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.
A571624 2042941-2017-10-25. Service bulletin. EQUIPMENT ADAPTIVE/MOBILITY. The vehicle was delivered with two remote keys that have different exterior finishes. One key has a glossy piano black finish with matte chrome detail, and the other key has a completely matte black finish. Starting model year 2016 TT vehicles and with model year 2017 Q7 and A4 vehicles, vehicles equipped with Audi advanced key (Kessy) will be delivered with two remote keys that have different exterior finishes. Delivering vehicles with two keys that have different finishes is done deliberately. The key with glossy black finish indicates that the vehicle is equipped with Audi advanced key. Vehicles without Audi advanced key are delivered with two matte black finish keys.
A571623 2041396-2017-10-25. Service bulletin. EQUIPMENT. The plastic emergency spare key was not delivered with the vehicle. From MY 2016, the plastic emergency spare key is no longer part of the standard equipment for vehicles with the newest keyless remote design. Keyless entry is standard on all new Audi models, and the metal key in the remote is considered the emergency key for accessing the vehicle.

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.
