A911634 2043660-2017-10-25. Service bulletin. ELECTRICAL SYSTEM:SOFTWARE. The customer has various complaints about the RSE system and would like to update the software of the RSE tablets. The vehicle cannot be started after it has been off for several days, and there are no indications in the battery history log of battery drain originating from a control unit on the CAN bus. The latest update (available as of March 2016) implements a fix that can prevent one of the RSE units from staying awake while the ignition is off, which can potentially draw the vehicle battery down.
A911633 2037809-2017-10-25. Service bulletin. ELECTRICAL SYSTEM:SOFTWARE. The navigation map does not show the latest roads or points of interest. The map download provided by the myAudi website cannot be performed. The customer does not know how to obtain the data or cannot perform the update after downloading the data. The MMI is slow to respond or freezes during the map update. For vehicles with MIB2, the MMI over-the-air map update does not allow for a full map update and shows greyed-out regions. The customer is concerned that the OTA map update will consume too much data from the Audi connect data subscription.

A961604 2042811-2017-10-04. Service bulletin. ELECTRICAL SYSTEM:SOFTWARE. Audi connect Gen1 and Gen2 systems: Differences and troubleshooting. The customer has a general concern related to Audi connect. Different features are included with different generations of the Audi connect system. The Audi connect Gen1 system includes all vehicles that utilize a removable plastic SIM card. The Audi connect Gen2 system includes all vehicles that utilize an embedded SIM card. The root cause of all complaints cannot be attributed to the vehicle hardware because of the backend server configurations that need to be correct in order for Audi connect to work. For most sporadic complaints, the issue typically resides with the MBB backend server or with the source data provider (Google, INRIX, etc.), and not with the vehicle. In rare cases, the mobile network operator (AT&T, T-Mobile) can be the cause of the complaint. For most static complaints, the issue can be attributed to the user account subscription or possibly the vehicle hardware.
