Hey guys i'm new to working on audi's and i'm in the process of swapping an engine in a 02 3.0 v6. I am almost completed but i'm stumped on the throttle body coolant lines before i can go any further. There are 4 ports all together, 2 on the bottom are for coolant and 2 on the side i'm not sure what they are for.
Can someone please post a pic of how they should go the car was a little apart before i started and i'm missing one hose. Please help!!

 

2 air 2 coolant (in and out)

 

alright i figured it out. the hose was hiding behind things out of the way i just found it. thanks
