Vacuum Line diagram
On my 2011 Z4 35i, replacing boost solenoids and pulled vacuum hose that goes down. It came out easily ... maybe got loose. I am trying to connect it back and couldnt figure out where. It is 9 in this diagram. Does anybody have a clearer diagram ?

9 (there are 2 of them) should go to either front or rear turbo wastegate control.
Im assuming you pulled one off its nipple.. They are a bit of pain to get back... rear is a bit easier... front is harder. Here is a simple n54 vacuumline graph that i found on other forum. Should make it easier.

@KennyP
Thank you ! I have to connect to the one of the front. Very tight space. Could reach it but very difficult to connect. Any suggestions ? |

If you cant get your hand in there then you can unbolt coolant expansion tank and move it a bit to make more room...
You may lose some coolant though if you undo any hoses connected to it. You can later refill and do the coolant bleeding procedure just to be sure... Also remove engine cover if you havent yet. You cant really see the nipple so you have to feel around with your hand and find it. Dont really remember how i did it... it was years ago. And it was troublesome to get it on there. There are also videos on youtube for n54 vacuum lines diy-s that you can check out. heres one for example: but these are all on 3 series or 1 series and they have coolant tank in a different location....
