Data in the vehicle
General
A number of electronic control devices are instal‐
led in your vehicle. Electronic control units proc‐
ess data that they receive from vehicle sensors,
generate themselves or exchange with one an‐
other, for example. Many of the control units are
necessary for safe operation of the vehicle, or
provide assistance during a journey, for example
driver assistance systems. There are also control
devices which manage comfort or infotainment
functions.
Data saved in the vehicle can be deleted at any
time. This data is only transmitted to third parties
if expressly requested in the course of using on‐
line services. The transfer depends on the set‐
tings selected for using the services.
Sensor data
Driver assistance systems, for example Active
Cruise Control, Collision Warning or Attentive‐
ness Assistant, process sensor data which is
used to evaluate the vehicle's surroundings or
the driver's behaviour.
These include, for example:
▷
Status messages relating to the vehicle and
its individual components, for example wheel
speed, wheel circumferential velocity, decel‐

eration, lateral acceleration, fastened seat
belts.
▷
Ambient conditions, for example temperature,
rain sensor signals.
The data is processed within the vehicle and is
usually transient. It is only saved for longer than
the operating period if it is required in order to
provide services agreed with the customer.
Electronic components
Electronic components, for example control devi‐
ces and vehicle keys, contain components for
storing technical information. Information about
the vehicle condition, component use and wear,
maintenance requirements, events or faults can
be stored temporarily or permanently.
This information generally documents the condi‐
tion of a component, a module, a system or the
vehicle's surroundings, including:
▷
Operating states of system components, for
example fill levels, tyre inflation pressure, bat‐
tery status.
▷
Malfunctions and faults of important system
components, for example lights and brakes.
▷
Responses of the vehicle to particular driving
situations, for example triggering of an airbag,
activation of the driving stability control sys‐
tems.
▷
Information on vehicle-damaging events.
The data is required so that the control units can
perform their functions. It is also used for detect‐
ing and rectifying malfunctions, as well as to opti‐
mise vehicle functions.
Most of this data is transient and is only pro‐
cessed within the vehicle itself. Only a small pro‐
portion of the data is stored in event or fault
memories in response to specific circumstances.
Personal settings
Convenience functions, such as seat, climate or
light settings, enhance the driving experience.
The personal settings for these functions can be
saved in a profile within the vehicle and retrieved
