Im new to this so apologies for my ignorance right off the hop here. I purchased a RossTech VCDS off a buy sell site, I appears to be genuine, but what do I know. Says Rosstech on the plug and even the velcro strap says RossTech. Downloaded the latest software (on a Microsoft Surface Pro, and then because I was having issues on my PC), its all plugged in, LED on the cord is lit, key is on, getting a "no response from controller" when attempting to do anything. It also seems like lots is grey out and un-selectable. For example when I go to the "Auto Scan" page, It won't automatically find my make or model, when I choose it (BP - 2011 Touareg TDI) it a scan, takes all of 1 second but theres no data, guys on youtube have a gateway installation list that they say might be the issue but that button is greyed out. Any tips or links would be appreciated!
