Hey guys, I've been having this problem ever since I had the water pump, timing belt, and accessory belts changed but I just assumed it would go away after a while. I've been driving on these fresh parts for ~3k miles but the whining/whirring sound at idle is still there. If I rev my engine, it kind of sounds like a supercharger. The whining noise at idle comes on after the engine has warmed up. The car runs fine, doesn't hesitate and accelerates great. The whining noise is quite loud. The exhaust I have is pretty loud and I could hear the whining/whirring noise if I stand behind my car. The noises are coming from the front of the engine and I believe it has to do with one of the accessory belts or a pulley. What could be the problem?

I would be worried that the timing belt was misaligned/too tight/had a bad idler etc and
I'd take it all apart again.
But first, with the engine cold, take all the other belts off and see if it's quiet. That rules them out.
tnow, sometimes I just mess with people. It's more entertaining that way. george graves

I would think its the voltage regulator in your alternator. Pop your accessory belt off and see if the noise goes awayThe best one-stop shopping for German car parts and lifestyle: http://www.gutenparts.com/

I just put my car back together, and I have a similar sound - like you said, like a little supercharger! I wish. It goes up with revs. I was thinking alternator, but I guess it could be the timing belt? I did it by the book, and just let the spring set the tension. Didn't seem like it was too tight, but I don't know. Makes no difference hot/cold for my issue though. I noticed it immediately on the first drive.
