I have an 01 S4 and my door while firmly shut thinks its still open. Just wondering if anyone knows where the driverside door ajar sensor is. Interior lights will stay on and the alarm will not arm, starting to get a little annoying.Thanks alot guys.

 

Clean the tabs on the connection for the door. might just be dirty and then just see if u can manualy shut it with the door open. that will let u know if the problem is at the connection or if its else where in the wiring.

 

I'll give that a shot, thanks alot.
