My last issue was the turbo and a P0420, but that was solved by changing the cat... and with much help from Steve in Chicago.
Even with the turbo/cat problem fixed I am getting all the codes above and my performance is suffering.
Back when I was having turbo issues, I performed a boost leak test and I found every leak except for one; it was coming from under the manifold. It was elusive even after spraying starter fluid, pinching lines, etc..
I have already performed Vagcom output tests and everything blows, clicks and whirrs as it should.
I've always had a problem with oil spray underneath the intake manifold and could never trace it to anything.
To make this story short, while I was testing the Kombi valve with the engine off, I blew into the hose leading to the N112. I figured with the engine off, it should be closed, right? Not so. Air was passing through with a gurgling sound. I put paper towel down below it.
The vent-to-atmosphere hose on the N112 was the source of the escape and also was spraying oil over the paper towel. I plugged it with a screw, cleared the codes, then drove to Philly and back.
Surprise - no codes at all, when I'd usually have four or five.
As much as I'd like to leave the screw in the hose, the N112 apparently needs to be replaced. Is there anything else I should check before that?
Can anything go wrong while I have this jerry rigged until I get a new N112?
