My wife's beetle was running very rough and throwing misfire codes, I found a detached tube, which I think is a breather tube. It has ECS on the side, and seems to have melted apart. It seems to slip into a heat shrink like tube. Once I did that, the car runs smoothly (although that tube is collapsing from the vaccum during idle, it is very mushy). Now I need to replace that part. Can anyone help identify this part and where I can purchase it. It is circled below, and is a single tube. Also, how do you remove and replace that one time tube tightener (blocking on the name right now)?
