Testing various things to pass smog test, I discovered that the plastic tube between the air flow sensor and the throttle body was split at the seam, thus being a major vacuum leak. Not hot on spending $80 for new, I sealed the old one up.
Now waiting on a Bosal CAT to bring HC down, but perhaps the NOx is no longer an issue.
I hate seeing old crud in the throttle body, though, and am thinking it might be good to pull it off and clean it up.

LOL. Switch the VIN with a Canadian MK1 Scirocco. They never came with CATS.
You should be able to find those intake boots at a wreckers somewhere.

Wreckers said "no got" when I asked for the friggin rubber boot that connects the plastic tube to the throttle body. Had to buy it from a dealer for $50. Didn't bother asking wreckers for the plastic tube, i glued the seam after the dealer said $80 for a new one.

What a vacuum leak? ;-)
I might have one of those tubes maybe. I would have to do some searching if you "really" need one!
