Can someone help me identify the hose / vacuum line in the attached pictures? I have the line patched with tape at the moment. It affects idle and makes the car run very rough if leaking. The line is basically crumbled.
The hose with AEM connects to the broken line in the subsequent picture.
The line with tape is broken. I need assistance to identify this part.
Offhand I don't know what that line is - but it might be a vacuum line to the power brakes (or not..) What might be helpful in getting an intelligent answer is letting us know what year/engine your Cayenne is.
