Door opening via the microswitch
The microswitch for opening the door is located in the interior door handle. When the door control module detects the
switch being opened, it triggers the servo motor in the door lock.

In certain situations, for example, when another vehicle is detected within the danger zone by the exit warning system, the
"e-lock" can delay the opening of the door and issue both a visual and tactile warning for a short period of time.
Power latching
The 2019 A8 can be equipped with an optional power latching system. The drive units for this system are different from
previous versions. The Door Closing Aid Motors (V302, V303, V541 and V542) exert a pull via an integrated linear drive
which moves the rotary latch in the door lock to the end position.
Note
Before disconnecting the 12 Volt battery, make sure that one door window is open or that the ignition key is not inside the
vehicle or in the luggage compartment.
