Central locking system, servicing: Notes

Unlike the previous system, which was pneumatically operated, the new generation central locking system operates using electric motors.
The lock actuators in the doors are integrated in the lock and have 2 electric motors.
The lock actuators cannot be replaced separately.
The first electric motor locks the door and the second electric motor locks the interior door mechanism ("Safe" function).
Locked doors can no longer be opened from inside the car.
The lock actuators for the fuel filler flap and rear lid each have one electric motor, and can be replaced separately.
After an accident involving activation of the airbag, the control module for central locking will unlock any active door locks.
The control module for central locking is located inside a protective box in floor cavity beneath driver's seat and carpet, in front of floor pan crossmember.
