I have the 02 A6 with the 2.7T and i have a oil leak problem coming out of what looks like a quick disconnect with the snap clip is white. Its leaking out of the connection and dripping on to the exhaust side of the turbo. I also have another leak coming out of the drivers side turbo oil pressure bung. I may just check the torque on the bolt for that one. So does anyone know where the quick disconnect leads to and from? I cant trace what its for, or what system is using that connection. Oil cooler?

 

Hard to figure out what exactly you mean through text any chance you can snap a picture of it?

Looks like its coming in parallel to the turbo inlet. I can also see it has a hose clamp on the other side of the quick disconnect.

 

Found out its the Upper radiator hose.
