Why can't the door be opened from the outside after unlocking an Audi A6?

[KinsleyFitz]

Audi A6 cannot open the door from the outside after unlocking for the following reasons: 1. Rear door cannot be opened: If the rear door cannot be opened, it may be due to the child safety lock being activated. It is recommended to turn off the child safety lock. If the issue persists, it could be caused by a detached linkage or a damaged lock mechanism. 2. Component aging: The motor inside the door lock assembly may have aged, leading to insufficient power, which prevents the unlocking motor's linkage lock pin from popping out. As a result, the exterior door handle may not engage properly. The solution is to replace the original imported door lock motor, replace the central door lock unit assembly/lock block, or for a simpler fix, directly replace the motor.
