The noise makes the two dampers is detected in the glue that bonds the damper to the chassis, the mechanic tells me he has to settle and disappear within a month, but this does not convince me.

As stated previously - look at your ball joints, toe-rods and control arm bushings. Rubber related squeel can come from few places. I can vouch for Arnott as I just had 2 front air-struts (the whole unit, new not remanufactured) installed in my Range Rover and quality of their workmanship is amazing.

The screw marked in red moves to turn the steering wheel and the rubber marked in green is what makes the noise inside sides

I believe this called strut mount assembly.. Are those components new?

The neumatica balona is new.
The damper is new.

The upper strut mount look old. It's part number 31306779604. Looke like someone did a Bad paint job in the engine bay. The paint is flaking off the strut mount assemby

The car never paint inside the engine. I have been the sole owner.
Only the original dampers were changed six years ago on the official service BMW.
I do not think the piece 31306779604 replacing.
Tomorrow I ask the mechanic.
Thank you very much to all.
