Ok bought my jetta last month. It has 115k on the odo but got it for a steal. But it had a check engine light. vagcom p2112. Found the flap motor unplugged. Hhhmm..... Plugged it in light goes out but engine stumbles and stalls. Start it back up idles for a few and dies. Unplug it again runs fine. Take flap motor off intake take it apart. Gears all good travels freely. Cleaned all the goo out of it and notice when it springs shut the plate sticks in the bore. Tight fit but shouldnt stick so I take plate out and scotchbright the bevel a bit. No stick now. Put it back on car. in run position valve is 1/2 open. turn key to off valve snaps shut. After 8 seconds valve opens all the way. Put intercooler snorkel on start it up engine dies with valve 1/2 open. *** ? What controls this thing ? Stealer wants to clean intake manifold to fix dont understand this. I have read lots about dirty intake and egr but not understanding the corelation. Pehaps egr sending signal to close this thing. Note records indicate egr valve was replaced 4k miles ago. Any one have this problem ?
