Hoping someone can help me identify this broken and melted hose. I looked at the PET diagrams and can't figure it out. It comes out of the body right above the transmission and then over to the left side of the car based on another broken piece up there. That piece is then just open and I can't see where it might connect. This is for a 1989 S4. Sorry for the bad pic.

 

Rear AC evaporator drain hose. They get crusty like that.
