Engine sound

[@yacuilaa]

Everybody stop with thinking! I had this problem on a m278 engine. The m157 amg engine is the same engine but only a 5.5 insteed of 4.7! This is the sound of a (tilting piston in cylinder due to scratches in cylinder wall) Engine is done…. Needs new engine

[@maxtay63]

Did you ever find what the noise was ?

[@hazemhamada1638]

sir after your inspection , what was the reason behind this sound !!!!!!!!

[@mitevkrisztian1376]

My E350cgi does the same noise occasionally. It goes away and comes back randomly. When it does it only does at idle speed, sound disappear when engine revs up so it`s surely not mechanical component inside the engine, otherwise the sound would be more louder as rpm goes up. I think it`s fuel injection related...could be the high pressure fuel pump is on its way out or contamintion anywhere in the fuel line.

Hi Tasos, I’m a Mercedes tech in the USA who just bought a 13 ML63 with 110,000 miles with the same exact sound. Mine is currently 100% stock. I’m very interested in what you find. Hopefully for my sake, it’s not bent rods. You truly have a understanding of these engines and a high attention to detail that is missing from most of the shops out there. These videos are usually far more informative than Mercedes training videos. Nice work

s600biturbo did you find the problem? My 15 s63 is making the same sound

[@jurgeenhandazola3006]

¿Do you find the cause?

@@s600biturbo were you able to find the problem?

[@mstoddart9947]

hoping this doesn't get lost and im sure you have had many cars come and go since, but i was wondering if this was ever sorted out or if the customer figured out what the issue was. I am having the exact same sound coming from my E63, downpipes and tune as well. my gut reaction was rod bearings but the sound is so odd and randomly goes away. Hopefully you might have an answer, if not i appreciate it anyways the video's have been incredible! thanks again!

[@vietstudmuffin]

Hi brother, were you able to find out what was wrong with the car? I will appreciate any response from you.

[@ahmedhamidullah3486]

Were you able to figure out the issue? Same sound with my cls63

[@AnontheGOAT]

Mine does this when in gear. But when in Park or Neutral, it's gone. My guess is the dual mass flywheel. Several other comments on youtube and on the web say the same thing.

[@emmanueltomlinson5776]

Did you find a solution?

[@AnontheGOAT]

@@emmanueltomlinson5776 nope, other than what I said. Sold the vehicle a few months ago.

[@ChrillJH]

Hello! I have the exact same ticking sound from my cls63 with the m157. It doesnt tick the first 30sec after a coldstart, after that it starts to sound quite loud. After driving and getting the oil up to around 90-100c its almost quiet. I have searched like crazy without any answers. I have tried changing oil and doing a engineflush without progress. Is there anyone that has had this problem and found a solution? All answers is appreciated, this is driving me crazy. Thanks

[@xiSevenHD]

and now ?

[@walid9168]

I have the same sound, is the problem solved? Or what is causing this sound?

[@emmanueltomlinson5776]

Did you figure it out, has it caused any problems?

[@vietstudmuffin]

Hi Tasos, so did they car ever come back for you to diagnose what happened?

[@persnngtr3255]

If it's coming from the bottom it sounds like a two mass flywheel. But I'm guessing that people who are more experienced than me would've checked it. But interesting. I was recently planning on buying W166 ML63 tuned, but didnt buy because the car had exactly same ticking noise, maybe even little louder.

[@jurgeenhandazola3006]

¿Do you really thinknis the flywheel?

[@persnngtr3255]

@@jurgeenhandazola3006 I really don't know. but if it's coming from the bottom and if it ticks faster as the RPMs go up then flywheel would be the first thing I would check. But then again, I'm just guessing. disks inside tend to become loose and they make that ticking noise. it seems like a lot of ppl are having the same issue but nobody has figured out what it is.

[@jurgeenhandazola3006]

Removing the transmission just to check up is expensive, I was thinking to remove the engine oil pan and check the bearings, also replace them if they're worn, maybe that fix last for a while.

