Today I was replacing my vacuum line going from intake manifold to N249 Recirculating Valve (the line people usually take boost readings from).
While in there, I spotted 1/4" hose piece, like a nipple. I guess it is attached to Sec. Air Inj. Solenoid Valve N112, see the picture:

So that unknown piece of tube looks like a vent i.e. cut off vacuum line, 90 deg shape. Is it the it's supposed to be or I am missing something? No CEL, no issues, just curiosity

 

Is it a hose or just a cap?

 

It's a hose

 

I will have to look at mine since they are sitting in the garage somewhere. I thought there were 2 caps on the 2 valves since they really only go to the BPV and the SAI valve.

Is it rubber? Because Audi did not use rubber hoses for the vac lines, this is why I think its just a plug that is bent at the end. Plus if you look at the picture the end of that part is closed.


BTW you can post the actual picture when you post. Just copy the address, click the little picture icon and paste it into the window that pops up.

 

Thank Mike, I will have a second look into this one, it's just not easy to get there (big head)
