I have a 2000 Jetta TDI.
What is the part that is located on TOP OF THE VALVE COVER....(to the RIGHT of the OIL CAP) ? Is a black diaphragm looking device with a hose coming out of it. The hose on mine is broken and I need to order a new one. Can anyone tell me what this is called? And what the purpose of it? Thank you.
