I can't hear what you are talking about maybe I have a bad ear or a bad speaker, which part of the video is the loudest?

Sounds like the sound is coming from a rotating part? Could it be the rotors?

Ah I hear it, sounds like a wastegate although still pretty far from it but then it does sound like brake pads grinding rotors like another forum member mentioned. Please keep in mind that brake pads are always touching on rotors even if you are not braking so it doesn't have to move into position when you apply the brakes improving safety. It is just that, when you don't apply brakes, it doesn't apply any pressure.

Does the sound get louder when you cold start and drive in the morning and/or when outside temperatures are low?

no the sound happens when i’m on the gas a and the turbo gets to max on the dial so you think that gargling noise is the brake pads?

Worth checking, make sure it isn't a stuck piston or anything.
