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 1998 Schwartz II sport 318ti - M50TUB25/5 | | | 05-10-2007, 02:51 AM | #3 | Senior Member Join Date: Feb 2007 Location: Beaufort, SC Posts: 298 | 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.

Jeeez, lots of these going out lately... __________________ '99 Dinan M3 | | | 05-11-2007, 03:08 PM | #7 | TRETEN IRGENDEINES ESELS Join Date: Aug 2004 Location: Rhode Island Posts: 3,687 | 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 clear outs all around,stealth turning signals,blue led interior lights, 35% tinted windows,K&N air filter, 12" Kenwood Sub, MTX Thunder Amp,Alpine cd changer, Leatherz Armrest,ACS Pedals/Handbrake/FloorMats & Vitesse Tuning Carbon Fiber B-Pillars/CF Spark Plug Cover, New 16" MSW Typer 14 Rims on Goodyear Triple Treds www.myspace.com/avusblueti | | | 05-11-2007, 09:11 PM | #8 | Member Join Date: Mar 2007 Location: Texas Posts: 51 | dusten u happen to know how to fix the secondary pump? | | | 05-11-2007, 09:58 PM | #9 | doesn't care about you.

Replace the valve while you are in there. Total for parts should be about $400 and it takes 30 minutes to do. Parts are available from Pelican and Bavauto. Good luck. __________________ '99 Dinan M3 | | | 05-12-2007, 01:44 AM | #10 | Member Join Date: Mar 2007 Location: Texas Posts: 51 | *sigh* another $400 to the bill... | | | | Currently Active Users Viewing This Thread: 1 (0 members and 1 guests) | | Posting Rules | You may not post new threads You may not post replies You may not post attachments You may not edit your posts HTML code is Off | | | |
