They call it the "PCV Valve".
Any help would be greatly appreciated.
Thank you.
"the suction pump simply controls the PCV valve, it should not be sucking in the PCV gases unless the valve is busted."

This is why I ask. I just replaced the suction pump because it was completely clogged, and I was getting the oil burning smell in the cab.
I'm pretty sure all my PCV gases are coming through the PCV Suction pump. So I would like to change the "PCV Valve" but I don't know what the official Audi name is for that part. I thought I would try here first before I call Barrier Motors in Bellevue, WA.
Thankyou
