Data transmission

Cyber security

Cyber security describes measures that

reduce the risk of illegal access to

vehicle functions, data and control

modules caused by malware or an

Internet attack. Of all the components

in the vehicle, connectivity components

are most at risk of unauthorized access

or cyber attacks.

Connectivity components comprise control modules for data transmission, interfaces, media and diagnostic connections

through which information and data can be exchanged between the vehicle and mobile devices or the Internet.

Connectivity components are equipped with security mechanisms to minimize the risk of unauthorized access to vehicle

systems.

Connectivity components include in particular:

Diagnostic connection port

Control module with installed eSIM card.

Phone interface

App-Connect.

Wi-Fi® hotspot.

NFC radio technology.

AUX-IN jack.

Bluetooth® interface.

CD/DVD drive.

USB port.

SD card slot.

SIM card slot.

The type and number of connectivity components present in your vehicle depends on the vehicle equipment and the

country.

Software and security mechanisms

Software and security mechanisms available in the vehicle undergo continuous development. Similar to computers or

operating systems on cell phones, software and security mechanisms in the vehicle may also be updated at various times.

System updates improve the security, stability and operating speed of vehicle systems. The system update is a preventative

measure, for example, to protect from malware and to optimize functionality.

A system update is used to update the software of control modules in the vehicle.

Depending on the vehicle and country, there are two ways to update your vehicle:

System update by a suitably qualiﬁed authorized Volkswagen dealer or authorized Volkswagen Service Facility.

Volkswagen recommends contacting an authorized Volkswagen dealer or authorized Volkswagen Service Facility.

System update via an Over-the-Air Update.
