System update

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.
