so my car started making the wierdest noise ever. Its kinda like a mix between a whine and a screech. i would like to say its comin from left of the engine(drivers side area) and no farther bak than the front left wheel. i believe its my belts but i dont know how to fix it, i was thinkin it was somethin wrong with the bearings(spelling?) or somethin but idk so i didnt wanna try anything before consulting you guys, so anyone have any idea on what it might be, and if so a solution? |  |  | | 05-10-2007, 01:25 AM | #2 | | Senior Member Join Date: May 2006 Location: 43609 Posts: 3,425 |
Is the sound audible depending on the revs of the engine, or by how fast the car is traveling? If you think its a belt, then start the engine, pop the hood and listen to where the sound is coming from. The possibilities are: tensioner pulley, power steering pump assembly, alternator, or maybe the a/c (a bad a/c compressor will rattle, rather than whine or screech). If its based on how fast youre traveling, you may have a bad wheel bearing. __________________ 1995 Hellrot Clubsport 318ti -Gone 1996 Schwartz II Sport 357ti - 5.7L V8 LS1/6 1997 Moregrun Metallic 318ti - Gone

listen to see if its not coming from the the section leading off of the Airbox mine was making a whining noise... turns out to be the MAF | | | | | 05-10-2007, 03:33 AM | #4 | | Senior Member Join Date: Apr 2005 Location: N. Texas Posts: 187 |
I have the same problem, haven't figured it out yet either. I am under the impression that one of the tensioners is going bad, but I have more issues than the belt whine so I have to fix it | | | | | 05-10-2007, 11:57 PM | #5 | | Member Join Date: Mar 2007 Location: Texas Posts: 51 |
the noise only happens after starting the car fresh from not runnin in a while. like once i drive for about 5-10mins it goes away. so i have no clue what it could really be, only happens when i idle like at a stop light or parked in my driveway. | | | | | 05-11-2007, 04:50 AM | #6 | | doesn't care about you.

It's probably your secondary air pump.
Jeeez, lots of these going out lately... __________________

I think I posted a comment in the wrong thread on this yesterday. I have a simialr problem annd came tro find out it's the ball bearings in the waterpump that make a whining noise onces started and goes away after a few minutes. When it was colder out it was more noticeable,now that it's warmed up i still hear it but not as bad. I'd also look into that. __________________ 98 Avus Blue 318 ti Active
