Hey there. I got a 97 Passat GLX

Anyone whos familiar with the VR-6 can probablly help me here.

I have this little valve/tube thats actually broken off and I was wondering if anyone could help me indentify it so i could go about replacing it.

I have a picture down below, but if it helps, theres this tube that comes from the motor, goes to some sort of valve and back into a tube that goes back into the air intake pipe right before the throttle body. I put an arrow pointing to the little valve.

If any could help me find out what it is, and maybe where i could get a replacment part, Id be really grateful.
