MAHALOS for your fine work! Did an oil change on my 2010 E350 and the squeak started. Knowledge is power.
Thanks for the info. My Mercedes start making the same sound yesterday and I thought it was a belt. Now I know what’s going. 👍🏾
Stranger.. hello. I got it aswell couple of days ago. What is it???
Did you find what it was?
That’s the centrifuge diaphragm, great diagnosis 👍🏽
Thanks for this! I got the same noise on an 2015 ML350 thought it was the belt but it is totally the air intake valve
Saved my bacon, did an Oil change on one, and it came back doing this, it was driving me insane, so thank you dude
Crispy bacon sauce! Glad it helped out. Eat the customer going to do the work with you guys to fix it? Or did you send him to the dealer
Was it hard to fix?
Thank you! I replaced the belt and pulleys and it didn't fix the noise. Now I know what to fix. You nailed it. 2014 E350 with 60k miles.
What is it same problem ?
E400 80k
WOW
Great stuff. I've been out of the trade for many years now but I still like seeing this type of thing.
Do more like this.
I'll hopefully be out of this trade to one day! Thanks for the feedback.
Thank you so much for making this video
This video was excellent. Had the exact same problem. Going to order the hose and see if it works.
Hi FJ, did you end up changing the part and did it work?
I found that you can also pull the oil dipstick out about 1/2” inch, you get the same result as removing the oil cap. Great stuff. Thank you. In your professional opinion, how long should an experienced mechanic take to complete the entire repair?
Honestly I'm not sure because I didn't do this job. Customer decided to sell the car
Mine is doing this same thing has the same codes any idea on what I need to replace exactly???
@@stevenmartinez8240 hi, i have now same 2 codes here, could you fix it? What needed to replace to fix ? Thanks
Did you ever find out how to fix the problem?
@@stevenmartinez8240 Hi steve. Did you ever find the problem in your car?
Thank u for confirming my problem
Thank you so much. This helped me find the squeak. But now how to fix it. The crankcase vent valve looks difficult to replace on my 2014 c300 it’s behind the passenger cylinder head.
No problem! And yeah these are definitely a little tight to work on
NoNonsenseKnowHow any possible way to get a exploded view of where this valve goes. Or maybe a replacement guide that tells the steps needed? I just don’t wanna go into it blind.
Yeah you might be able to look at some parts diagrams add a Mercedes parts website. Or call the dealer for a diagram. Might be best to just bring it somewhere for the repair if you can't find a video on it
NoNonsenseKnowHow thanks I will continue to look but not having luck finishing my model year. Called the dealer and they want 1200$ labor to start. I think I can muscle they it for that price
Hello did you ever figure out how to do this?
Thank you
Good information thank you.
I learned something new today thanks 🙏
Awesome! That's whats up
Who would have guessed! Thank You! God our Heavenly Father bless you 🙏.
Thanks Buddy, my car started making the same noise a week ago, now you saved me !! Does anyone know how to change the part?
Hi Carlos, did you repair it and what part did you change?
@@tawabafg111594 Hello, yes I replace the pvc valve assembly take me 10 hours, th-cam.com/video/OF9h3dqy2ZM/w-d-xo.html
@@tawabafg1115942015 MB GLK350 part # 2760100331 My case I install a Vaico brand # v302524
@@Charly-jj7uc thank you
I hope you charge for diagnosis.
so I have this problem on my Mercedes e 350... the dealership did a diagnostic test and came back with saying its a centrifuge crank case cover??? basically the same as you just demonstrated in the video... they want to charge me 2000 bucks to fix it.... what say you...when I look this up under parts I get a Crank case ventilation valve everytime... what say you...or somebody please help!!!!
U DA MAN!!!. THANK U BROTHER
No problem Big Sean
PAIN IN THE ASS TO CHANGE .. BUT DID IT.. BUT NOW I GOT A MISS ..... OH WELL AT LEAST ITS QUIET! .. THANKS AGAIN
Thank you for your help
I have the same car and same issue just started today anyone can tell me what the dealership price should be for full repair? By the way thank you so much for this video
Same noise and codes with my 2014 C300. Bought the PCV from Rock Auto..$45. Installed only the diaphragm cove, internal diaphragm and spring....old diaphragm had a small tear ...good as new.
