    Dear ALL.


    A friend of mine drive A8 and he has a problem with bluetooth handsfree function.

    Paring with his cell phone (iPhone 4) is okay. He can make or receive a phone call.

    He can hear the other person's voice, however, the other person cannot hear his voice.

    His car comes with BOSE audio system.

    Is there any method to check if the mic. for handsfree is damaged via VCDS?

    Thank you for your answer in advance !

    I auto-scanned his A8 and there is one fault code;

    If the mic was not installed you would have a 'mic open circuit' fault code on the phone module.

    Could be a faulty mic so best best bet would be to try a replacement mic.
