Customer information
Depending on technical equipment
levels, 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 e.g. by vehicle
sensors, 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 may include:
●
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 and is
not stored for longer than an
operational cycle, and only processed
on board the vehicle itself. Often
control units 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.

The following contains general
information about data processing in
the vehicle. You will find additional
information as to which specific data
is uploaded, stored and passed on to
third parties and for what purpose in
your vehicle under the key word Data

characteristics in the relevant
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 where necessary. Staff working

manufacturers) or third parties (e.g.
