Re:swaping map sensors
put a new cap on it. i haven't ajusted the valves yet...but thas about it..but would that make it bog randomly? it would really help if someone could post a picture of their a6 in an hf. and i could check where the vacuum lines go. thanz

Re:swaping map sensors
the only two you need hooked up are the Fuel pressure regulator (the thing on the end of the fuel rail) and the MAP sensor...---- the rest of it and cap it off, unless of course you live in Cali...
i will look for a pic of mine

Re:swaping map sensors
the map sensor is in the box/bracket of junk on the firewall. if it has a cover, take it off and look around in there - if it's an HF, there should be two canister shaped devices (each with two wires), one boxier device with 3 wires and something my manual is calling a CVC valve - i've never looked at one, so don't ask me. 
the boxy 3 wire device is your map sensor (it should have a label on it - Sensor Assy. MAP) - run it's port to the smaller of the two vac ports on the top of your throttle body.
the cylindrical shaped devices are solonoid valves - one operates the evap. emissions canister, the other was for the EGR system which you no longer have (same goes for the CVC valve). you should be able to look at the vacuum diagram on your hood to figure out which is which.
the bottom port of the evap control solonoid goes to the vac port on the back of the intake manifold. the top port should be covered by a little cylinder shaped filter thing. the remaining side port of the solonoid goes to the top most port on the evap canister. the canister port directly under that should have a red mesh hose going to the large port on the throttle body. the remaining port on the evap canister should have a plain red hose going to a connection on the firewall (to the fuel tank).
