My coworker got one with this 2007 S8 (he's only in once a week so we haven't tried it yet).... just wondering whether it should work, or whether I'll have to find someone else.
My Ross-Tech VAG-COM is a HEX-USB +CAN. It works with my 2013 and also worked with my 2010 S5 and my 2008 S4. My previous HEX-COM did not work with any of my Audi's. It needs the +CAN part to communicate on the CAN-BUS. I'm not familiar with the S8 platform, but if it's CAN-BUS you'd need a +CAN device.
