I'd imagine it would fit, this will be my back up plan if my plan A of fitting mk6 Golf heater controls to my 2009 Jetta in the hope that being a late model it has the same motor for controlling air director dial as the mk6, or that 2010 Jettas with mk6 heater controls in a mk5 dash use the same front as a mk6 but with the rear of a mk5 set so I can still change airflow direction, failing that I'll see if I can separate the back part of my existing heater controls and mate them to the front of the mk6/2010 Jetta ones which seems possible because the face is just screwed onto the rear.
If none of that works I'll be sourcing the Beetle ones like in your pic.
