No warranty. Any idea about the costs? Am I thinking of thousands of euros / dollars or more like 1000/1500?

Jimmy_c63s

Have a look at the link I posted above. Guys in Germany reporting about 7000€ was their bill so around $8500 USD.

Bear in mind that most of these fellas went through Mercedes dealers so an indi would be cheaper.

Better still, ask for goodwill at Mercedes. Escalate it and make them pay for at least half.

yeah man but that too was a blessing in disguise because it made me get the AWE Track exhaust. Warranty is up this summer so might upgrade to the 275/305 combo and get a tune.

Hi, got your visitor message. I posted the link above. Good luck.

Guys can you hear any weird noise? My engine has over 100 000kms, and 60000 with the tune..

thanks

Jimmy_c63s

I couldn't hear anything irregular, but could you take another video just a bit further back from the engine bay please? The sound we don't want to hear is the cricket sound of "tek tek tek tek".

In your video all I could hear was the normal injector sound but the video was a bit short and close to the engine.

FLC63s

agreed.. step back a bit, you can actually close the hood and film from the outside next to the wheel wells and hear it if it was the timing guides.. (the crickets)

Hello, can you all please also listen to see if I have the sound. I do hear a sound but it isn't exactly the same as the video Jimmy_C63s posted and its actually a little more pronounced when you hear it through your phone rather the computer.
Its more of a slight whistling noise then cricket/ tek tek sound.

Thanks!

FLC63s

thats normal

Jimmy_c63s

Yes yours is normal no problems at all 👍

The dealer said they found the problem, it's my fuel pump and they replaced it yesterday.
I know c63 w205 fuel pump is a common problem.

This morning with a cold start I can still hear that sound.
I'm going to test it again at the end of the day, if I hear it again I want an explanation from the dealer.

velosdesignwerks How did the dealer find out it was the timing chain guides?

FLC63s

This is the first time I am hearing of a Fuel Pump (common problem) ... but any ways.. understand this......
The fact that your dealership "found" or said they found a problem, is sorta suspect to me, as I didn't hear a clip of what sound you were referring too, but since you posted in this thread, I have to go with the sounds that most reported here and those by far were NORMAL noises our cars make. ( if you have a Chirp and or Cricket sound, then its possibly something more serious)

A Fuel pump noise (which are cars do make, and they make noises when they PRIME up for start, and so forth) can fail. and do fail just like any other part , more so if there was bad fuel or crap that blocked the hoses, and or added more resistance to the fluid flow that caused the pump to wear and tear more then normal.

If you want to go hunting for a problem, you are most likely to cause more then you bargained for......
What exactly is it that you are going to TEST ?? none of your post below make any claim to an issue, other then a SOUND, that was NOT as loud as others, and it went away after 6 minutes ??

In my opinion, dealership prob said / replaced fuel pump to get you out the door.. ( and since I dont know you, I cant make any statement to the adverse )

Just saying... IMO

Jimmy_c63s

No man it's not your fuel pump and has nothing to do with it. Your dealer is full of sh*t, don't let them stuff you around. That sound will continue to be there until the real issue of the timing again guides are sorted.

Exactly bro.

FLC63s

That is my point, but the poster didnt supply any sound clips, and he stated it wasnt the same sound as the Timing Chains... I think he doesnt really understand what he is hearing ,and is just "Freaking" himself out on something.
Hence why I asked, what type of TESTING he says he does, or what ever.. Our cars make all sort of noises, if you want to hear some crap to freak you out do this:
1) park your car
2) turn off car, remove key and just SIT
3) site nice and quiet for 2-3 minutes

During which time you will hear your car basically doing all sorts of crap ... all 100% normal.. same crap happens when you start up your car.. ( more so on an AMG)
Another reason, you just dont START and DRIVE, these cars need to warm up, cycle thru its checklist and get stuff ready to go

Djordy

Here's a video of the sound. By testing I mean just listening again at the end of the day haha.

FLC63s

Well that KNOCKING sound (if thats what your stating, is def NOT a fuel pump)

Jimmy_c63s

Good video. It's the timing again guides 100000% you can hear the chirping/crickets sound very well. It's very distinct.

How long have you noticed this sound happening in your car for?

FLC63s

10000% agree with you Jimmy_c63s , if I would have seen this video before, I would have said the same... Fuel pump my **** ...

Ksun_w205

Just wondering should timing chain guide and a belt squeal sound the same? I occasionally get a cold start belt chirp squeal but never a sound of this tone, rhythm, and frequency. Would you say a belt chirp is more like a bird sound while timing chain guides are like a hollow cricket sound?

I read another thread where someone had this issue and brought it to Mercedes and on their receipt invoice it says "We are aware about number of AMG vehicles with this sound. We assume, it is going from valve gear (chains?) Customer need to know, that this annoying noise doesn't harm engine, nor performance of the car. As the car is fully usable, your service stuff can reassemble car and it can be given to customer. At this time we have no solutions for it, but we will inform you as soon as we find it."

Jimmy_c63s

That's fine the squeak is your pulley and accessory belt needing replacement soon. Even after replacement you will still get the occasional squeaks on cold start especially if the car hasn't been driven for a few days or after heavy rain (as mentioned above in this thread).

The timing chain guides sound, as you described is that distinctive, hollow, cricket sound of tek tek tek tek on cold start. That's the bad one.

Just to be clear so far on M177 noises:

⛔ Timing chain guides: Cricket sound tek tek tek tek that disappears after about 5 minutes after cold start (Bad, Urgent & Expensive)

✅ Injector sounds: Tick tick tick tick sound especially louder on right side of engine when standing in front of the hood (No issue & Normal)

✅ Belt and pulley: Squeaks which usually disappear after car is warned up (Fine & Not urgent)

CRAP! I think I have this cricket noise!!

George_1992

nah?? U sure....... how long have u had the noise for?

amg8

Is this the cricket noise?

Jimmy_c63s

No that's your belts/pulleys.

amg8

hmmm sounds about the same as the videos above? Where's the distinction? Also is this normal for only 25k miles on the clock?
