599 hgte squeaking

Hi, I have a weird problem. When engine warms up, after few accelerations car starts squeaking (like a superchargered engine) It isn't loud but iritating. When i accelerate noise is loudler also when i shift the gear down. I was in ferrari service in Warsaw, unfortunately they did nothing about it, after 60 kilometers test drive and excpept changing the air filter It's not transmission because on N gear is squeaking too.
Do you know what it might be?
Here is short video with this problem, (i recommend headphones)
