..I have a 2002 Audi TT and the passenger side door keeps saying DOOR AJAR...But when I hit a Bump it will go OUT..and then back on...So..?? The question is..?? Is the DOOR AJAR sensor.?? is that a Micro switch or does it work off of some kind of GROUND..?? Cause If i mess with the Latch in the door it will go out...I tried lubing it up and it still dont help...

 

There should be a switch in the door jam somewhere.
