I am not sure what I am supposed to be hearing, are you talking about the knocking sound near the middle of the video? As the cover is closing, I assume you had recirculation on?

ANIA-SAY-HO:
I was able to listen to your video post
If that's the only problem, your fine: not a problem!

A long "tic-tic-tic-tic" for 1mn would be a known problem of hard flap not initializing.

Use a good MB scanner to see AAC Module faults and actuate the 5 or 6 flaps air-con uses.

That's good news, thanks forum member CaliBenzDriver for confirming to OP that it is normal and everything is all good!

No190 is one of the flap actuator.
Use a good MB scanner to see AAC Module faults and actuate all the different air-conditioning flaps.

When the vehicle stops, it makes a plastic interference sound, so I'm going to disassemble it 30 times or attach grease or soundproof tape to the coupling part.

You need a scanner to work on this system... the AAC system is always powered even with IGNITION:OFF !!

Disconnecting one of the flap actuator will cause a fault that may further disable function.

I advise you do not unplug anything with battery power active ie. consider DISCONNECTING BATT as the first step.

Without a scanner... the best choice is to let a MB specialist work on your car.
