This little connector is falling apart and leaking air, so I need to get a new one. The problem is, I dont actually know what the part is called... Does anyone have a part number, or at least know what the part is called? Thanks.

 

that is a check valve and it appears to be the one for the evap system. it stops air from flowing, and only allows its to flow one way. if your an electronics guy, think diode for air

 

Thanks for the info bro. I brought a picture to audi, and they were able to get me another. Its already in and my B5 is back running good...for now >.<

 

It's a love/hate relationship; that's why I bought a Chevy. But I still have dreams about an Inferno Red B7 A4...

 

Lol. I need to get a beater. My b5 is my daily, and I drive alottt a day. Need to stop adding to te 157,XXX that's on it now >.<

 

Lol Pat, you were tired of love/hate so you left and went to all hate.
