Hello there top of the morning to you! First of all I just bought a 2000 Audi TT 1.8T yesterday and didn't realize a few things till i brought her home from the dealer. The key fob needed new batteries so i replaced them thinking it would work to lock and unlock the doors.. That didn't work. So, next I tried locking the doors manually inside the car, pressing the lock button on the center console between the driver seat and passenger seat.. It locked the passenger door but the driver door is still unlocked. I can hear the locking mechanism inside the door when i hit the button but it just wont lock. I can lock the doors the good ol fashioned way using the key inside the door. Any ideas? Thanks!!

 

sounds like something is stripped in the power locking mechanism on the driver's door.

if you press the unlock on your fob twice, does the passenger door unlock?
