There is an updated arm. When I switched them out it made the problem better but not fixed. I have an aftermarket replacement windshield and I think that is the major problem. On the Touareg I have that has a dealer order replacement windshield there is not the problem that was there with the aftermarket windshield.
Not handy. If you order a new one from the dealer it is that part. I got mine from vwpartsvortex.com But any dealer source will work. I was really surprised how low tha cost was. I think around $40.00.
