It's happening with the newer models (W206 - 2023), especially during accelerating (not always but sometimes). It sounds like it's coming from the wheel area.

In the first clip during launch, you can hear the detailed noise. I've asked others with the same issue, but changing the tires and cleaning the brake discs didn't help.

So, I'm thinking it might not be from the brake system.

The car was just released in January 2024 and has only done 3000 km.
