W205 Motor Like Noise with AC
My C200 W205 has a strange motor like noise when turn on the AC. When I turn on the climate control along with AC, the noise comes within 1-2 seconds and changes with engine rpm. Even when I turn off the AC (blower still running) the noise persists.
The weird thing is if we just turn on the climate control without AC in the first place, There is no noise. If we turn on the AC then noise starts again.
I have attached the video below.
Thanks!

Exact same issues even after replacing compressor
Was looking around diff forums but found this post, i had the exact same issues just that it includes bubbling noise when idling. Under warranty & AD replaced whole compressor. Sound was minimized but still on and off whirring noise exactly like the video. Let me know if you guys manage to solve this annoying issue
