@Peskyjones I took the old badge off, mines an 05, just pull slowly all around and the whole badge will come off. Leaving you with the black plastic base. Clean that up, get all the stickyness off it, fill in the small hole at the top of the mechanism then I put a MK5 boot badge on mine but I am lead to believe that the MK6 one fits a lot better.
I done all this while on the car, I just made sure the complete rear end was masked up and I done all the spraying and filling in my garage, so out of the wind
