w205 - c300de - Back end noise

Hello all, I'm new to the forum.

I own a c300de van I belive the code is w205(I posted in w206 by mistake), still under warranty.

The issue i'm facing is when driving normally the car handles fine and makes no noises regurarly.
When for some reason the front end gets lower than the back end the back end makes a squeaking noise.
If i drive above 10/kph on a traditional stone road like "roman roads(don't know the english name)" the squeaking is consistent from both wheels at the back.

I took the car to the shop under warranty they drove with me and also agree and ear noise from both wheels.

The checked all the suspension and tell me there is no danger to drive the car, but they can't identify where the noise comes from. At this point they tell me they will get a "noise machine" so they can see where the noise comes from, and assured me that they checked every suspension part and all is fitted and bolted correctly.

My questions are:
Do I have any chance of this noise going away with the machine they are bringing ?
Anyone had a similar issue or idea of what could it me ?

Thank you

The car is under warranty. Get your dealer to fix. If the dealer didn't know what is wrong with the car who will know? Its his responsibility to fix the car once for all you don't have to keep guessing. If I were you i would ask th to give me a courtesy S class untill they fix the car. 😁

They wont give me a courtesy car cause the car can be driven without any safety issue, that much they gathered..
