Technical Background

Audi Technical Service Bulletin (TSB) 2079981/1 identifies software issues as the root cause for the restricted infotainment and connectivity functions. Modern vehicle infotainment systems are complex, relying heavily on sophisticated software to manage various features, from navigation and media playback to internet connectivity and vehicle diagnostics. When this software encounters bugs or inefficiencies, it can lead to a range of operational problems, impacting the user experience and the vehicle's integrated services.

Audi states that a production solution for these software issues will be gradually implemented in 2026, depending on the specific model. For current 2025 models, a service update is available to address the existing software deficiencies.
