This issue, affecting the MIB3 infotainment system, can significantly degrade call quality and communication clarity. This bulletin outlines the symptoms, the underlying technical cause, and the recommended software-based solution to eliminate the 2022 Audi MIB3 hands-free noise.

Symptoms of Hands-Free Noise

Owners experiencing this issue typically report that during a hands-free phone call, the person on the other end of the line hears a distinct "cyclical noise interference on other end of line." This interference is often accompanied by the customer's voice sounding "very faint" to the call recipient. Conversely, the voice of the person speaking to the Audi driver may be described as sounding "distorted or robotic." These communication problems occur irrespective of the engine speed, indicating a consistent system fault rather than an engine-related vibration or electrical interference.

Technical Background: The Software Culprit

Audi has identified the root cause of this hands-free communication problem as a software issue within the MIB3 infotainment system. Specifically, the fault lies within the "005F - Information electronics 1" control unit, which is responsible for managing various communication and infotainment functions, including hands-free calling. The software version 36* is noted in relation to this issue. This software anomaly leads to the unwanted 2022 Audi MIB3 hands-free noise, impacting the clarity and quality of calls.
