Somewhere around March 2015 VW changed the encryption on the ECU's and Superchips Bluefin won't work on those ECUs.
I spoke to Superchips about it when I had my R first of all. Mine was registered early May 2015 so would have been built around the time the ECU changes came into being. They said my car would be 50/50 whether it was locked out or not so I went for a JB1 instead.
