thank you for this video, i have an w204 2012 and i was hearing some little noise at first, then it went like the car in the video, the noise was very much and i remembered this video.
I'm hoping to spread the word. If u have a 2012-2014 MB C-class and u have rattling sound and ur mechanic think it's the timing chain, call up ur MB dealership and get it diagnosed and fixed. The repair will be completely free. The timing chain issue is related to the camshaft adjuster issue, and it's part of the camshaft adjuster recall, in which MB corporate has extended the original factory warranty to 120k miles. So if u have timing chain issue, the camshaft adjuster is prob an issue as well and ur local MB dealership will repair it for free. I just had mine done recently.
@@joiofjenz As far as I know C-class and SLK-class. U should've received recall letter in ur mail, if not then likely ur car isn't part of the recall...
It’s a great video, but you missed the most crucial part of the rebuild. How you actually got the cam shaft back in, how you set the timing, how you got the tensioner back on and tension on the chain. This is the meat and potatoes of the build and it’s unfortunate that in such a great video you missed this.
Yep this is exactly what my gmc terrain was doing. Idiots at the place I bought it from said it was the throttle body and then had me continue to drive it assuring me it was fine. Now I need a new engine and only had the 12k car 4 months.
Damn, the two times my throttle body went out on my Malibu, my car would shake horribly if I went over 20 mph. My car physically couldn't. So idk how the mechanic would say it's fine to drive
If the chain is stretched it would rattle at every start up. Imo. Might be wrong. But i just had to deal with mine , changed tentioner with no luck. Than i crossed a tip on a forum that pick up tube oring in the sump might be bad. It was completely flat allowing to draw air with oil especially on cold days woth thicker oil. Changed that one and no more rattle. $5 part and few hours on garage floor and done!
Good job and fairly easy to do with this engine unless one slide rail has to come out. Then the engine would have to come out, as already described here! I just happened to have the injectors out on my W204 CDI 200 and then took the cylinder head cover off to inspect the chain, spur gears and camshafts. Everything is still super top, the chain has not been stretched, the sprockets and camshafts have no visible wear ;-))
I had this noise more persistently. Apparently something to do with the turbo watergate. I’ve driven about 30k kms and nothings happened, I also heard of a guy who had this noise nearly all the time and drove over 100k and it was fine. I don’t know for certain, but see if you can recreate the noise. Try get your ear down near the turbo side and see if it’s any louder. Not sure if it’s definitely that but it seemed to be what was causing that noise on my car.
Nice video brother how u know what different between timing chain noisy and dualmass flywheel noisy i have Hyundai i30 2016 automatic gear making noisy is only 44067miles please
How much it would cost? Thinking to do it on my merc too is the exact same model, there is no rattling noise but I want to change the chain tensioner and sprokets just is case .
I have an intermittent noise on idling on my 2013 SLK AMG and no one including Mercedes can solve the problem it’s only when the engine has been running for 20 mins or so and not all the time only occasionally it’s fully serviced no expense spared and runs like a dream otherwise ! Drives me mad 3 years of it now
Thanks I’ve not heard it for days now it is only a second or two when I do anyway I forget about it and if the radio is off and I hear I only remember it then ! It’s an annoying gremlin that appears rarely !!
I sounds like it could be a frequency noise. Odd noises that only appear rarely can often be a frequency noise. Let me explain. Just like tuning a radio, you have to get the frequency on your radio just right to receive the radio station of your choice, turn the dial a fraction to the left or the right and nothing. Often on cars you will have a loose bolt (The heat shields behind the exhaust is a common one.) that will cause something to vibrate and make the noise. It will only vibrate at a certain frequency, this frequency can only be achieved when the temperature is just right, the engine rpm is just right and sometimes even the air humidity can play a part. I have a 1991 Land Cruiser, never had a vibration until i fitted a new exhaust, now the running board will vibrate but only at certain times. I have changed one of the parameters that was required to hit that frequency.
I have no noise on cold start. I only have an iron level noise at low rpm when I accelerate, once I let off the accelerator it disappears, or it disappears after 2000 rpm what can it be
why would the engineers put the timing chain on the back side of the engine? Sounds like that completely makes the process of replacing much more time consuming and difficult.
They had to make an engine with the same harmful technical characteristics as the chain breaker bmw n87 2000. BMW and MERC have agreed to build vehicles that are beautiful and deliberately expensive to repair… (if you think about it, they are similar in concept). Mercedes needed a drive gear between the high-pressure pump and the camshafts that could do everything with maintenance-free gears. Customer MUST EXPENSE for maintenance.
My e class has only done 47,000 kms and the engine has this symptom on morning starts and hot starts when rpm is below 600 is this normal? doesnt feel normal to me, considering the car is only 40 odd thousand kilometers in!
When the engine is cold, the oil is thick and takes time to circulate fully. This can lead to low oil pressure in the timing chain tensioner. The tensioner relies on oil pressure to keep the timing chain tight against the sprockets. If the oil pressure is low, the timing chain might have some slack, causing it to slap against the guides.
I have this problem as well with my W212 2009. My mechanic said always that the noise was not that serious to do an intervention. At the end I got a broken guide: a small peace was visible in the chain when the cover was removed. Now my mechanic says that in fact even if the guide has lost a small peace of it, it is not really necessary to replace the guide together with the chain. His argument is that if the new chain is installed, it will never touch the guide any ways and so the risk in practice near to zero. The local Mercedes would have said that they never replace the guides neither, but I dont know whether they don't do that even in case of partially damaged guide? My question is: Is my mechanic right in his reasoning regarding neglecting the guide replacement in case of small damages? What would be risk? Why should I replace the guide in case of damage?
Great video how many miles? You would think mercedes would be more reliable for the high price they seem to have engine and electric problems the worst possible problems piles of ....
2016 mk7 gti. I posted a video on my channel … when I start the car it makes a rattling noise but goes away in a couple seconds. Any idea on what it could be. I know it’s hard to say by listening to a video. Just trying to get any idea
Tsb says no consequential damage expected. So it's not necessary to do check valve and tensioner upgrade? Or is it just Benz trying to downplay the problem?
The latter. MB will never admit to this problem and my garage does not admit it either. They have been told to deny it as people at my dealer have said "the chain on these engines don't need replacing"
So if the camshaft sprockets showed wear and they were replaced, then the one sprocket down below on the crankshaft is worn as well and should have been replaced also, otherwise it will eat the new chain and this repair is very shortlived. There is a reason why the dealerships will change everything and not just something.
From an engineers perspective it's actually the best location for the timing chain. Much less vibrations (hence less wear) and due to the fact that it's a very short chain, there is also much less wear. Unfortunately the bookkeeper took the remaining minimum required strength as an advise and decided a little cheaper would still work...
No one replacing the water pump................bad move. Yes, it would have cost more, but it will costs even more when it goes, all will have to opened up again.
Thanks ... Now i know whats going on with my mitsubishi... I really hope my mecanic don t say something else . u know . a lot of times they re cheaters
I measured my new chain before fitment then my old stretched one. It was 12.5 mm longer. Almost one link and a half.!! 70000 miles. Oil changed twice a year. Utter garbage quality merc genuine chain
All European/German cars have good performance but only for short term. I feel like they were designed for quick performance but not for longevity/ reliability. They want to get people coming back to their workshop for hefty repairs!
Excellent video. A guide on how to set the timing would be really nice!