Dealer wanted $580+diagnostics+tax...Thanks ...Saved me time and $$
awesome! good stuff
Thumbs up 👍 sent in. ✅

I have seam problems
Please 🙏🏻 let me know what you did to fix your car 🙏🏻🙏🏻🙏🏻
Thanks a lot
Wow, interesting. Would've guessed maybe a bad water pump, if not a belt. Now I know!
Yeah I thought for sure it was going to be a belt squealing on a seized up pulley. But once I heard under the hood, it definitely had a different sound to it.
awesome👍👍👍👍👍👍
Ya actually very common with German vehicles in general. Volkswagen, Volvo, BMW, and Mercedes. They all make that misleading sound that the pcv system makes when the valve fails. That noise is air getting sucked in thru the crank seal and like you showed the easiest way to diagnose it is the pcv system is to simply take of the oil cap.. On that car if you disconnect that line you were putting pressure on and block off both sides the noise should be gone. That tells you it's the actual centrifuge that is the issue.
Have to remove the intake and move the high pressure fuel pump back to make room for it.
Is it hard to replace the air intake valve? 2014 MB E350. Same issue. Squealing and as soon as I remove the oil cap it stops. Help!
did you ever repair it and if so what was the cost?
@@levibenavides6387it was about 600$ w a local mechanic
Replaced o line but still squealing need to get to PCV valve on 2015 GLK 350 any suggestions on an easy way to get to the part?
All the best stuff is made in japan
I am getting this noise recently on my 2011 GLK350 with almost 70K miles. Does some kind of error code message display on the dash? I don't see any on mine. Or do I just take it to a mechanic? The noise stops when I apply the brakes though.
I have the p2279 code air leak atm and I was suspicious about that part ama take it apart remove the whole intake manifold and find the cause .
What you find was wrong exactly??
I have a similar noise I can not figure out. However mine is mostly when cold and only does it when accelerating makes a chirping noise. I’m a technician but I can’t seem to figure this one out. Mostly does it when it’s cold.
try changing out the o ring
The noise you're hearing is air passing through the front crank seal due to high vacuum. Pop the diaphragm cover off the vent valve, remove the diaphragm and spring, cannibalize the same parts off a new valve assembly and reassemble.
Could you specified location of this part ? I have the same noise
agreed what and where are you talking about?
@@IamChmiel hi, did you end up fixing yours?
Im experiencing the exact same noise. Its not the belt or pulley. I havent checked the oil cap tip you showed, but if it does stop when its removed. What part are you suggesting needs replacing? I could'nt quite make it out in the video. I read a comment below and searched part number for Crank Case Vent Valve...but what then is the black tube youre pressing on next to the oil cap?
Yes it needs a crankcase ventilation valve. PCV. That pipe is more than likely connected over to the PCV
@@NoNonsenseKnowHow I called my local dealership to get the part number so I can buy the correct part for my vehicle and...they told me the crankcase vent valve is not the same as the PCV valve. As you stated in your video, the CVV is located near the firewall which the dealership concurred. But the PCV valve is located up front. Part number for the CVV for my 2014 GLK350 is 2760100331and is about $100. I found them on eBay OEM for $82.
A mechanic I use regularly quoted me $100 (labor) to replace the CVV. I'll report back when its done to let you know if it solved the problem.
@@yatesc9246 got you. Okay I really appreciate the update with information. Let me know how you make out! That seems like a nice price
@@NoNonsenseKnowHow GLK fixed. The CVV was the offending part. The total charge was $733, which included a set of plenum gaskets and a breather hose. Problem solved! And YOU saved me the $180 diagnosis fee. Thanks!
Awesome! Happy to hear that and I appreciate the update
Is it safe to drive like this?
We are on vacation about 5 hrs from home when this problem started
Well- we couldn’t get very far before the car was inoperable.
Had to get towed to Mercedes.
Diagnosis- centrifuge valve failure. 4-5 days to get part; $1400 to repair
Of course he didn't wanna pay haha
He ended up trading it in for a new car
How to get this hose off
I had a doubt on the same on my ML350/W166 which was coming from engine crankcase vent valve. Had a service recall recently and the technician said it’s the vacuum plate on the back of the right cylindrical head. Are you referring the same?
Yeah that sounds about right where it was coming from
Did you get a quote for the repair?
