When functional, it spools the turbo up quicker at low rpms. It varies the exaust passage to the turbo. At low rpms it partialy blocks the passage to get the velocity up. At approx 2700 rpm it opens the exaust passage to the turbo fully.
If the twin scroll solenoid for it is not functional, it will spring to the full open position and stay there.
It's in the free, online factory service manual. The Fuel section.
