I went in last week with the same problem, they initially denied they'd ever heard of it. Then as I was taking to the service guy behind the desk (who was new), said they'd replaced several of these already. Warranty guy then owned up it was a common problem, and that he's going to get official word from VW.
Today I was told they want the car for 2 days. They are going to bond it first with vw glue, and if that still doesn't hold then they are going to give me new parts. I'm not sure why they want it for 2 days, but I'll give them a chance.
