# Service bulletin A911520 2039515\-

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.

## NHTSA's summary

Supersedes Technical Service Bulletin Group 91 number 15\-07 dated July 28, 2015. The customer complains that the Audi connect online service in their 2012\-2013 A6 or A7 vehicle only reaches 2G service. This bulletin applies only to model year 2012\-2013 A6 and A7 vehicles. For other models, see TSB 2039476. This bulletin does not apply to model year 2014 or newer. Starting with model year 2014, the new telephone module was installed in production. 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 certain metropolitan areas. 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.
