Engine Mechanical problem
2002 Audi Quattro 6 cyl All Wheel Drive Automatic 88000 miles
I have an audi 3.0 a4 quattro  I changed the waterpump then I noticed that one of the cam pully was loose. I removed it then put new screws in it, The timing got messed up. Have the tool to hold the cam shaft but unable to set the timing. Have you got any instructions, diagram or tips on resetting the timing.
