As a rule, these data are volatile and are not stored beyond the operating time and are only
processed in the vehicle itself. Control units often contain data memory, e.g. for the personalisation
of settings via the vehicle key. These are used to document information regarding the vehicle status,
component load levels, maintenance requirements, technical events and faults on a temporary or
permanent basis.
Depending on the technical equipment, the following data is stored:
—Operating states of system components, e.g. filling levels, tyre pressure, status of the vehicle
battery.
—Faults or malfunctions in important system components, e.g. lights, brakes.
—System reactions to specific driving situations, e.g. triggering of an airbag, intervention of the
stability control systems.
—Information on events which damaged the vehicle.
In special cases, e.g. when the vehicle has detected a malfunction, it may be necessary to store data
that would normally only be volatile.
If you make use of services, e.g. repairs or maintenance work, the stored operating data can, if
necessary, be read and used together with the vehicle identification number. The data can be read
from the vehicle by employees of the service network, e.g. workshops, or third parties, e.g.
breakdown services. The same applies to warranty cases and quality assurance measures.
The data is read via the legally prescribed OBD connection (”on-board diagnosis”) in the vehicle →
. The operating data that is read documents the technical status of the vehicle or individual
components thereof and provides support with fault diagnosis, compliance with warranty
obligations and quality improvement. These data, in particular information on component load-
levels, technical events, operating errors and other faults, are transmitted to Volkswagen together
with the vehicle identification number if necessary. Furthermore, the manufacturer is liable for the
product. Here too, Volkswagen uses operating data from vehicles for product recalls, for example.
These data can also be used to check the customer's warranty and guarantee claims.
Fault memories in the vehicle can be reset by an authorised workshop or at your request as part of
repair or service work.
The event memory should only be read and reset by a qualified workshop. Additional information on
the stored data is available from qualified workshops.
After a fault has been rectified, the information in the memory relating to the fault is deleted. Other
memory content is overwritten on an ongoing basis.
Reprogramming control units
All data for the control of components are stored in the control units. Some convenience functions,
such as convenience turn signal, single door unlocking and displays, can be reprogrammed using
special workshop equipment. If the convenience functions are reprogrammed, the specifications and
descriptions in this owner's manual will no longer match the original functions. Volkswagen
recommends having any reprogramming entered into the digital service schedule by a Volkswagen
dealership or qualified workshop.
Information about possible reprogramming can be obtained from the Volkswagen dealership.
Convenience and Infotainment functions
You can store convenience settings (personalisation) in the vehicle and change or reset them at any
time.
Depending on the equipment in the vehicle, this includes, for example:
—Settings of the seat and steering wheel positions.
—Running gear and air conditioning settings.
—Personalised settings such as mirror adjustment or background lighting.
