We just bought the car and Iv been trying to get it running right, allot of vacuum hoses were messed up and the exhaust is a choppy nightmare (which I will be fixing this week if not tomorrow) so I cant test much right now but I can hopefully finish connecting vacuum hoses and the like. In the mean time Ive been scratching my head around these and I(as well as many others Im sure) suck at reading vacuum and wiring diagrams. some times I get it, other times I feel that they were written by someone who had never seen an engine bay.

so to start.


these dont seem to have anywhere to go? could #2 be part of the split air?


I cant seem to figure out where the one that goes to the top of the mani should go. It isnt or at least doesnt seem to be pictured in the vacuum diagram. while were at it I believe the hose coming from the intercooler is just an intake hose? thats what I seemed to get from searches Iv made.


cant find anything for that line to connect to, nor is there a solenoid for the gray clip to connect to, maybe the go to the same missing part?


this wire...


or this sensor? I thought it might be coolant or oil pressure like the s4 na has near the filter but I have both reading on the instrument cluster.

any help received is greatly appreciated.

 

That one goes to a solinoid that you no longer have on the manifold the air assit valve, for power steering and the like. It has a place that is connected to the upper intake manifold near by, the hose litterally runs up and into the noid and then into the intercooler. Which both ends on yours currently are blocked off.

 

Great thats one out of the way thanks!

 

still working on this, trying to pass emissions this weekend
