Fault "Mic drivers not calibrated"

G30M · 07-02-2023, 10:58 PM

so both my cars when i scan for fault codes come up with the same thing

"Mic drivers not calibrated" under Receiver Audio Module

why would that be and how do you calibrate these drivers?

B7F500: "Driver's microphone not calibrated" code also in mine in Amplifier (according to BimmerLink). I don't how to do it but I don't notice a problem with my microphone.

Did you ever get this sorted? Getting the same fault on my G42 M240i.

No I didn't. Might ask the dealer when I visit them next

Had that on my 5 series and it went away after I updated to latest 07/2023 release. Seemed like a false error.
