Overfilled Expansion Tank

I am reading about the bleeder screw for the cooling system. However, this seems like for getting air out of the system.

I accidently added too much water to my expansion tank because the plunger was stuck at the bottom. When I dislodged it, it shot full extension.

What should I do? Is there a screw release? Or should I try to syphon?

I found an old CN90 post suggesting a turkey baster extraction. Going to give this a try.

That will work.

and yes the bleeder screw is for Bleeding air out of the cooliing system.

Um, I would just undo the blue drain plug one turn with a #3 philips, and drain until the level went down?

Edit - My apologies, I missed this was for an E39, not an E46.
