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.
