Data stored in the vehicle
A number of electronic components in your
vehicle contain data memories.
These data memories temporarily or perma-
nently store technical information about:
R the vehicle's operating state
R events
R faults
This technical information generally docu-
ments the condition of a component, a mod-
ule, a system or an environment.
These are, for example:
R operating conditions of system compo-
nents. This includes, e.g. fluid levels.
R status messages from the vehicle and from
individual vehicle components. This
includes, e.g. number of wheel revolu-
tions/speed, deceleration, lateral acceler-
ation.
R malfunctions and faults in important sys-
tem components. This includes, e.g. lights,
brakes.
R reactions of the vehicle in special driving
situations. This includes, e.g. deployment
of an airbag, intervention of stability control
systems.
R environmental conditions. This includes,
e.g. the outside temperature.
This data is exclusively technical in nature
and is used to:
R assist in the detection and rectification of
faults and defects
R optimise vehicle functions
The data cannot be used to trace the vehicle's movements over distances travelled.
When your vehicle is serviced, this technical
information can be read out from the event
and fault memory.
Services include:
R repairs
R service processes R
warranty claims
R quality assurance
The information is read out by authorised
employees of the service network (including
manufacturers) using special diagnostic devi-
ces. You can find more information there if
necessary.
After a fault has been rectified, the informa-
tion in the fault memory is deleted or consec- utively overwritten.
In normal vehicle operation, situations may
arise in which this technical data could
become personal in nature in conjunction
with other information and, if necessary, on
consultation of an approval official.
Examples include:
R accident reports
R vehicle damage
R witness testimonies
Further additional features which are con-
tractually agreed with the customer likewise
allow specific vehicle data to be obtained
from the vehicle. Such additional features
include vehicle locating in an emergency, for
example. Copyright information
