not sure where the small hose goes, and another question i had was can i just put a filter on the end of the air pump? thanks

 

yes the large tube is just a fresh air source for the airpump and i cant quite tell where that little one is coming from

 

pretty sure the first one goes in the stock TID

 

Yea that does go to the stock TID. I can vouch for it.

 

so do i need to block that line off? or what?

 

I'm going to say that the small one is for the twin scroll system... isn't that the check valve? and I thought that went on to the lower nipple on the front of the UIM. But I could be completely wrong. I've never had a working s4 turbo before.

 

bump. tryin to find out the samething.

 

What part of goes into the back of the turbo inlet duct is not understood? Talking the small line with the checkvalve that is part of the purge system.

 

can i leave that hose with the nipple open or do i have to plug it in the TID??

 

can this be the problem for my jerking in 1st gear around 2krpm. help someone all i did was put a TID on and now its starts jerkingdo i need to plug the hose in the TID????

 

An open hole in the turbo inlet duct sucks.

About the fellow who has no stock turbo inlet duct.........just pull the check valve off and let it dangle in mid air. Thats where at certain times the crankcase fumes go to.
