• What's the black rubber cap for? Not visible in pic (upper left corner), on the vent hose there's a sensor with 2 wires. What is that?

• Don't mean to be a dick but you could find the answers to your questions by searching. Since I am not a dick (I hope), the manifold nipple is where a hose goes that connects to the turbo pump LDA to increase fuel with increasing boost. The electrical plug on the CCV hose is a small heater to keep the CCV hose from freezing up.

• I think the cap you are talking about is the BOV AKA overboost protector.

• The thing circled is the capped off nipple for the small vac line stuff to go on for an LDA pump.

• That's a great place to connect a boost gauge to.
  I had a Passat Eco and I borrowed the small plastic line going to the EGR and used it to my boost gauge.

• The TD LDA connection.  I did this conversion on mine.  Also put a tee in line for a boost gauge.  AFAIK there's no BOV on the ecodiesel.
