Thank You

the locks on a Mercedes are controlled by vacuum, you either have a vacuum leak, or the mechanism in the driver's door has malfunctioned, I am talking about the lock of the drivers door, the actuator may have malfunctioned, check to make sure you have no vacuum leaks, and that your vacuum pump is working, then remove the driver's side door panel, and made sure the actuator is working properly, and there is no bad vacuum lines.
