I was in the process of changing out my cam shaft chain tensionor and while making room I attempted to pull off a plastic (pvc type) hose and it cracked and came apart. I am hoping someone can tell me what the name of the part it is I'm needing? 2004 Audi A4 1.8t Quattro.

 

Do a thread search. Can't think of the actual part name but I know this same hose has come up in at least 3 threads in the last few months. Very easy to make your own hose there as I did with some clear vinyl tubing until the replacement part arrived.
