin to diagnose, wait for about 2 seconds until “Ross-Tech HEX or KEY USB Interface” appear under the Device Manager more information from below website dash-can-517-advanced-diagnostic-tool-397.html
