My B6 A4 has had a few problems in its life time. Right now the two major ones are the sunroof and radio volume ****. First the sunroof, many others have had problems with it I see, mine as well as not wanting to close sometimes, will close randomly when I have it tilted up in the back. I was wondering if anyone else had this problem and knew how to fix it. The second problem is the volume ****, whenever I try to change the volume (up or down), it is very unresponsive sometimes jumping up or down 6 or 7 levels as at time. I figured there's not much I can do about this but does anyone have any knowledge about this problem?
