Sounds like your turbo is saying bye bye. And no, that noise is not normal.

Yea I figured it wasn't normal. I was going to go BT anyways so now I just found my excuse. I would like to be sure though.

Anyone else?

Out of curiosity, does the noise change with revs,boost?

It might be worth dropping the aircon pump belt off to be sure it's not that

Sounds like a bad belt

11-15-2010, 11:27 AM
Maybe Alternator whine? From an Alternator sayin bye bye

My turbo whines and has the dentist drill sound, but never when I'm parked and revving it. That sounds different, like one of the front drive belt accessories.

My turbo still makes full boost though....

Yes the noise does fluctuate according to the revs. As for alternator, I havent had any issues with the battery draining lights/accesories dimming at night or anything so I dont think that has anything to do with it. The turbo still makes boost although I'm not driving the car due to the cam gasket leaking. Aircon pump belt? Please elaborate. Thanks guys

Anybody else??

11-21-2010, 10:36 AM
i would say turbo too... alternators would whine more and dentist drill.. hope you got some money saved and ready! :/ sorry

edit: check to see if your belt it loose though.. have you gone in to really listen where its coming from??

Have you opened the hood and looked/listend a bit closer?

11-21-2010, 01:42 PM
Yes I have, it sounds like its coming from the front of the engine. But I can't be sure. It does get louder as the rpm's climb though.

take the small blet off at the blottom of the engine on the left as you look in. Thats the aircon one. See if that makes a difference
