Squeaking/Pulley problems on your w203?
How many of you have had pulley problems with your w203? This is my 4th pulley replacement in just 6 months..1 idler pulley and 3 alternator pulleys (belts were also replaced).
It is a squeaking noise when your car is in idle but disappears after the engine warms up.
Is this common for the m271 engine or is it just my car?

wow, that's crazy.
I have over 70k miles on my C230 and the pulleys have held up (knock on wood) fine. I've beaten the crap out of the car too.
I haven't heard of other members with problems with their pulleys either.
good luck with everything.

hey did u have any wierd sounds come when u turn ur car on, like for few seconds, it would sound like a loud ticking noise but dosent happen on cold starts. usually after driving then parking for an hour or so.
also when the is in drive at lights it makes a loud noise sounds like a fan but seems to be too loud since heard inside the car
let me know if this is something you have been having

Thread hijack... Odessit, there's a guy on here with a high mileage C230 that has had its alternator sprag bearing go out a few times. He described the symptom as a rattling noise and said if it is not caught early, it can ruin your A/C compressor. What year and mileage is your car? This is just a guess based on what I've read on here before. My car has never done this.

I have been noticing some kind of squeaking noise as well, but it mostly happens from a cold start and then goes away. I can't make out exactly where its coming from though...
Did your SA happen to mention which model years are affected and/or covered for the pulley service campaign? My car is nearing 96K miles now and I haven't had to replace any pulleys yet.

EDIT: a long heavy duty pry bar should help when moving these things.

The worst pulley noise I ever had was when I was using a Goodyear Gatorback belt.

My SA did not talk about any other years being affected, but I didn't ask.
My 2006 now has 28K miles now and I clay-barred it yesterday.

when my engine is cold i get a pulley squeak. after driving it a about 30 mins or so it quiets down, but can still hear it. my mechanic said that the idler pulley was a common problem with my car. (engine 272)
i feel his diagnosis is accurate, however, i no longer trust my mechanic. so i have been working on my own car. but, im a strickler for accuracy (OCD) lol. everything to perfection, especially torquing every bolt. lol.
does anyone know the WIS diagrams to complete this job?
better yet, where can i get a good copy of the WIS system?
