Your video is a bit short and hard to hear, but if I was going to take a guess, maybe the turbo actuator. Do you have a scan tool to check for engine codes?

I know video is short and hard to hear, but with max volume it hear 🥴 I'll try to do better. I also think something with the turbo, because the sound is at 2100 and 2800rpm, and I haven't been yet on connected vag.

I have had exactly same thing happen to me but on another car (not a VW) however it turned out to be the timing belt tensioner. I was very lucky as I kept driving the vehicle when at any moment the tensioning mechanism could have crashed costing me few $1000K. Not sure if your car has a belt or a chain but if it's the tensioner it could mean same end result.

I have belt. But why it rattle 2100 and 2800at the exact moment. The sound goes somewhere around the front passenger, what you write may be correct and when I have the right window open it hear it very much. thought it was the catalytic converter or the turbo. anyway, I'll have the belt checked. Thank you 👍🏻👍🏻
