2021 Mercedes-Benz AMG GT Communication Module Update

Mercedes-Benz has announced an important Over-the-Air (OTA) service campaign to update the communication module software in the 2021 Mercedes-Benz AMG GT. This update, identified by campaign numbers 23P5497248 and 23P5497249, aims to enhance the vehicle's system stability and improve the availability of Mercedes me services. Owners of an affected 2021 Mercedes-Benz AMG GT will receive this software update automatically without needing to visit a dealership.

Why This Update Matters

Mercedes-Benz AG has determined that the software in the communication module of certain vehicles, including the 2021 Mercedes-Benz AMG GT, does not fully align with the latest series production configuration. This discrepancy can potentially affect the overall stability of the communication system and the functionality of connected services. The software update provides quality-enhancing optimizations designed to resolve these issues, ensuring a more reliable and seamless experience for owners.

Understanding the Communication Module

The communication module is a critical component in modern Mercedes-Benz vehicles, responsible for enabling various connected features and services. This includes navigation updates, emergency call functions, remote services via the Mercedes me app, and other telematics capabilities. A properly functioning communication module is essential for the full suite of Mercedes me services to operate as intended, providing convenience and safety features to the driver of the 2021 Mercedes-Benz AMG GT.

How the Update is Delivered

This service campaign is conducted entirely Over-the-Air (OTA). This means the necessary software updates are automatically downloaded and installed in your 2021 Mercedes-Benz AMG GT without any intervention required from the owner or a dealership. The process is designed to be convenient and free of charge, eliminating the need for a workshop visit. The download and installation typically take approximately 15 minutes and can occur in the background, allowing the vehicle to be used without restrictions during this time. The new software will become active once the vehicle has been switched off and restarted.
