The central locking does not block the driver's door.
Hello everybody! The driver's door is not locked when the car is locked with the ignition key fob. The alarm is activated, but the door can be freely opened without pressing the key button.
Please tell me what the problem is and how to fix it.: nix:

By your description, I'm assuming that the passenger door locks and unlocks properly which would rule out the key fob and at least the pump portion of the PSE. You can try pulling vacuum on the air line to the driver's door to see if you have a leak. Pull off the VL line on the PSE module and attach a hand pump to do that. If you can't pull a vacuum, you either have a bad line or a bad actuator. If it does hold vacuum, try swapping the VL and VR lines at the PSE module. If the problem switches doors, you might have a bad solenoid in the PSE module.
