Customer information
Information recorded in the
control units
Your vehicle is fitted with electronic control
units. In order to ensure the safe operation of the
vehicle, some control units are needed to control.
Some control units are required for the safe func-
tioning of your vehicle, others support you when
driving (driver assist systems). In addition, the ve-
hicle also provides comfort and infotainment sys-
tem, which are also realized through the elec-
tronic control unit.
Electronic control units are equipped with tem-
porary or long-term storage of data on vehicle
status, component load, maintenance require-
ments, as well as technical content and faults.
Depending on the technical equipment, the fol-
lowing data is stored:
– Operating states of system components, e.g.
filling levels, tyre pressure, status of the vehi-
cle battery.
– Vehicle status information, e.g. speed, deceler-
ation, lateral acceleration, number of wheel
revolutions and display of closed seat belts.
– Faults or malfunctions in important system
components, e.g. lights, brakes.
– Information on events which damaged the ve-
hicle.
– System reactions to specific driving situations,
e.g. triggering of an airbag, intervention of the
stability control systems.
– Ambient conditions, e.g. temperature and rain.
In addition to the application of the control unit
functions themselves, these data are also used by
the company to identify and troubleshoot faults
and optimize vehicle functions. Much of this data
is temporary and applied only inside the vehicle.
Only a small part of the data is kept in the failure
memory and, if necessary, in the vehicle keys.
Read event data recorder
This vehicle is equipped with an event data re-
corder for reading the data stored in the event
memory,
event memory records fault data
→
and data that deviates from the specified value
of the control unit. Additional information on the
212
Owner's manual
stored data is available from suitably qualified
workshops. Volkswagen recommends using a
Volkswagen dealership.
The diagnostic interface is located in the footwell
on the driver side underneath the dash panel.
The event memory should only be read and reset
by a suitably qualified workshop.
After a fault has been rectified, the information
in the event memory relating to the fault is de-
leted. Other memory content is overwritten on
an ongoing basis.
Reprogramming control units
All data for the control of components is stored
in the control units. Convenience functions such
as lane change flashing, individual door opening
and display mode can be reprogrammed with
dedicated devices. If the convenience functions
are reprogrammed, the specifications and de-
scriptions in this owner's manual will no longer
match the original functions. Therefore, Have the
reprogramming entered into the digital service
schedule by a suitably "qualified workshop".
Volkswagen recommends using a Volkswagen
dealership.
Suitably qualified workshops are informed about
this type of reprogramming. Volkswagen recom-
mends using a Volkswagen dealership.
Infotainment system
Depending on the equipment installed, you may
be able to store your own data in the vehicle's In-
fotainment system. The data includes:
– Media files for playback of music, films or pho-
tos in an Infotainment system.
– Address book data for use with a hands-free
system or navigation system.
– Navigation destinations entered.
– Data on the use of online services.
This data can be stored locally in the vehicle or
located on a device that you have connected to
the vehicle, e.g. mobile telephone, USB stick or
MP3 player. If this data is stored in the vehicle,
you can delete it at any time. This data is trans-
mitted to third parties only at your request, in
particular in relation to the use of online services
and in accordance with your personal settings.
