Same thing happened to me. I had the rim refinished back to new for $125.
So I went to the body shop I usually go to for work and they said that they do not repair rims. I then called the VW service department and they said that they also do not repair rims but they do have a guy come in every other Tuesday to do all the rim work. So I called that guy and he quoted me $45 to fix my rim. Thank goodness.
