*DIY* - B5 1.8T Vacuum/Check Valve/SAI/PCV - Delete & Simplification

[walky_talky20]

The one nearer the front of the car runs to the Leak Detection Pump. The one nearer the firewall and coolant bottle just runs to the vacuum reservoir in the fender.

Check the last photo in post #5. The one that is circled corresponds to item #12 on the factory vac diagram (to vac reservoir). The other line below that corresponds to item #16 (to LDP).

Since i am too AEB, do you have any pictures or instructions? Thanks tons and much appreciated.

AEB here and I deleted the pcv and all vacuum and check valves, except for the brake booster, and lines needed for boost gauge and turbo. I will say, that since I deleted all the vac lines, I never hooked my vac reservoir back up, and my cruise control doesnt work. Ill be hooking it back up soon and seeing if that fixes it. I also done an occ setup, with the use of 034's block breather adapter.

Resurrection bump! For anyone who has removed all of these systems. Have you had any drivability issues? My wifes avant needs a major refresh or to just remove everything. The suction pump and check valves on the EVAP system are the worst of the systems.

Thanks!

I just did of this what I could, the only real thing to remove was the purge valve and the vac. lines going to it from the TIP and the lines going behind the block and under the coolant reservoir. Removed all the old shroud back to behind the block and un-tangled all this mess. Evap deleted (I left the line going under the driver side fender with a check valve going to the bottom of the IM). I will leave the evap purge valve electronically plugged in and the hard line is under the fender. I put all the wires for the purge valve, N75, and ICM behind the second firewall. I've still got cleaning up to do here. Hopefully no CEL once all is said and done.
