Affected Vehicles
Condition
The Voice Recognition function does not work.
Only applies to vehicles equipped with 3G MMI with Navigation.
Technical Background
The voice recognition functionality is not loaded correctly upon system startup.
Production Solution
Not Applicable.
Service
During normal operation, the voice recognition commands can take up to 2 minutes to successfully load during system startup. If the complaint only
occurs during this time, this is normal and no repairs should be performed.
1. Perform a language change to reload the voice recognition commands:
^ In the MMI, navigate to Setup >> Settings >> Menu Language.
^ Switch to a different language by selecting a non-highlighted language (Figure 1). The system will load the new spoken cues.
^ Re-select the original language. Again, the system will load the spoken cues.
^ Once original language cues are loaded, retest the system.
2. If voice recognition functionality has not been restored, disconnect power from the 5F module (J794) for 30 seconds to reset the unit. Once
system has started up and loaded the information, retest the system.
3. If the above steps do not resolve the concern, contact the Audi Technical Assistance Center (TAC) for additional guidance.
