Cracks and crackles Interior driver’s side

All those who have noticed crackling noises in their EQE or EQS from the direction of the dashboard or / and driver’s door and have an explanation for it. In any forum post I read about it, but I can’t find it again using the search function. At first I didn’t notice any noise in the interior, probably none were there either. But now, when the car is cold, it crackles and crunches from the left dashboard side or / and from the driver’s door panel (see bi ld). After a while it stops, believe if the car is warm. I tried to push here and there during the ride, or even plug the tempos into cracks, in order to get the sounds on the track, but unsuccessfully. The workshop can (or does) not help either because the twitches only with the shoulders, as if they had never heard of it (do not believe that I am the only one, but this behavior is such a well-known tactic). (approx. 40 km) the car is warm and the noises are gone. I noticed the noises of crackers and knarz only after I picked up the car from a MB branch, to which the plant in Bremen had sent 3 fitters for 3 days to free my car from any remaining defects, with which the car was handed over to me when picking up in Bremen. This also included the armrest exchange in the driver’s door. I have to add to “failed” defects that it has already been in the workshop of my dealer was where a new roof sky was missed, for which also the rear window had to be removed (the delivered sky had a 3 cm long crack) and the A-pillar covering on the driver’s side was removed and reassembled, because a metal clip stood out from the joint to the dashboard -see picture-). But that cannot be the cause of the noises, because after that there was no notice.
