r/Corsa

Hi everyone, hoping someone can help because we’re genuinely losing our minds with this.
We have a Vauxhall Corsa Sport and there is a very high-pitched shrill/squealing noise coming from the car (video attached). We’ve already replaced almost everything we thought could be causing it, but the sound is still there.
The noise sounds sharp/shrill, almost like a squeal or whistle. We’re struggling to figure out whether it’s:
brakes/disc shield rubbing
wheel bearing
auxiliary belt/tensioner/pulley
alternator or AC pulley
gearbox/clutch related
air/vacuum leak
We don’t want to keep throwing money at random parts.
Details:
Car: Vauxhall Corsa Sport
Engine/year: 2013
Petrol
Automatic
Parts already replaced: [LIST EVERYTHING]
Noise happens: while driving / idle / accelerating / braking?
Does it change when turning or braking? [YES/NO]
Video attached. Has anyone had this exact noise on a Corsa or know what it sounds like? Any ideas appreciated before we spend even more money 😭

Hi, I have a vauxhall corsa 2019. When I turn the car, the engine shakes alot (as seen in the video) can someone tell me if any corsa owners have experienced this before? If so, what is the issue here?

Hello ,i tried to tune my car and i think i made it worse,what do you guys think? And how can i make it better? I want tinted windows,a new out-exoust and some bigger weels.
