Help needed about the noise from suspension

I have been driving my S350d (v223) for nearly six months. Recently, I noticed an issue with the suspension when driving over slightly uneven roads or speed bumps. Interestingly, this problem only occurs after the car has been driven for at least 15-30 minutes, leading me to suspect that certain suspension components might be affected by heat.
I have taken the vehicle to the Mercedes-Benz dealership multiple times, but they have been unable to identify any issues. They attempted to replace some spring links, but the problem persists.
If anyone has experienced a similar issue, I have posted YouTube videos with the accompanying sound here. I would appreciate any insights or resolutions you could share. Thank you.

I shared the videos with them and attempted to do the same with other Mercedes-Benz dealerships. Unfortunately, they were unable to determine the root cause of the problem. They have replaced the front left air suspension, but the issue still persists.

Not to let anyone off the hook, but it can be difficult to figure these out. Persistence is your only friend coming out the gate. I'm not sure whey they're reluctant to keep at these things, but they do seem that way, and not just at MB. In any event, you have little choice but to live with it, or go into squeaky wheel mode.

As you mentioned, it is quite frustrating. This issue tends to occur particularly after driving for a while, more than 15 minutes per se, or when certain suspension components become warmed up.

Did they use chassis ears to try to assist in determining the issue?

When I picked-up the car from the dealer, the technician told me that if the problem persists, I might need to come back to replace the right airmatic absorber, because MB did not approve for both sides to be claimed at the same time. The technician was told that the car was too new for such claims.

To be honest don‘t they have a better way to find out the root cause?

The sound originally came from both sides (as the technician told me), but the left was more noisy than the right. They installed some special equipment per MB‘s instruction though to record the noise, and sent it to MB for warranty‘s claim approval.
