Hi Audi Forums!!! I have a Audi issue and Iam unaware as to what to do with limited funds. Mechanic said my Engine has zero (0) compression in 2 cylinders on passenger side (right bank) of car. Also, Intake camshaft sprocket bolt is loose and wont tighten up. What can I do to check what the actual problem is? Ive heard of "leak down test" , Ive done some research on how to perform this, but I don't have a compression tester kit.

Also, Mechanic broke this small tube/pipe (Picture) off of Air Intake Hose. what is it called, and can I replace just the small tube/pipe, as the mechanics are really professional and don't know anything....

Second picture of cover.....what is it called, were does it go on the vehicle, and will it work being broke the way it is, right at the seal. Thanks every one!!!

I figured out what these are and were they go, First air intake hose, I was able to superglue it together and it works fine. Second piece is a cover for the fuse box located under the hood on driver side up towards windshield.
