Any ideas where this metallic whistling sound is coming from when i hit the gas pedal hard? I believe it is the turbine but id like to hear an opinion. The mini is suffering from a loss of power but at the moment the only codes that i had were P000A-Powertrain and P0420-Powertrain. Any suggestions?

That does sound like a failing turbocharger (not turbine, btw). They tend to sound like a dentist's drill when they are failing, and yours sounds like that. CD
Thanx CD what do you mean "not turbine"? Does that dentists drill as you say could be the shaft touching the mental while spinning? So in other words it should be playing?
You could disconnect the air inlet tube from the turbo, then try to "wiggle" the turbo shaft. There should be absolutely no up / down or side-to-side movement and little-to-none in / out movement. It should also rotate either direction freely. This is not the only way to check a turbo, but it's not difficult either. Handle the air inlet hose gently, I've read that this connection can be easily damaged.
No, I don't have a pic --- my mods don't include the OEM turbo, and I have after-market hoses through-out the air handling system. Follow your hoses from the air filter to the turbo. Disconnect the last hose that attaches to the turbo. If you disconnect the wrong hose, you won't find a shaft to "wiggle". Using your video, it should be the large diameter hose shown at the top, not the one closest to the front of the car, nor the small one going to the coolant tank.
So here is my Engine, would it be the hose im indicating with an arrow the one to dismantle in order to look for the turbo shaft wiggling as you say?
