System update

Introduction to the topic
The factory-fitted central control unit sup-
ports the system update function. This allows
the software of almost all control units to be
updated by Volkswagen AG without the need
to visit a qualified workshop:
If a system update is available for your vehi-
cle, a corresponding message will be dis-
played on the Infotainment system.
System updates are downloaded via the fac-
tory-fitted control unit with eSIM card (OCU)
and are free of charge. Volkswagen pays the
connection costs.
The system update function is only available
in some countries.
WARNING
Control units will be deactivated and will
not function while software installation is
taking place. Driving with deactivated or
malfunctioning control units can cause ac-
cidents and fatal injuries.
·
Carry out software installation in a suita-
ble place where other road users are not
impeded.
·
Never use the vehicle while software in-
stallation is taking place.
WARNING
If the digital instrument cluster does not
function after software installation, no in-
struments, warning lamps, symbols or text
messages can be displayed. Driving with
a digital instrument cluster that is not
working can cause accidents and fatal inju-
ries.

Overview
Please refer to at the start of the chap-
ter on page 196.
Availability of a system update
The switched-on Infotainment system indi-
cates that a system update is available. A sys-
tem update takes place in two phases:
— Down load phase: the download of a sys-
tem update takes place in the background
without any previous notification and is
possible during a car journey.
— Installation phase: software installation is
possible only when the prerequisites for
this are met → page 197, Prerequisites.
Before the installation phase begins, the driv-
er is asked to grant approval.
If several system updates are available for the
vehicle at the same time, one system update
must first be installed successfully before the
next system update can be executed.
In some vehicles, release notes may be
displayed once before or after a sys-
tem update which describe the changes to
the vehicle status. The release notes cannot
be viewed again after this.
