Solenoid won't fix that. ECU is just sensitive about it.

That's the rattle snake I was talking about. Upgrade the factory boost solenoid and it will go away.

Are you overloading the engine basically too high of gear trying to get on it? I do have a mk7 gti as well and that sound is common through either a leak somewhere or a bad turbo. The mk7 gti is notorious for blowing turbos.

I don't think so? it's a DCT, I usually let it choose its own gears during my normal commute. I'll check the silicon reducer at the turbo inlet again, but everything was pretty snug. I think I might just have to upgrade the Solenoid

Sounds like the BOV fluttering. Might need a stiffer spring.

A lot of modern turbo cars will use the bypass valve in conjunction with the wastegate to manage boost pressure entering the engine. I believe it's to keep the turbo spinning at a higher rpm but to not send boost into the engine, which helps with throttle response if you do decide to increase throttle. It goes away when you lean into the throttle more, right? Sounds like this is what's happening in this case, judging by the video.

yes, pretty much. Low/High throttle input you don't hear it, but its that mid throttle input you here it most.
