Fully electric door lock
Another new feature of the A8 is the actuation of the door locks. An "e-lock" is used in which an opening signal is transmit-
ted electrically from the door inner handle or door outer handle to the door control module via a microswitch. The door
control module in turn controls an electric motor which releases the rotary latch, opening the lock. The microswitch for the
door outer handle is located in the support arm. It moves after a few millimeters of pressure on the door handle. The door
control module triggers the electric motor in the "e-lock" and the door can be unlocked with very little effort.

Emergency release mechanism
To open the doors in the event of an electrical malfunction,
two Bowden cables are used; one from the interior door
handle and one from the exterior door handle.
To open the door from the interior, the interior door handle
must be pulled far beyond the normal "e-lock" opening
angle.
Opening the door with the exterior door handle can only be
done after the lock cylinder or interior door handle have
been actuated. The exterior door handle can then be pulled
further than the normal actuation angle and with more
force.
