Berlingo hands free microphone failure

I also drive a Berlingo and experienced something similar. The sound quality during calls became abysmal before failing completely. Does the error message mention anything specific about the microphone circuit?

The error message is generic, indicating a fault within the hands-free system, without specifying the precise source or 'microphone circuit'. Were you able to resolve the issue yourself, or did you require professional assistance?

A generic error is never helpful! I ended up having to take mine to a workshop. From memory, the repair wasn't cheap. Given your mileage and the error code, it really does sound like the infotainment system. You might be looking at a similar expense to what I faced. Sorry to be the bearer of potentially bad news!

I appreciate your honest assessment. I took it to a local workshop, and indeed, the infotainment system was deemed defective. The repair cost amounted to 815€, as you predicted. Thank you again for your help.
