What is this noise? (video)

Just got a 1.4 Multiair 16V Turbo but there is a scraping noise coming from the engine/turbo every time when giving gas. I attached a video so you can listen to the sound. You can see that when I hold the (wastegate?), the noise disappears. There is also a small turbo lag, the turbo starts a bit late at around 2.5k rpm. Do I need a new turbo or could it be something else? Thank you

Video of the sound: vimeo. com/450136449 (remove the space)

From the video it looks like the head shield rattling against the waste-gate actuator when you “hold the waste-gate” you’re pushing the shield back so it’s not making contact anymore.

Have you removed other parts of the heat shields to be able to access this or were they already missing

wastegate actuator, not much of a problem but if you want it gone, adjust the preload on the wastegate actuator by about 1.5 turns.
