View Full Version : N112 Valve replacement help?

11-26-2016, 05:51 PM
Recently, I was replacing my vacuum lines, and.. Well... i discovered the nipple on the N112 Valve that the combi valve line runs to, was cracked off and was literally sitting on the edge of it. I would like to replace the valve to be rid of the P0411 code I have. I found a video to remove the bracket holding the N112 and N249 valves, but the video was only for the transverse motors. i can't find anything for our longitudinal motors regarding the removal. Thank you in advance.

The bracket is a black triangle shaped piece of metal. The bracket is held into the intake manifold by three 10mm bolts. Remove the bolts and the bracket with the attached valves will come off.

I would recommend unscrewing the coolant reservoir, disconnecting the coolant sensor from the coolant reservoir, remove the upper pressure pipe (intercooler to throttle body) and remove the throttle body so you will have plenty of room to work. You could probably get by without removing some of these things, but they are super easy to pull off and would make it a much much easier job.

This is what the bracket looks like.
See the linked thread from absolutegtr who did the master of all vacuum line threads. He goes into great detail on how to simplify the whole vacuum system, but he also notes how to remove the stuff too. Gotta give props to his thread.
