E90 BMW 3 Series with a missing door lock actuator lock rod. I also found the door panel loose on the bottom. Today I am doing some diagnosis on the issue with the driver front door. The door lock actuator gets stuck in double lock. In this video I go over how to remove the door panel and inspect the vapor barrier. I show you how to re-attach the vapor barrier to prevent water leaks and re-install the door panel plus I go over the failure with the door lock actuator.
