Squueking noise from engine?
Hi Ive got a 2000 a4 stock vette. It has a squeeking noise I thought came from thwe belts. I had the dealer check the noise and he suggersted I change the belts which I did and also the belt tensioner which I did. Sure enough a couple Of days later sqeeky noise is back?
Was there a bullitin out on these cars for squeeky belts..Something about a bracket?/
Any suggestions would surrely help.
Thanks, MIKE

I don't know anything about a bulletin about squeaking, but I have had the problem on my '02 and on my wife's '98. In both cases I used a combination of WD-40 and Belt Dressing, both of which I bought at either a Kragen or Auto Zone car parts store.

There was a TSB for 98-99 models for the idler pulley.
Bulletin No.: 99-06-01-007
Date: May, 1999
TECHNICAL
Subject:
Accessory Drive Squeak
(Replace Idler Pulley)
Cause
The idler pulley dust shield may distort during assembly due to torquing of the mounting bolt. This distortion may cause the Idler pulley dust shield to contact the bearing race and the pulley resulting in the squeak noise.
A new idler pulley assembly is available with a thicker dust shield to prevent the distortion of the dust shield. The previous dust shield thickness is 0.61 mm. The new dust shield thickness is 1.37 mm.
Important :
^ Do not over-torque the mounting bolt or the condition may reoccur.
^ Do not use pneumatic or electric tools for installation of the idler pulley assembly.
Tighten
Torque the idler pulley bolt to 50 N-m (37 lb ft).

Plus you do realize there are 2 tensioners. One for Accessory & one for AC. I would leave the AC belt off completely to see if the noise stays or goes away.
