Strange noise from MMU2s

Dear all, 

I have this issue when I switch ON my prusa i3 Mk3s + MMU2S unit. 

Already tried: 

- Checked assembly guide if I miss something

- Checked all cables

- Checked if any filament is blocked somewhere

- Resetted MMU2 board

Any idea ?

That's just the normal homing of the idler. 

If at first you don't succeed, skydiving is not for you.

Although the original post is almost 2 years old; When I turned on my MMU2S for the first time, I also thought for a moment that something was wrong. But indeed it's the homing of the idler.
