AC off, heating wheel all the way to cold, inside temp to match outside.
The blower motor is rulled out since the noise stops immediately as the AC is engaged.

Went to BMW for a paid diagnosis and they didn’t “notice” it (most likely they engaged the AC)...
I’m kind of stuck with this, any help is highly appreciated.

Wishing you an excellent weekend ahead,
This sound is driving me crazy, the only information in the original Youtube video is that some hose was changed, but wich one????



I can't believe that after so many people involved nobody remember the info!!!
