In general, this technical information docu-
ments the state of a component, a module, a
system or the surroundings.
These include, for example:
operating conditions of system components,
R
e.g. fluid levels
the vehicle's status messages and those of its
R
individual components, e.g. number of wheel
revolutions/speed, deceleration in move-

position
malfunctions and defects in important system
R
components, e.g. lights, brakes
vehicle reactions and operating conditions in
R
special driving situations, e.g. airbag deploy-
ment, intervention of stability control sys-
tems
ambient conditions, e.g. outside temperature
R
This data is of an exclusively technical nature
and can be used to:
assist in detecting and rectifying faults and
R
defects
analyse vehicle functions, e.g. after an acci-
R
dent
optimise vehicle functions
R
The data cannot be used to trace the vehicle's
movements.
When your vehicle is serviced, technical infor-
mation can be read from the event data memory
and fault data memory.
Services include, for example:
repair services
R
service processes
R
warranty events
R
quality assurance

The vehicle is read out by employees of the ser-
vice network (including the manufacturer) using
special diagnostic testers. You can obtain more
information there, if required.
After a fault has been rectified, the information
is deleted from the fault memory or is continu-
ally overwritten.
When operating the vehicle, situations are con-
ceivable in which this technical data, in connec-

tion with other information (if necessary, after
consultation with an authorised expert), could
be traced to a person.
Examples include:
accident reports
R
damage to the vehicle
R
witness statements
R
Further additional functions that have been con-
tractually agreed upon with the customer allow
certain vehicle data to be conveyed by the vehi-
cle as well. The additional functions include, for
