NOTES
Please refer to the vehicle manufacturer's web‐
site for the applicable data privacy policy. This
data privacy policy contains information about
the right to have data deleted or corrected. The
vehicle manufacturer's website also provides its
contact details and those of its data protection
officer.
The data is only processed within the vehicle it‐
self and is usually transient. The data is not
saved after the vehicle is switched off.
Electronic parts, for example control devices and
vehicle keys, contain components for storing
technical information. Information about the vehi‐
cle's condition, component use and wear, main‐
tenance requirements, events or errors can be
stored temporarily or permanently.
The vehicle owner can have the data saved in
the vehicle read out by a Service Partner of the
manufacturer or another qualified Service Partner
or a specialist workshop, on payment of a fee
where applicable.
This information generally documents the condi‐
tion of a component, a module, a system or its
environment, for example:
The legally required on-board diagnosis OBD
socket in the vehicle is used to read out the vehi‐
cle data.
▷ Operating states of system components,
for example fill levels, tyre inflation pressure,
battery status.
▷ Malfunctions and faults of important system
components, for example lights and brakes.
Legal requirements regarding
data disclosure
According to current law, the vehicle manufac‐
turer is obliged to provide the authorities with any
data it has stored. Data is provided to the extent
required and on a case-by-case basis, for exam‐
ple to investigate a criminal offence.
▷ Responses of the vehicle to particular driving
situations, for example triggering of an airbag,
activation of the drive 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, and helps the ve‐
hicle manufacturer to optimise vehicle functions.
The current law also gives state bodies authori‐
sation to read out data from the vehicle them‐
selves for individual cases. This could include
reading out data from the airbag control device
to shed light on the circumstances of an acci‐
dent, for example.
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 error
memories in response to specific circumstances.
Operating data in the vehicle
Control devices process data to operate the ve‐
hicle.
When service work is being carried out, for ex‐
ample repairs, service operations, warranty work
and quality assurance measures, this technical
information can be read out from the vehicle to‐
gether with the vehicle identification number.
This data includes, for example:
▷ Status messages relating to the vehicle and
its individual components, for example wheel
rotation speed, wheel speed, deceleration,
lateral acceleration, fastened seat belt indica‐
tor.
A Service Partner of the manufacturer or another
qualified Service Partner or a specialist workshop
can read out the information. The data is read
out via the on-board diagnostics (OBD) socket,
which the vehicle is required to have by law.
▷ Ambient conditions, for example temperature,
rain sensor signals.
The data is collected, processed and used by the
relevant organisations in the service network.
The data logs the technical conditions of the ve‐
