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?

I got the same error after coding as well. I cleared the fault and it hasn’t came back

I had this fault also, after calibrated the mic using ISTA+ the fault still existed. But after programed the RAM module the fault gone.

how did you program the RAM module to clear this fault?

You can use Esys to flash the RAM module.

I bought this over the summer and it's pretty cool. I was having the Mic not calibrated error, and used Bimmer Utility to reset the RAM ECU. Quick and easy, and the error went away. I'll let you all know if it comes back. At least for now it's seems to have worked.
