Peugeot 2008 handsfree microphone failure

I understand you are experiencing issues with the hands-free microphone in your 2022 Peugeot 2008 diesel. To properly diagnose the root cause, could you please elaborate on any recent events that preceded the failure? Have you observed any anomalies in the ambient noise levels transmitted via the microphone prior to the complete loss of functionality? Have you already tried adjusting the volume control during a call to see if it has any effect, and is there any issue with the Bluetooth connectivity?

Thanks for the quick response! I haven't noticed anything out of the ordinary beforehand. Ambient noise seemed normal, and the volume control didn't do anything when I tried fiddling with it. Bluetooth seems okay; it connects to my phone and everything, just no sound through the mic. Any ideas?

Thank you for the additional information. Based on your description, and considering the error code stored in the memory, a defective infotainment system is indeed the most probable cause. I recommend that you arrange for a diagnostic assessment at an authorized Peugeot workshop. Replacing the unit will be necessary in all likelihood.

Took it to the shop, and you were spot on! Infotainment system was the culprit. Cost me 815€ to get it sorted. Thanks for the help!
