Unhappy Where does this hose go???
It's just setting there, feels like it's connected to one of those metal lines underneath the intake manifold. i don't see anywhere to plug it into.

Almost looks like the FPR hose, but I cant be sure. The pics are a little fuzzy. Although if memory serves, the FPR for the S5s is in the back, so that blows my theory out of the water.

This is just a guess, but I can see you did the tb mod. There was a thingy on there (forget what it is/does) that has a vac line running to it that you remove during the mod.

It almost looks like the vacuum spider line that connects to the TB and then splits via the spider to the oil injectors. Just a guess though.

you might be able to just get away with putting a bolt in it if there is no longer anything for you to connect it to.

I have only worked on S4's, but could it go to the fuel rail, meaning the little fuel pressure reuglator on the end of the fuel rail.
