This started happening in the summer. It had gotten real dusty in there a few times. Maybe try a can compressed air around the edges of the knob and see if the scraping goes away. I got the same dual control in Canada ver Off Road.
Well, I had my 6 month service Today. I asked them to take a look. They're replacing the entire cluster tomorrow. Appears they know about it and immediately decided to change it out. Free of charge to me of course. :rockon:
