Mercedes C230 Pulley Noise & Bounce (Tensioner & Idler) + Power Steering Rattle

Idler pulley has worn bearings and causes a hissing sound while running (on very cold starts, the bearings make a loud worn bearing sound) - check out my video on replacement
( • Mercedes Benz C230 (W2... )
Tensioner pulley bounces (video coming soon on replacement) - Bounce was due to seized alternator pulley (video coming soon)
Power steering pump had a very loud rattle at idle. I thought this was timing chain but a mech's steth pin pointed it to the pump. Pump was replaced and the sound is gone (video coming soon)
Putting the car in neutral/D will help recreate the noise and help it stay constantly to diagnose it.
Hi Your noise is caused by the alternator decoupler pulley bearing being seized look up Decoupler pulley to understand and repair.
I have the same problem on my w203 C240 I can here the ruttling sound smthing like a loos metal on the driver's side where the alternator is located n at som time its like its coming from the oil sump but when I Rev the car up to 20 on the Rev counter the sound disappear
Did you manage to get the problem fixed mine is also making this rattle noise
Hello. This is what my power steering pump pulley sounds like... Can you suggest me to a video that will show me how to replace my power steering pump? I've replaced my serpentine belt & all other pulleys are good! 2007 c230 sport 2.6l v6 automatic (m272/w203)
I have a video on how to replace the PS pump as well
More than likely the AC pulley is failing. Usually people will replace power steering pump and still hear it. When the ac pulley fails it breaks apart violently. Mine did it. Broke into several pieces. MB engineers are too smart tho. U dont have to get a new belt (unless its damaged) just have to use a different path to by pass the AC until u fix it. No need to buy another belt luckily my belt didnt get damaged so i just by passed ac until i was able fo fix it
thank you
hey bro did your old power steering pump was actually bad? Mine too a w204 1.6L M271 same ticking noise where the power steering is... just renewed the power steering fluid and still hearing the noise but sometime the noise disappear... dont know exact if the steering pump is going bad or not... i'm confused and a power steering pump is very expensive in my country so i wanted some help...
could you solve it? I wanted to disassemble the pump to see if it can be repaired before changing it
Has the sound increased since the day you started listening to it or did it stay the same? in my case it stops ringing after about 4 minutes
When u say power steering pump rattling at idle, does that mean when you're are in drive? I having problems with rattling around water pump power steering area while in drive and I already replaced water pump and the belt tensioner and it's still there
Try the pulley on the aircon compressor. The clutch inside sometimes gets loose and rattles. Just a suggestion because I had this problem and cured it.
I have the same issue its the power steering
ahmed noori yep! I made a video replacing the entire pump with a used $50 one. Fixed the noise.
Turbine loud just like my c-class you fix it yet?
Please help ! I have a 06 c230 115k miles about a week ago I noticed a pretty loud rattling noise coming from the engine ... when it’s idle or stopped the noise is loud but when moving it is quiet if not any .. when I kame to a stop for a minute my car stalled but then turned back on ... I took it to firestone n they could not tell me what was wrong only said “internal engine noise” and they can’t get inside to see ... today after driving n parking I tried to start my car and the car would not turn over , got a tow home , popped hood , tried to turn car on and when I looked at the serpentine belt it tries to moved but the bottom left pulley (alternator pulley I believe) does not want to give and seems to be stuck.. could this be the noise and why the car does not want to start now? I have not tried to jump the car yet.. please get back to me
Sounds like timing belt
If you suspect the alternator pulley is seized, you should have a undercharged/dead battery that could possibly be causing the no start condition. If that's the case check the battery voltage etc. Does the starter try to crank the engine at all?
I have a same kind of noise but a bit louder like a knocking sound, car is in 118000km with regular service, but the sound started all of a sudden. I took to workshop and they are saying it's a blown engine. I don't even understand how can Mercedes engine blown away so easily. I feel that its something related to pulley or tensioner.
It could be a timing chain rattle, which is not uncommon considering the most common mechanical failure in the m271 is timing chain related. I used a mechanics stethoscope (or any cheap dollar store one) to localize the rattle. It ended up being the power steering pump.
@@SteU4IA thanks a lot for making wonderful videos and replying to me. Now I have some hope. Can you suggest any good mechanics or workshops where I can take my vehicle and who instead of directly coming to a conclusion of engine failure by only hearing knocking sound, Check some other underlying problems. It would a great help. You can directly mail too at kmelbhagathe@gmail.com
The workshop doesn't know what its talking about. When my one C230 had done more than 255,000 kilometers, in a moment of insanity I took it up to 215 kmp, about 130 mph. I think you have some issue with a pulley. Maybe alterator or aircon compressor pulley, or belt tensioner.
What is causing that noise ?
Shot bearings in the power steering pump
Cheers I have the very same rumble on c190
@@SteU4IA cheers I have the very same rumble on a c180
My belt is damaged too ?
Damaged in what way? Try to replace the belt first.
Ste .L i am gonna uploaf tommrow
which pulley was it?
Collin Eliason
it ended up being multiple bad pullies, including a bad power steering pump (it made all the noise). my other videos show all the ones i replaced, including the pump
@@SteU4IA my c180 k sounds exactly like this I pulled the belt off and the power steer pulley seems very slightly wonky will replace ASAP
Hello Ste .L I made this video to show you what my C200 Kompressor is doing actualy, do you think it's the power steering too? I have this weird sound when I start up the car, when I accelerate from idle, or when I steer the steering wheel completely to right or left (that's where I hear the noise most) ty if you can help me : czcams.com/video/S5GW85LAijo/video.html
Hey! Yes it does sound like it's PS. One quick way to diagnose this is go to the dollar store and buy a cheap stethoscope. If the knocking is loudest right at the PS, well your diagnosis is confirmed.
