2001 Audi A4 turbo need help
 

I need help identifying a hose on my car. I took it to the part store, and the guy had me order some part that looked nothing like it. I tried to upload photos, but it obviously didn't upload. It's with a coolant leak. I know where the leak is. Don't know what it's called to order correct part. Please someone help.

If my second pic turns out it's the bottom hose under the big one. I need to know the name.

I've figured it out on my own. Thanks for all the tips.
