Service bulletins for the 2012 Audi A6
A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

| A661554 2025323- | 2017-10-27. Service bulletin. VISIBILITY. Supersedes Technical Service Bulletin Group 66 number 12-20 dated April 9, 2012. A loud noise is heard when the outside mirrors are folded in or out. The noise originates in the metal spring inside the hinge area of the mirror housing. This spring is used for stabilizing the mirror when the vehicle is driven over rough roads to minimize mirror glass shake. When the mirror housing is folded in or out, the spring must turn or twist with the movement of the housing. The bottom and the top of the spring sit on a plastic base and due to increased friction at these contact points, the spring will skip along the plastic base during the folding operation and creates the noise. The normal functionality of the mirror is not affected. |

| A921510 2038151- | 2017-10-21. Service bulletin. VISIBILITY:WINDSHIELD WIPER/WASHER. Supersedes Technical Service Bulletin Group 92 number 14-09 dated September 12, 2014. The washer solvent level warning is on in the DIS, but the washer solvent level is correct. There is no functional restriction in the windshield washer system. The sensitivity of the washer solvent level sensor (G33) can be affected by the type, concentration, and the presence of additives in the washer solvent currently in the tank. The operation of the level sensor relies on the composition of the solvent to provide an accurate message on the solvent level. Incorrect concentration and the presence of additives can contaminate the sensor and reduce its sensitivity. |
| A911588 2026390- | 2017-10-21. Service bulletin. EQUIPMENT:ELECTRICAL; EQUIPMENT:ELECTRICAL:RADIO/TAPE DECK/CD ETC.. When a phonebook with a large number of contacts is being downloaded, the MMI screen freezes Briefly after the initial Bluetooth connection (shortly after the phone is bonded to the vehicle), after the ignition is switched on (shortly after the phone automatically reconnects with the vehicle), and after the phonebook has downloaded. When the voice recognition system is used, a message appears in the MMI screen stating that the phone book is too large and that the voice recognition system cannot be used. When music is streamed to the MMI system with the Bluetooth A2DP connection, the music intermittently pauses or seems to skip. The condition goes away once the phonebook transfer is completed. The MMI uses a limited portion of the total memory to convert the name and phone number fields of downloaded contacts into a voice command (text to speech). Extensive processing takes place if too many letters are used in the first and last name fields or if numbers or special characters are entered. The remaining memory is dynamically assigned to different applications which can also affect the capacity of the voice command processing. The MMI does not respond until the process is completed or it may freeze if phonebook fields are too large or do not follow typical formatting. In addition, the text-to-speech capacity is exceeded and the voice recognition system is rendered inactive. |
| A911585 2039515- | 2017-10-21. Service bulletin. EQUIPMENT:ELECTRICAL. The customer complains that the Audi Connect Online service in their 2012-2013 A6 or A7 vehicle only reaches 2G service when in some metropolitan areas. This bulletin applies only to model year 2012-2013 A6 and A7 vehicles. For other vehicles, see TSB 2039476. Recently, T-Mobile (the service provider for Audi Connect) has repurposed some of the GSM spectrum (3G on 2100Mhz band) to maximize 4G LTE coverage in the Indianapolis metropolitan area. Devices that do not support 3G service on the 1900MHZ band (including MMI main units of model year 2012-2013 A6 and A7 vehicles) will only receive 2G service when the switch is completed. The change currently only affects the markets listed above, but will affect other markets in coming years. This bulletin will be updated to include these markets as changes occur. |
