Name this hose! (n55 135i engine bay pics)

e36bmer · 12-09-2014, 12:08 PM

My gf got a pretty modded 2011 135i. I took off the intake and engine cover on it to replace the battery cable that had corroded and fallen apart (which took me an annoyingly long time to diagnose why her car wouldn't start) and there's a loose hose, what appears to be a vacuum hose. It comes from the driver's side firewall, around the strut bump and towards the engine, it was just laying on top of the engine. I've uploaded a couple pictures to show what i'm talking about.

What is this for and where do I plug it into? I couldn't see anything around it to plug into.

I'm hoping it's something rather important, because this has turbo-back exhaust, intake, intercooler, oil cooler and JB4 and it doesn't feel that fast. Actually, some days It'll be really quick, and most days it's a little disappointing. I spanked her in my Cayenne Turbo and she was pretty sad.

Any help?

Goes to valve cover near the wastegate actuator. There will be two ports.both will have something in it. Think the one will be the waste gate actuator and then the other will be that line.

That pipes into another vacuum line that attaches to the valve cover. Feeds the exhaust flap. Hopefully the valve cover end is capped, otherwise you'll have a nice vacuum leak.

Goes to a valve on the side of the valve cover(dpdw valve).
