Customer information
Depending on technical equipment
level, the data stored is as follows:
Operating data in the vehicle
Control units process data for
operation of the vehicle.
Vehicle data recording
and privacy
Event data recorders
Electronic control units are installed in
your vehicle. Control units process
data which is received by vehicle
sensors, for example, or which they
generate themselves or exchange
amongst themselves. Some control
units are necessary for the safe
functioning of your vehicle, others
assist you while you drive (driver
assistance systems), while others
provide comfort or infotainment
functions.

system component operating
states (e.g. fill level, tyre
pressure, battery status)
faults and defects in important
system components (e.g. lights,
brakes)
system reactions in special
driving situations (e.g. triggering
of an airbag, actuation of the
stability control systems)
This data includes, e.g.:
●
vehicle status information (e.g.
speed, movement delay, lateral
acceleration, wheel rotation rate,
"seat belts fastened" display)
●
ambient conditions (e.g.
temperature, rain sensor,
distance sensor)
As a rule such data is transient, not
stored for longer than an operational
cycle, and only processed on board
the vehicle itself. Control units often
include data storage (including the
vehicle key). This is used to allow
information to be documented
temporarily or permanently on vehicle
condition, component stress,
maintenance requirements and
technical events and errors.

information about data processing in

Protection closely linked to the
In special cases (e.g. if the vehicle
has detected a malfunction), it may be
necessary to save data that would
otherwise just be volatile.
When you use services (e.g. repairs,
maintenance), the operating data
saved can be read together with the
vehicle identification number and
used when necessary. Staff working
