Do any of you know what the purpose of that smaller hose is that feeds into the front of the airbox on the 1.8t?

The adapter hose on mine tore and now the smaller hose is disconnected.

Where can I find a new adapter hose?


Also, just ordered new plugs, floormats, and a timing belt kit for my late model AWM. Hope to get her up and running in about 2 weeks.

 

do you have a picture?

 

I think I just figured it out. It's the SAI pump feed.

But mine doens't look like this... there is no L connector w/ adapter end, instead the connection is pipe-to-pipe with a hose and a hoseclamp.

Maybe a it borke and the mechanic implemented a quick fix?

 

Yeah that sort of looks rigged if my memory serves right. If it won't connect to the airbox you could seal the port on the airbox and get a mini breather filter for that hose. It just sucks fresh air from the intake on a cold start for the first minute for emissions.

 

yeah my original guesses were the sai. never seen how it looks before, don't have one.

 

Be thankful for that. SAI is like a grenade with a 7-10 year fuse

 

Sweet, it doesn't sound that critical. If I can't find a new adapter end, or connector hose, I'll just go with a filter head + ziptie.

Is this something that only late model B5's have?

 

Yes, I believe only 99.5+ have a SAI. The rest of us have an EGR valve, which is an equally large pain in the ***

 

i dont have either of those. im special... Got the car like that too. And the p.o. Was 40 and bought it off a lease so i doubt he deleted anything. Or even knew how..

But i think 99.5 should have an sai cause nic (somebody5788) has one in his 2.8
