DESCRIPTION:
There may intermittently not be any sound from the High Performance AUD (Audio Amplifier) after an Infotainment system start-up.
PRODUCT MODIFICATION:
Analysis has shown that the AUDs DA (Digital/Analogue) converter may, under certain circumstances, enter an undesired state, resulting in no sound output. An improved AUD software has been developed. This AUD High Performance software has been released (2012-04-19) for aftersales to prevent this symptom. This same software was introduced into production in 2012w35 with chassis number 658513.
SERVICE:
If the described symptom occurs, please perform an AUD Upgrade to remedy it.
