Hi, Everyone

I have a 2022 GLE350. I found my car made a noise while I was driving.

The problem is that after a cold start, there is a clicking noise when I am accelerating. The noise is heard most clearly at speeds between 15 and 25 MPH.
It can only be heard when I am accelerating in Drive; when in Park or Parking in D, I cannot hear it. Even if I hit the gas on P, I cannot hear the noise.
The noise disappears once the oil temperature goes up. The colder the weather, the louder the noise.
The car is still under warranty, and I have been to the dealership's service department three times. They checked the car's computer and said there is no problem with the engine.
Does anyone know how can I solve it? Thank you.

Regards,
Daniel

Here is a video of the noise, but in reality, it sounds a bit different from what is heard in the car.
The noise is more like a hitting sound, as if a metal wire is hitting a thin metal slice, or a metallic friction sound.

Sounds like the wastegate rattle.

You are talking about the playing cards hitting bicycle wheel sound right?

But I can't hear the noise when I hit on the gas in P. Does the wastegate only rattle in d?

Not much call for turbo boost when you are in P or N. The info screen will display boost pressure. Does this change when you are hearing the noise?

It shows 0 all the time.

Wastegate rattle happens mostly when vehicle is moving at speed.

It shouldn't show 0 when you are driving the car.

My bad, I took a drive yesterday and noticed that the numbers would change when I hit the gas harder.
