939003733 - P010 CENTRAL LOCKING NOT WORKING

When the central locking is operated via the driver''s door using the mechanical insert and/or from the inside, via the locking/unlocking buttons, the central locking system does not work. The deterrent LED in the driver''s door panel signals that the locking has taken place. The locking will only be carried out if all the doors are properly shut. The inhibition of the locking is signalled by an LED in the door panel flashing quickly for 3 seconds.
