profile. That should be step #1. Is it an NA or TT? What year? If it's an NA it could be a tire, bushing or alignment issue. If it's a TT it could be a Hicas issue in addition to the previously listed possibilities. Early TT with hydraulic Hicas can exhibit this problem if there is a fluid feed issue to the rear steering rack. I had this problem when I had a crushed Hicas fluid hardline near the rear of the vehicle.
