vehicle itself. Control units often contain data memories, among other things for customisation of settings via the
vehicle key. They are used to allow information regarding the vehicle status, component load levels, servicing
requirements, technical events and faults to be recorded on a temporary or permanent basis.
The following are stored according to the technical equipment:
—Operating states of system components, e.g. fill levels, tyre pressure, status of the 12-volt 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 during which the vehicle sustained damage.
In special cases, e.g. when the vehicle has detected a malfunction, it may be necessary to store data that were
actually only momentary.
If you make use of services, e.g. repair services or servicing work, the stored operating data can, if necessary, be read
out together with the vehicle identification number and used. The data can be read from the vehicle by staff in 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 out exclusively via the legally prescribed OBD connection(on-board diagnosis) in the vehicle→
.
The read operating data provide a record of technical states of the vehicle or individual components, help diagnose
faults, meet warranty obligations and improve quality. These data, particularly information about component loading,
technical events, incorrect operation and other faults, will be transferred to Volkswagen Commercial Vehicles
together with the vehicle identification number for this purpose where applicable. Furthermore, the manufacturer is
subject to product liability. Volkswagen Commercial Vehicles also uses operating data from vehicle for this, e.g. for
recall campaigns. These data can also be used to check warranty and guarantee claims made by customers.
Event memories in the vehicle can be reset by a service workshop as part of repair or service work or if you request
this.
The event memory should only be read and reset by a correspondingly qualified workshop. Additional information on
the stored data is available from correspondingly qualified workshops.
After a fault has been rectified, the information in the memory pertaining 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 lane
change flash, 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 Commercial Vehicles recommends that you have the reprogramming
entered into the digital service schedule by a suitably qualified workshop.
Correspondingly qualified workshops have all the relevant information about this type of reprogramming.
Convenience and Infotainment functions
You can store and modify or reset convenience settings(e.g. customisation) in the vehicle at any time.
Depending on the equipment in the vehicle, this includes, for example:
—Settings for seat and steering wheel positions
—Running gear and air conditioning system settings
—Customised settings such as mirror adjustment or background lighting.
Depending on the equipment selected, you may be able to store your own data in the vehicle's Infotainment
functions.
