Engine whistling noises

[Sp0_0k]

Noticed some weird whistling\squicking noises mostly destinctive in a cold engine. Should I be concirned? Might be a belt?

Could be an air intake pipe loose or turbo to engine leak but that would usually happen all the time not just when its cold.

Here is a video.
Any suggestions? Is it a belt noise? It got louder lately but mostly when cold start.

To me , i hear noting strange in the movie above...
Cold engine's always sounds strange.

Also note that i am not that familiar with the T6 engine , but i can't hear a wisteling noise...

Normally a slipping belt would be heard on reving the engine and disappear as everything warms up and expands.
on the video sounds like a " cold engine " start up. Cams, cam followers etc: tappets noisier due to increased tolerances due to contraction of cold metal and disappears on warming. Normal.

I can hear it, could be dirt in the groves of the aux belt, could also be a dry bearing in an idler pulley or or the pulley on the belt tensioner. I would spray some silicon on the auz belt and see if it goes away.

Getting louder each time. So nothing to worry about, right?

Definitely worth getting it checked because I believe issues have been reported with aux. belt/tensioners on these new engines?
