A humming noise can be heard from the hands-free microphone of the 9ZF phone preparation system. This interference noise changes when the interior light is switched on. This only occurs in vehicles where the microphone is located in the interior light.

Cause:
External interference affecting the microphone.

Solution:
Replace the microphone with one featuring special shielding (Index A).
Tschüss
