Looking for any ideas as MB techs seem clueless
Hey everyone,
I don't own a C63 but a 2019 C43 (but I do hope to one day...so I'm a little jealous of all of you) but I am looking for any ideas or help from other MB owners as I am getting an odd "grinding" noise that only seems to happen when the boost gauge recedes and right before blow off. I am hoping any of you may have heard of or experienced this noise. I have K&N filters in and besides that everything else is stock.
I put my GoPro inside the engine bay to record the sound. You'll hear the noise around the 4 second mark.
Mysterious Grinding noise:
Timeline since November 10th with local MB dealership here in Calgary trying to fix it:
- Replaced drive shaft centre bearing and rubber mount
- Replaced the left turbo charger assembly, diverter and right side diverter
- Replaced the front axle propeller shaft assembly
- Replace intake and exhaust cam solenoids
- Replaced transmission assembly without the torque converter
- Replaced transmission torque converter
- Replaced flywheel bolts
- Replaced front propeller shaft bolts
Noise is still present and is getting worse which has been acknowledged and confirmed by technician on January 5th 2021.
Not sure what to think anymore and they still have no idea what is causing the noise.

Hence why I’m looking for any ideas as they don’t seem to have the slightest clue as to what is causing it.
If you can believe it the last thing the tech checked on Friday was the windshield wiper blades....HUH!?!

nope...no more to the story. These are all the items they’ve replaced in hope to fix the abnormal noise and after all this time, shop hours and money the noise is still there.

Very weird that they do all that to fix a noise like that. Can't blame them for not trying. I think it would help of you systematically figure out when that noise happens to narrow it down. From the video it sounds like when the car is shifting up but that may not be the case. Therefore taking videos at various drive conditions and record them to correlate when it happens may give the tech a glue.
As for when, it only happens on partial load, slow boost increase and when the boost recedes right before the blow off (you can hear it in the video).

Time to take that info, together with the long list of what did not fix it, to a new shop. If it happens right before blow-off that should tell them a lot what it may be and more importantly what not.

Agree on the C63 noises..with my ZAC's and open BOV's it makes all kind of sounds and I don't try to listen to carefully or I would just get worry - it's a noist engine. My wife called it a snake from all the hissing and blow off noise.

I would expect the original MB tech was expert enough to determine that noise is not normal.

Techs will swap an engine out for the warranty money they get on labor from Mercedes.

With my C43 I had techs that could not identify the source of certain noises period. Another tech from another dealership identified it in a heartbeat.

Sometimes the dealerships really do try to take care of the issues for you but sometimes the shop foreman just is not experienced enough to find the issue on their own. Tell them to open a ticket with the mothership (i.e a TIPS case using Xentry). If they still cannot figure it out try another dealership.

I think the plan for me now is to bring it another shop...as I do think a fresh set of eyes and ideas is needed at this point.

Yes they have definitely put in the time and tried. I know they mentioned the other day that they have opened a TIPS case but no help or word from the "mother ship" as of yet...which is extremely disappointing since this all stared back on Nov. 10th.

Hey everyone,
I don't own a C63 but a 2019 C43 (but I do hope to one day...so I'm a little jealous of all of you) but I am looking for any ideas or help from other MB owners as I am getting an odd "grinding" noise that only seems to happen when the boost gauge recedes and right before blow off. I am hoping any of you may have heard of or experienced this noise. I have K&N filters in and besides that everything else is stock.

I've listened to your video about 10 times and I'm really curious what that sound is, it's almost like something is engaging and disengaging. Or something is rocking back and forth as it goes "cruck cruck cruck" and the boost ventilates after. Now I'm stressed, is there anything that's loose inside the engine bay? Something that's loose with the piping? I'm scratching my head but almost sounds like the wastegate actuator because it's making the sound when you're coming on boost then disappears after it vents.
Have you shown this to the foreman? Get him to sit in the car while you drive it and it makes that noise. I tell you now, I would go mental if that was my car making that noise. C63's aren't that much better when it comes to these types of things so trading it in would just start a whole new saga of problems. I've had every noise you could imagine in my Coupe and still trying to get to the bottom of it. My latest noise problem is here.
Let us know how you go.
