Volkswagen ID.4: 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.

What are connectivity components?

Control modules for data transmission, interfaces, media and diagnostic connections are connectivity components, through which information and data can be exchanged between the vehicle and external devices or the Internet.

Connectivity components are the key points for cyber security. Connectivity components are also equipped with security mechanisms that minimize the risk of unauthorized access to vehicle systems.

The following connectivity components may not be available in all vehicles:

• Diagnostic connection port
• Control module with installed eSIM card.
• Mobile phone interface
• App-Connect.
• NFC radio technology.
• Bluetooth interface.
• USB port.

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.

Generally, system updates improve the security, stability, and processing speeds of the vehicle systems in vehicles.

WARNING

In spite of the integrated security mechanisms, malware can cause malfunctions in control modules and the vehicle.

Malfunctions may cause serious accidents and fatal injuries.

• If the vehicle works or reacts differently to normal, reduce your speed in a controlled manner.
• Contact qualified professionals for assistance. Volkswagen recommends contacting an authorized Volkswagen dealer or authorized Volkswagen Service Facility.

Malware can also access data and information that are stored in the control modules, in the Infotainment system, on connected data carriers, and in paired cell phones.

Minimizing risks

You can actively help to reduce the risk of unauthorized access to vehicle systems and functions by following these guidelines:

• Only use data carriers, Bluetooth devices and cell phones in the vehicle that do not contain any manipulated data or malware.
• Install the system updates provided by Volkswagen immediately.
• Only have the vehicle repaired and serviced by suitably qualified professionals. Volkswagen recommends contacting an authorized Volkswagen dealer or authorized Volkswagen Service Facility.

WARNING

Computers, data carriers and cell phones that are connected to the Internet or are used in public or private networks can be infected by viruses through manipulated data and by malware. This may cause a complete loss of data or damage to computers, data carriers or cell phones.

• Protect computers, data carriers and cell phones with a suitable antivirus program and by taking generally recognized precautions.
• Regularly update the antivirus program using the supplied system updates or upgrades provided by the vendor.

Introduction

The system update is a preventative measure, for example, to protect from malware and to optimize functionality.

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

Depending on the vehicle and country, this can be performed in two ways:

• System update by a suitably qualified authorized Volkswagen dealer or authorized Volkswagen Service Facility.
• System update by Volkswagen via an Over-the-Air Update.

How do I recognize an upcoming system update?

When switched on, the Infotainment system displays an upcoming system update.

If multiple system updates are available for the vehicle at a given time, one system update must be successfully completed before the next system update can be carried out.

WARNING

In very occasional circumstances, there is the possibility that a control module may no longer work properly after a system update. Malfunctions in a control module and the vehicle can cause serious accidents and fatal injuries.

• If the vehicle works or reacts differently to normal while driving, reduce your speed in a controlled manner.
• Contact qualified professionals for assistance. Volkswagen recommends contacting an authorized Volkswagen dealer or authorized Volkswagen Service Facility.

WARNING

If the digital instrument cluster malfunctions after a system update, no instruments, warning lights, symbols or messages can be displayed. Driving with a malfunctioning instrument cluster can lead to serious accidents and fatal injuries.

• Do not use the vehicle. Contact Volkswagen Customer Care.

A measure (e.g. engine tuning) to increase performance or efficiency that has not been undertaken by Volkswagen may be undone when you update the system.

Depending on the vehicle equipment, "release notes" that describe the changes to the vehicle status may be displayed once before or after a system update. The release notes cannot be viewed again after this.

Prerequisites for a system update

The following prerequisites must be met so that the system update download can take place and you can install the software.

✓ The "system update" function is available in your country.

✓ Your current privacy settings allow sending and receiving of data and information.

✓ You have assigned the vehicle to your active Volkswagen user account.

✓ A primary user has been set up.

✓ The vehicle is in an area with enough mobile reception.

✓ The 12-volt vehicle battery is sufficiently charged.
