ok, I took out my acv and it looks like I have to find new places for the BOV line and the pressure/boost sensor line.. where do they go exactly? I think the boost sensor one goes to a metal "line" that was previously capped off but what about the BOV line?

 

T them together. there is a spare nipple under the BAC

 

Dont know why (the length of the lines is rather small anyway), but a friend of mine (dnutzuk in here) told me that the boost sensor should be hooked up by itself (without even the BOV), and the BOV along with a boost gauge line should be connected to the capped nipple under the BAC.

Just mentioning this, so you'll know....

 

The BOV line comes off the manifold, not the ACV. It doesn't need to be changed at all unless it was in the wrong place when you started. It should be on a metal nipple just below the BAC valve and above where the ACV was. You can see it in the pic below. The pressure sensor works fine just tee'd into the BOV line as shown.

 

ok, that sounds great.

just a side note.. maybe this is just a s4/s5 difference, but where those three capped off metal lines are, there's a fourth one on my car that's capped off..

here's a pic, it's where the blue circle is:

 

then leave it capped off...

 

i was just sayin.. wonder what it is?
