Data transfer
Cyber security
Control units with integrated eSIM cards, interfaces, and also media and diagnostic connections are
connectivity components via which information and data can be exchanged between the vehicle and
external devices or the internet → . The connectivity components include the following in
particular:
—Diagnostic port.
—Control units with integrated eSIM card.
—Volkswagen Car-Net control unit.
—Mobile phone interface.
—Media Control.
—App-Connect.
—Wi-Fi hotspot.
—Bluetooth connection.
—USB port.
—AUX-IN socket.
—SD card slot.
—SIM card slot.
Connectivity components are the key elements for cyber security. In addition to other control units,
connectivity components in particular are equipped with security mechanisms that minimise the risk
of unauthorised access to vehicle systems.
The software and security mechanisms in the vehicle are subject to ongoing development. Like with
computers or the operating systems of mobile devices, the software and security mechanisms in the
vehicle may also be updated at irregular intervals.
Software updates improve the security, stability and running speeds of the vehicle systems in
vehicles that have already been produced.
You too can actively reduce the risk of unauthorised access to vehicle systems and functions:
—Use only data media, Bluetooth devices and mobile devices in the vehicle than do not contain
manipulated data or malware.
—Have the vehicle serviced, repaired and maintained only by a qualified workshop. Volkswagen
recommends using a Volkswagen dealership for this purpose.
WARNING
Computers, data media and mobile devices that are connected to the internet or that are used in
public and private networks may be infected by manipulated data or have malware installed on
them.
●
In addition to the usual precautionary measures to be taken when using the internet, you should
protect your computer, data media and mobile devices with suitable anti-virus software and
regularly update the signatures.
