FYI, BMW can never do anything simply...

"With the aid of the 3 sensors, the electronic outside door handle module detects the
status of the outside door handle. Each change in the status of the outside door handle
module triggers the corresponding function.
These functions are:
• Trigger pulse by inserting a hand into the handle recess of the outside door handle;
Capacitive sensor 1
• Unlock request by pulling the outside door handle; Hall sensor
• Lock request by touching the sensitive area on the outside door handle; Capacitive
sensor 2
Sensors
To protect the battery, the outside door handle electronics module switches off the
capacitive sensors for the driver's side after 192 hours when the vehicle is at rest. The
passenger-side capacitive sensors are switched off after 72 hours.
Capacitive Sensor 1
A pulse is generated when a hand is inserted into the handle recess of the outside door
handle.The pulse wakes up the electronic circuitry in the outside door handle.
If the vehicle is in sleep mode, the electronics module will wake up the Comfort Access
and Car Access System 3. This involves the outside door handle electronics module
sending out a wake-up signal via the CAS-bus.
Comfort Access permanently switches on the remote control receiver in order to receive
the data sent from the ID transmitter.
Capacitive Sensor 2
Touching the sensitive area generates a signal from the capacitive sensor 2 until contact
ceases. The electronic module in the outside door handle sends the request via the CAS
bus. The request is to lock the vehicle.
Outside Door Handle Hall Sensor
The Hall sensor is a backup system for capacitive sensor 1. After 192 hours, the outside
door handle electronics in the driver's door enter sleep mode. This period begins when
the vehicle is locked or unlocked. The Hall sensor remains operational for a longer period.
Sleep mode reduces the power consumption of the outside door handle electronics by
switching off the capacitive sensors. By pulling twice on the outside door handle (two Hall
sensor status changes) the vehicle is unlocked.
Note: Both outside door handle electronics modules on the passenger-side
and the rear outside door handle electronics module on the driver's side
switch off after only 72 hours.
Door Locks
The capacitive sensor 1 initiates the vehicle unlocking procedure.
The door locks are equipped with an additional spring to ensure the vehicle can be
opened fast enough. The spring exerts pretension on the central locking drive unit for the
unlocking procedure. The door is already unlocked before an attempt is made to open it
with the outside door handle.
Note: If pulled very fast, however, it may be necessary to pull the outside door
handle a second time in order to open the door."
