VW came back and said the part is discontinued and not available.  Guess I am back to the rubber gasket idea.  I wonder if plumbers putty would work better?

Great suggestion, thanks.  I just sent a message to the local VW dealer to see if they can get them.  If they cannot then I think your idea is a good approach while I wait to see if Van Cafe gets them in stock.  I tried using silicone but that was useless.

those washers are fiber and break easily when you take them out. I made one with a piece of rubber from the bicycle inner tube.
if you don't want to wait, cut a square piece of rubber, make a hole to fit, put it on and round it off with the tip of an X-acto knife.

I just replaced the trim around the driver and passenger windows, including the vent windows.  When I took the vent window glass out on one side two of the pressure washers crumbled.  The only supplier I have found is Van Cafe, and they are out of stock.  Does anyone know of another source or an alternative to using the pressure washers?
