Hey guys, hope you can help. I have a 2010 touareg v6, 20k mileage. While I was driving I heard a loud high pitched screatching noise started coming from what I believe is the right rear tire. It sounds like I am dragging some metal or something. It does not make the noise while in reverse. But it continues while in neutral moving forward. I plan on taking it to the shop shortly. It usually gets louder when I turn left. Does anybody have any idea what it might be, or has anyone else had this problem?
