Are you using a HEX+CAN interface? It is not VCDS that is at issue. The interface cable is at issue. HEX+CAN is good thru the 2015 model year on most cars... but in 2016 life changed in the VAG lane. HEX+CAN could not handle the changes and all new interface products were introduced.. We have an upgrade program. Let us know if we can help further.
Start a dispute with eBay stating that the cable is not genuine and is a rip-off copy.Thanks for the reply Bruce, I have gotten to the bottom of the problem now. what I thought was a genuine Ross-Tech product has turned out to be a cheap ebay knock off. So at the moment I am not a happy bunny as I paid handsomely for it. the interface must have inferior internals.
People think they are getting a bargain when in-fact they are buying junk that doesn't work and can possibly screw your expensive car.
