a4 2.0 tdi steering wheel/serpentine belt
I've got a 2005 a4 2.0 tdi. When I fully lock the steering wheel right, left or approaching fully locked I get strange noises coming from the alternator area.
So the other day I got a friend to lock the steering wheel whilst I looked at the serpentine belt. As he turned the wheel I could see the belt physically jump at the alternator pulley.
Can anyone suggest if its the tensioner thats gone? or can I raise the alternator so that the belt is tighter as I believe the tensioner is a self adjusting tensioner? Or is it some other pulley?
the tensioner looks like its working moving from side to side I estimate 5- 10mm.
Thanks in advance
