Hello, I'm a person who is interested in DIY living in Korea. I've been under stress for a while trying to find the cause of the noise, but I don't have a part code or drawing, I want to see the epc wis, please help me.

 

Are you able to record the noise you are talking about?

 

..
i have mp4 video

 

You may upload to youtube or an online drive software for example dropbox then link it here.

 

Convert the mp4 to mov format online (free) then attach the mov file to your post.

 

Thank you all
Please listen to noise...

Hmmm, don't see the link though.

 

No file is attached.

 

We are now able to see your video.
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!

Can you tell me the service manual? With the code

 

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.

After removing the blower motor this weekend, I'm going to do it with soundproof tape or Vaselinebh
and The background music is the sound of the parking lot, but would it be a copyright issue?
