There should be nothing on the LIM. The only thing it could be is as posted split air pipe from the ACV.

Its an s5 engine with an s4 intake and by back side i meant the side facing the fire wall. i dont have any extra hoses to hook up to it so i dont know if the previous owner just took it off and kept it that way

Jeez this thread is frustrating. I don’t have an NA so I'm not sure what it is but I can tell you that it is on the LIM (you can see it clearly in several FSM pictures) and it is not a heater hose (their connections are nowhere near the LIM). My guess would be brake booster, but surely someone with an NA can just go out to their car and look? How hard is that?

I assume the photo is showing the pipe from the ACV.

Its not the brake booster line.
Its not the coolant line.
We know its an S4 N/A... look at the EGR valve located on the center iron.
Look at the ACV valve... Hose going into the ACV from the air pump, but no hose coming out of the ACV.
On the S4 turbo models, the air also travels through the LIM, but there is no nipple. In its place is a flange mounted pipe, mounted on the back edge of the runners. The EGR valve on the turbos is located where this pipe is shown.
Answer: Its the split air pipe which connects to the catalytic convertor on an S4 N/A only.

There are 3 different S4 ACV's.
The N/A manual trans, the N/A auto trans, and the turbo.
To go even further, the turbo ACV's have a different bolt pattern than the N/A ones.
They are completely different units.
You are right, though, that this is a pipe from the ACV... its just not connected to the ACV. Its connected to the LIM.

Im asuming that this was responsible for supplying the actuators with the back pressure needed. But i dont have the auxilary system set up so is this just gonna create a vacuum leak if it is not pluged up
Or i could be completly wrong about what its for.... i just need to know whether or not its gonna create problems with starting up the engine

It WILL NOT create problems when starting up the car. I ran without it for a long while. It DOES create a vac leak, but it's only about 90-125 RPM worth of a vac leak.
Go to Advance Auto or NAPA, and look for a normally *very* small display of "HELP" brand products. Get the biggest cap they sell, called the "Bypass Cap" --- It is a perfect fit. Little bit of RTV on the nipple, cap on, and a clamp.
