If this is for a Scirocco I doubt if your will be able to find a new VW part at a dealership.
I would look for a replacement at a junk yard.
You can try the link set forth below:
Used VW Parts - Used Volkswagon Parts - VW Bug Parts - VW Jetta Parts
If you find a replacement part the change out is pretty straight forward. Go to an auto parts store and purchase a Haynes or Chilton repair manual for your year Scirocco. Should have directions and pictures to aid you. Cost of the manual should be around $10 -$12.
