weird motor sound Astra J 1.4 turbo - oliv.cleiton - 15:th-Jul-2021

Hi all
I am quite new at this forum, so this is my first poost and I hope not break any rules.
In the last days I noticed my Astra is making some weird noise. It seems there is some broken piece inside and quite often creates this `crack` sound. 
The car is an ASTRA J 1.4 turbo 140cv with 67.000km
I want able to attach the video, but I share a google drive link where you can watch and hear the noise.

Hope you guys can help me.
Tks!

Hi guys. I share another link with a video in which the air conditioning is On and there is no noise, then i turn it off and the noise starts.

It's only a guess but as it seems linked to a/c maybe compressor clutch bearing, when freewheeling makes noise when clutch engaged and everything is solid all good.
