For a few months now there has been a whining sound., directly coupled to engine RPM, and independent of clutch gear or speed. At first I thought it was the PS pump, as the fluid was slightly low, but topping it off did not help. It is coming from that general area but it's really hard to pinpoint. I'm guessing it may be PS pump bearing, alternator bearing, water pump bearing or, (perish the thought) timing belt tensioner. Can anyone offer any advise? It like to get it squared away before pending ECU tune.

Re: Whing sound (Chazwr)

Start your engine. Place a wood stick on the body of suspected problem part. Hold tight with your hand on the other end of the stick lean on it with your ear. Listen for noise and feel vibration. Make sure you are not touching anything moving. (Does this make any sense? <IMG NAME="icon" SRC="http://www.vwvortex.com/zeroforum_graphics/screwy.gif" BORDER="0"> )<br>You should be able to rule out any bearings either on PS or alternator. <br>My guess: alternator.<br>Good luck.