NoNonsenseKnowHow The part costs about $50 to $100 online but dealer has it as $142. The labor quote you wouldn’t believe is close to $1000. Of course it’s from the dealer. I think it’s a 4 hour job and the engine will need to be taken apart. Still it’s not worth that much of the cost in my opinion.
@@worldpeace5853 wow, yeah that is pretty steep. Not surprised to hear that though. Definitely looked like a pain in the butt
@@worldpeace5853 do you have a part number for what needs to be replaced? I can plug it in the description for people in the future
So I have the same issue on one of these... is the replacement hard?
Unfortunately I couldn't tell you since I've never actually done one. Hopefully somebody else sees this video and can post a repair video or one with some more information. Sorry I couldn't be of more help
I am a used car technician at a dealership, so I am just gonna start taking shit apart and see if I can get her done lol
@@regbravo6049 sounds like a good plan! Let me know what you fine. I'm very curious to know if it's an easy fix or not
(Update) this sucks, there is no room to work on it, and you have to remove the high pressure fuel pump.
@@regbravo6049 damn, yeah I had a feeling it would suck. That's why I wasn't too disappointed when the guy didn't want to fix it at my work.
I think I am having the opposite of this issue. I changed my crankcase vent a while ago so I know that is good but I have pressure in the crankcase instead of vacuum. When I remove my oil cap I see specks of oil kind of flick out and I think while the car is running it is forcing oil out through the cap. I also have a whistle sort of noise but not this loud and appears to be coming from the front of the intake manifold. I sprayed it with break cleaner and it goes away temporarily and the engine shakes a bit. Would this symptoms indicate a leak in the front of my intake manifold? I have the m273 engine and the manifold has gaskets on the side would it likely be one of the rubber hoses in front of the intake? I'm not a mechanic so I don't really know the names for everything so i'm sure my explanation sounds pretty bad but any help would be appreciated.
Since you said you said you changed the vent, that's where I suspect the problem is. I'm just guessing and playing the odds, so no offense, but people do screw things up. If somehow that vent is not actually letting air in, then you would likely have exactly the problem you described, which is a slight bit of pressure venting when you remove the oil cap, and a small amount of air steadily exiting. You should be able see it as a faint smokey vapor exiting, if the eng is fully warm. Another clue you have actual pressure is when under load it gets a lot worse and it'll push the oil dipstick out about 1/2" until it can vent from there. So push it all the way in, drive it, maybe floor it, then check the dipstick.
Or I could be totally wrong :p, but that's my #1 suspect. Whatever the case, post if you have fixed it, to help others out...
@@chevota400 i actually fixed this. It was the intake manifold…. the runner was kind of sticking giving me this noise intermittently. Good thing I caught it early even before any codes.
Owns a benz but doesnt want to fix the benz... Damn.
Yeah we run into a lot of that at my shop. I don't think he was prepared to spend that kind of jang that day. He thought it was just a belt...Which it really did sound like at first
One possibility is that the owner wants to fix it himself, but the filthy state of his engine suggests he doesn't spend any time working on this vehicle.
@@gkelly941 true
@@NoNonsenseKnowHowabout how much is it to fix a problem like this?
I found the same issue on my 2012 Mercedes-Benz c350 I was quoted $715 to get it replaced is that fair or am I being overcharged. Can you help me by just giving me prices I live in San Marcos Texas thank you Woody
That is about right.. got ours fixed in July.. it is extensive labor intensive for inexpensive parts.
Actually not a hard job but i’ve seen worse quotes on it, here is a diy for the GLK which is the tightest to get to in my opinion
th-cam.com/video/9jM8uU4pEx8/w-d-xo.html
I have this problem. And when I take off the oil cap the sound goes away. What’s the name of this fix? Or what needs to be replaced to fix this? Do I need to buy another oil cap? Or Also, can I just drive with the oil cap off until I get it fixed?
Did you watch the video?
Can we drive without the oil cover or we change the oil cover ?
That’s what I want to know can we drive it still an how farb
@@stevenmartinez8240 , I tried driving mine. It went about 60 miles before completely breaking and needing a tow.
4-5 day lead time on part from Mercedes and $1400 to repair (part was about $350)
People please don't get Europe cars if you cant pay the expensive parts or labor
