Mysterious separated vacuum hose...PICS...2001 A4 1.8T
So i've been trying to diagnose some engine problems, particularly one with the code P0411 (secondary air injection system, incorrect flow), when I came across this broken off vacuum hose near the back, top of the engine. Check out the pics and let me know where u think it goes cuz I can't find where.

I'm thinking it might connect to the check valve just above it. I believe that one is a 3-way and the third arm has broken off into the loose hose. Correct me if I'm wrong
