hi i have recently rebuilt my 2001 legacy b4 (jap import) during the process i took out the engine to send it away to get done and when i put it back in i know that i dont have the vacuum pipes on right going to the solenoid box, well im guessin i brought it to a subaru garage as the engine management light was coming on at about 5000 rpm and the fault showed up as p1241 yet the computer was not able to tell how to fix this the car runs fine but it is not boosting fully on the second turbo and its doing my head in as i have spent €3000 on the rebuild and id like to be able to get my moneys worth when i drive it.
I still think its down to these vacuum pipes and i have compared in to another b4 same age jap import aswell and his vacuum pipe set up was different than mine.
His one had pipes numbered 10,11 and twelve going into the bottom of his solenoid box and mine dose'nt im really starting to get pissed off and confused hopefully soneone can help i would give my right arm at this stage :neutral:

My suggestion is to forget about what the lines are numbered as and do the following.

-sit down with that diagram and your solenoid box in front of you
there is also some good information in this document http://www.veloce.pwp.blueyonder.co.uk/ ... opprt2.htm (http://www.veloce.pwp.blueyonder.co.uk/Twin%20Turbo%20Operation/ttopprt2.htm)
which will show you a schematic (System chart on page 6) of where the vacuum lines go to with respect to each solenoid/ sensor, etc
then all you need to do is match your lines up with where they need to go to.
pay careful attention to lines that have a restrictor in them, (i know that line #2 in the above diagram has a restrictor in it on early model TT legacies, such as mine)

My only other suggestion is to do what i am currently doing.
convert it to single turbo operation
