I need to put a new T-belt on the S4 and am wondering if this is like the older 5 cylinders where you loosen up and replace the water pump to do the t-belt. Motor is non interference, yes? I know, I am one of these lazy Audi folks who buys bently manuals only in desperation, a point I have not yet reached. So, becuase i have no manual, i turn to all of you. Thanx, SHayne.