[@persnngtr3255]

@@jurgeenhandazola3006 good luck. Let us know if that is the issue please. Thanks

[@TripleCMotorSports]

Did any one find a reason to this sound> my 2013 CLS550 is making the same sound

[@maximorar0918]

Someone have the solution?

[@carlostosado8086]

Has anyone figured this out yet? Lots of people with the same exact noise and no answers. Pretty ridiculous that so many people have this exact sound and no one can post a logical explanation not even the king of m157 himself has zero input.

[@chuemoua6834]

That noise is the piston rocking inside the cylinder . Master tech in Mercedes right here

[@RayRocketSSTurboX]

Hi Tasos, My M278 got the exact same sound. The car was always carefully driven by my father, but he had no moment for checking liquid levels etc. As I took a look back in 2017 there was a huge lack of engine oil! I filled it up but the sound never got better. I even tried changing the oil to a Mobil 10W60 racing oil which didn't made it any better - after that I put in some Lucas Oil Stabilizer - the sound was not getting better anyway. Are you opening the engine now to find the problem or whats the plan? I even mentioned that the power delivery is getting worst by time. Your Videos are mega! Proper work! I wish someone like you would work in Switzerland!

[@xiSevenHD]

my c63 got the exact same sound too

[@thommen-furlerag3761]

Does something happened in the meantime to this engine? What was the fix?

[@TasosMoschatos]

Thommen-Furler AG hi, nothing up to now, if the customer bring back again his car I will make a video. I hope to be wrong and to don't have any issue his car. Thanks

[@RayRocketSSTurboX]

Tasos Moschatos In the meantime I changed all Spark Plugs, all were looking very clean and dry except cylinder 4 at the passenger site! Spark plug full of oil... Think I need to take out the engine!

[@oda0111]

I have the same thing on my M273, not as loud. I've been having if for the past 21000 miles, I've done oil analysis and everything is fine. There is no excessive metal debris in the oil, no smoke on the exhaust tips, no vibrations, the fuel consumption is consistent with what the manufacturer specified and the sound hasn't gotten worse over the past year and a half. I am curious to see what causes it, on mine it seems to be emanating from between cylinders 2 and 3 on the bottom half of the block, towards the engine oil pan. I've also heard this type of sound but somewhat muted on W212 E63s, even on new vehicles. Definitely let us know what you find out about this issue. Good job on the videos, I learned a lot of things watching them! If you ever come to the States I'll treat you with some good Chai.

[@bassammohammed9209]

@@TasosMoschatos hey , did you please figure out where this sound comes from? My cls63 m157 has the same issue and nobody has an answer.

[@osebgee]

@@TasosMoschatos hello, have you any idea what sound this could be, a few places including Mercedes don't know, no codes, no issues just an annoying noise. Sounds like its up the top to the rear if the engine near the fire wall on the right as you look at it from the front. Low idle no noise, high idle sometimes noise only when warm. kzbin.info/www/bejne/o2HGgp2njrt4m9k 2015 E63 70k miles

Hello, I have the exact same sound on my car, it is a lot more louder when in D and R but it also in P and N. Mine was never tuned and never had any mods. It is weird that so many m157s have this

[@jurgeenhandazola3006]

Also M278 engines develop this noise, I'm seriously thinking to remove my oil pan and replace the rod bearings to see if i have any improvement, also I read some guys pointing to the dual mass flywheel.

[@AnontheGOAT]

@@jurgeenhandazola3006 Mine does the same exact thing. Sounds pretty much goes away when in P or N, but when in gear, it's audible. Found several comments around the web saying this is the normal sound of the dual mass flywheel.

doesnt the car usually make ticking noise.....having trouble differentiating exactly which sound u are talking about....

[@TasosMoschatos]

Faiz Rahman this is exactly what I'm talking about and what I'm trying to explain to some people that they are sending me videos and asking what is this sound, I'm not blaming them, they just trying to understand what's going on. On this engine you can hear the sound of the high pressure pumps and another sound that's coming from the bottom end of the engine.
