They are both located under the intake manifold. The SAI also needs a vacuum source to the N whatever valve (I am drawing a blank to its designation but it is right next to the N249 valve and it looks the same as the N249). You should be able to hear the N85 rapidly cycling (ticking noise). Start the car and let it idle for a minute or so. Look at the check valve just downstream of the N85 (above the air box) since that one tends to deteriorate from the hydrocarbon vapors. i have not messed with either yet (other then removing SAI tube from the airbox and sticking the breather on it, since i hooked up an intake yesterday, anyway other then that its all stock, why would i be failing those two tests? What should i check for?Evap needs a vacuum supply to the N85. coinsidently i vagged my car yesterday and i'm failing readiness on both Evap and SAI. but i have a question on both of these readiness tests. Also when I go blocks 70, 71, and 77 it says 'TEST OFF'.Īnyone know the factory method of setting the readiness for evap and sec air? In vagcom the 'basic settings' button is not selectable and there is a note that say to refer to factory manual. Close measuring blocks / basic settings and verify in readiness that everything's cool, and you're ready to pass inspection. Once in basic settings, these tests took anywhere from 10 seconds to just under a minute to pass. Once block 70 passed, repeat from step 2 using block 71. Leave car IDLING, and click basic settings.Ĥ. This, i'm assuming, is only pertaining to DBW 1.8t's like me.ģ.

Edit: Note- when you click basic settings while holding the revs, you will immediately drop back to idle, and no matter what you do with the gas pedal, nothing will happen. Readiness for secondary air should now be passed. Raise RPM to 2k and hold it there, and click Basic SettingsĤ Watch the channels, one of them should say Test ON, wait till it says Sys OK, or something like that. I stumbled upon the following method to set the readiness but apparently it doesnt apply to my year 2003 ġ. I have the two remaining readiness codes left to be set before I can have my car inspected again.
