In early September 2020, I purchased the Mercedes-E-Class Perry All-Model E220D diesel vehicle as a new car at the end.
My family and I have a lot of mileage, so the vehicle I've been riding for two years is also a diesel vehicle, so it's really positive about diesel noise.
The Korean service center has not been able to fix it for 8 months. They don't even know the cause for 8 months. I'm so stressed out. I don't like Mercedes.
That's the noise from the engine room noise.
However, 3 months after the release (about 7,000km), there was interference in the engine room, like a trembling noise.
Crickets, bells, or iron plate tremors occurred.
As a result of grasping the conditions under which this noise is generated,
During hot weather, the cooling water temperature rises to 90 degrees Celsius and the noise occurs when the engine heat is sufficiently received.
Noise spreads through the driver's wheelhouse when the RPM is less than 1000, that is, when idling less than 20 km, or when idling.
If either of these two conditions is not met (e.g., 1000 rpm or more during cold), no noise is generated, and
Even if the conditions are met, there may be cases where there is no noise.
The noise disappears after about five minutes.
As you can see in the video above, the noise...
In the picture, press the 1st and 2nd parts with your hands or press them with a driver to stop the noise.
And the noise stops even when you touch the intake pipeline under 1.
Therefore, I visited the service center several times from January to August 2021.
Not only did the results not get fixed,
Service center officials, including service center advisors and center heads, thought the noise was a problem from January to August, but
The answer that recently returned after a face-to-face meeting with Benz Korea's Benz Korea specialist technician is "Just ride it because it's a normal diesel sound from a German manufacturer."
(Maybe they're forcing themselves to guess where they are)
So, on the Mercedes-Benz side,
1. It's a normal sound, but why did the noise occur three months later?
2. Why does the sound stop when you press a specific part, but how is this a normal sound?
3. Don't you think it's normal to tell us where the sound is coming from?
4. Why isn't this sound coming from a lot of the same cars, even from an 18-year rental cars!
I asked these four questions, but the answer that came back was, "I don't know the cause~ It's a normal sound from a German manufacturer, so just ride it."
With this symptom, when you go to the service center, Benz Korea and the service center talk to each other through "Tips".
No matter how much I think about it, I don't think this sound is normal.
If it's a normal sound, it always makes a sound, and even if you press a certain part, it should continue to make a sound.
However, pressing a specific area stops the sound.
It sounds exactly the same whether you touch it or not. It sounds like a diesel engine?
I think what you have, and why sound stops when you touch it(even though it doesn’t come through on the video) is rattles of materials… plastic parts that vibrates and gives of sound because the dampening material is insufficient.

I don’t think you have a mechanical problem
Agree.
OP, I viewed your video and everything sounded rather normal for an OM654. The reason why you only started hearing it recently it is because things are becoming loose especially some plastic parts as stated that has more room to "move around" post break-in, if you go over lots of pot holes, things might had became loose because of that, I don't think there is anything to worry about because most likely the loose parts won't affect the safety or functionality of the vehicle. Not to mention, plastic makes all sorts of noises when it comes in contact with things especially when things are moving like when your car is started and the engine is running, causing vibration to these pieces. Depending on how sound waves travel and bounces, it will sound differently. Think of an musical instrument if that helps explain it.
