Service bulletin A911586 2039476-

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 15-76 dated March 3, 2015. The customer complains that the Audi Connect Online service in their 2011-2013 A8, 2012-2013 Q7, or 2013 A4, A5, A5 cabriolet, or Q5 vehicle only reaches 2G service when some metropolitan areas. This bulletin applies only to model year 2011-2013 A8, 2012-2013 Q7, and 2013 A4, A5, A5 cabriolet, and Q5 vehicles. For 2012-2013 A6 and A7 vehicles, see TSB 2039515. 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 the vehicles to which this bulletin applies) 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.

Listing a model year does not mean every vehicle of it is concerned: the document says which.

A recall listed here may apply to some of the same vehicles. Only the manufacturer can say whether it applies to one vehicle.
