Mercedes GLE diesel microphone malfunction
Summary of the thread
A 2021 Mercedes GLE diesel is experiencing a hands-free microphone malfunction, rendering telephony inoperable and storing an error. Initial assessments suggest a defect within the infotainment system. Basic troubleshooting steps, such as checking volume controls and speech recognition, were ineffective. A certified technician confirmed the defect, and a system replacement was necessary, as microphone repair was not feasible.

Volume controls have been verified Speech recognition is non-functional across all systems Ambient noise influence has been considered, but ruled out I am trying to ascertain if the entire audio system will need replacement or if a microphone repair is feasible

Right, it's beyond simple fixes then From what you're saying, and the error codes you mentioned, it really does sound like the infotainment system itself Maybe there's a software glitch I'm not aware of, but I'd almost bet it is a hardware problem I’d seriously suggest a workshop visit They can properly diagnose it

I appreciate the feedback Diagnostic assessment by a certified technician confirmed the initial suspicion of a defective infotainment system Microphone repair was deemed unfeasible a system replacement was necessary Final cost 815€

Oh dear, that sounds like a headache I'm no expert, but I wonder, have you tried any of the basic troubleshooting steps Like, did you check the volume control during a call, just in case it somehow got muted Also, does the speech recognition work for other functions besides phone calls Maybe the ambient noise cancellation is acting up
