If you coded enhanced bluetooth you will have error of not having the other microphone as enhanced bluetooth has.

There is no such things as maximum 20 errors stored, you can read as many as the car has. What does your ecu tree say? Looks like a discommunication with ZGW at some point. What verision of ISTA+ do you have?

Just go ahead and clear the faults
