Clicking noise from rear
2022 w 57k mi. When driving w window down I noticed a clicking noise coming from rear after coming to a stop and then start fwd motion again. It was subtle that w windows closed and music I did not noticed it before. After looking further (driving only) it happens when taking off and slowing down. Best way to describe it when you have some play on a gear set and you turn one way takes a bit to engage and if turn the opposite way same thing. No grinding at all. While constant driving is smooth as always.
Searched for similar here and nothing on gls450s (that i found), but there are a few hinting to breaks, axle, and miscellaneous possible reasons like a nut holding the wheel bearing.
anyone with similar issues or diagnosis? and possible fixes? Ideas?
I am trying to narrow it down before I lift it in my garage or before I take it dealership.

It is mainly caused by a weird calibration issue MB had on newer model years I think starting 2023 or was it 2024, I also heard reports of those (2023 or was it 2024) model year vehicles might not have this camera pop out like that prior to a software update, so fair to say, the software update might be the issue, MB however states it is intended behaviour (at least the dealership).

You're welcome : ) I see, then you might not be affected by it but the symptoms described is very similar to what is reported in that thread, hope the dealership will figure it out and hope things work out in your favour.
