Very easy to do. Two screws hold in the alternator voltage regulator and
brushes module. I just recently replaced mine. I had to use a channel lock
pliers to remove and replace the bottom screw. I paid $37 for the part from
a discount dealer. The VW dealer wanted double that. No need to remove the
alternator. Just angle in the new brushes, tighten and you are good to go.
If you need a photo of the regulator module pmail me and I'll take a digital
photo.