My e class has only done 47,000 kms and the engine has this symptom on morning starts and hot starts when rpm is below 600 is this normal? doesnt feel normal to me, considering the car is only 40 odd thousand kilometers in!
So, why does the rattling noise stop after a few seconds ?
When the engine is cold, the oil is thick and takes time to circulate fully. This can lead to low oil pressure in the timing chain tensioner. The tensioner relies on oil pressure to keep the timing chain tight against the sprockets. If the oil pressure is low, the timing chain might have some slack, causing it to slap against the guides.
I think you should have shown how to use the tool to remove the reset.
how is the kilometer?
After diag of timing chain issue how long did the repair take ?
I have this problem as well with my W212 2009. My mechanic said always that the noise was not that serious to do an intervention. At the end I got a broken guide: a small peace was visible in the chain when the cover was removed.

My question is: Is my mechanic right in his reasoning regarding neglecting the guide replacement in case of small damages? What would be risk? Why should I replace the guide in case of damage?
So what did you do? If the guide is breaking up it will be going into the oil supply - could block / damage something else
Thought you need to put brand new chain? Why fix old to new?
Lmao
He only joined the new to the old to pull it through! Otherwise the engine would have to come to be able to remove the cover!!!
Pay attention!!

For a vw its 400 i think so from a dealer maybe a grand
how do I know is not a VTC valve instead of chain?
Chain can last millions km!! It’s VTC and injectors nozzles!! They are thieves because the sound call chain 😂😂😂

Changing chains on these engines is a con job. Never recommend by manufacturers and chain should never be tight 😂😂😂
Help my car is doing this
had this on e250 soft top even put the ecu light on timeing marks were out got away with just chain and tensioner
How much did it cost you to repair
@@sophiea453 good £1000 but more if you might need to replace the cam phasers around £1500

There is a reason why the dealerships will change everything and not just something.
That sprocket has a contact with the chain on 3/4 of its circumference so possible that's why it won't cause any problem if you're not replacing it.
