Ok, figured out hose #4, however, the connector on the valve/solenoid for the N249 is busted for the turbo connection, so I have to source a new one, I've seen use on Ebay for $15 and new anywhere from $40-110 (vw dealer website), going to hit the junk yard tomorrow (after golf of course) hopefully have some luck there.
Now I still have one hose that I cannot find the connection. coming off that "tree" with the two solenoids under the intake if you look just to the right there is another check valve with a small diameter hose coming off of it, I cannot find where this connects, Looking at my diagram under the hood it looks like it should connect into that "Y" valve somewhere but I can't for the life of me find the connection.
UPDATE: found the connection, I knew it was something simple, that check valve a off the big Y valve has that small connection to it.
Now I just need to get the solenoid replaced and good to go, hopefully.
