N54 Diverting Valve Pressure Sensing Line ::Help::

Hey everyone,

While I was installing my P3 Vent Gauge in my 2007 335i, I broke the fitting that the diverting valve sensing line taps into. I was trying to pull it off the old fittings (at the diverting valves) but inadvertently broke the fitting on the other end (opposite end of the diverting valves).

Anyways, I have new fittings and I'm nearly ready to go, I just can't find where the other end of the sensing line is supposed to go. I've included a picture to help me explain things better.

In a nutshell:
Where does this (marked in red) plug into?!




Thank you in advance for your help!

You're going to need a new intake manifold or going to have to tap and drill in a new insert.

Unfortunately you are not the first person to do this.

So it connects to the underside of the intake manifold?

Oh boy...

Here's the finished product. I ended up drilling and tapping it out and installing a 1/4" to barb tubing fitting. It's rock solid and, in my opinion, better than it came from the factory. I added some epoxy for good measure... it kind of dribbled though, haha.
