Rattling noise during heating operation (with audio)

[TM3A]

Hi, some M3 drivers including me, have the following noise sometimes in heating mode (please listen to videos), manual mode without dehumidification (AC off), only heating the interior with a heat pump (please download videos.zip, extract and hear).
Tesla cannot/does not want to provide any information about the noise in the video. I would have to take a day's vacation and drive 200km to the center, but then the noise probably wouldn't occur.But since several M3 drivers have it, maybe it's normal?


Greetings.

I have the same. I didn't have that last winter, I think it occurs since 2 weeks ago or so.

hmmm, no body else?

Btw do you know how to "reproduce" this issue? On what conditions it's occurring? Right now, I don't hear it, so I guess it has to be cold enough (here in Poland, the temperature has risen above 0 Celsius lately).

I'm asking because I'm thinking about reporting it via the Tesla app.

yes, only if "AC" is manually turned off as I wrote: "heating mode, manual mode without dehumidification (AC off), only heating the interior with heat pump."
here you can directly look/hear that noise:

today it is 7°C and in "auto mode" (with AC on) there was no rattling noise, then I switched to "AC off" - wait some time -> rattling noise.
