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.

AWA-13-092017-12-05. Service bulletin. FUEL SYSTEM, GASOLINE:FUEL INJECTION SYSTEM. Audi has determined that a faulty fuel injector may cause minor misfire conditions and, in turn, cause the Malfunction Indicator Lamp (MIL) on the instrument cluster to illuminate due to the presence of specific fault codes caused by this component. Please note that it is highly unlikely that the vehicle will experience an issue with multiple fuel injectors at the same time. The MIL is part of the on-board diagnostic system. Please refer to the owner's manual for additional information about the MIL. In some locales, an illuminated Malfunction Indicator Lamp could cause the vehicle to fail an IM emissions inspection, and the vehicle registration application could be denied. Be aware that other conditions (unrelated to the issue described in this bulletin) may cause the MIL in the vehicle to illuminate. Customers should be prepared to cover all diagnosis and repair costs for these other, unrelated conditions. This warranty extension covers only the diagnosis and replacement of a faulty fuel injector.
A201559 2011703-2017-11-17. Service bulletin. FUEL SYSTEM, DIESEL; FUEL SYSTEM, GASOLINE. Supersedes Technical Service Bulletin Group 20 number 13-29 dated November 15, 2013. The fuel tank has been removed from the vehicle and must be neutralized before shipment or disposal. When the fuel tank in a vehicle is replaced, the original tank must be properly flushed to neutralize the remaining gasoline or diesel fuel.
A171568 2028440-2017-11-17. Service bulletin. ELECTRICAL SYSTEM: INSTRUMENT CLUSTER/PANEL; FUEL SYSTEM, GASOLINE:STORAGE:TANK ASSEMBLY. Supersedes Technical Service Bulletin Group 17 number 14-49 dated April 3, 2014. When the vehicle is completely refueled, the vehicle range (?distance to empty?) that is displayed is different than the vehicle range that was displayed the last time the vehicle was completely refueled. The displayed vehicle range drops inconsistently. After the vehicle is refueled, the displayed vehicle range does not change for a long period of time. When the vehicle is driven on hilly roads for a long period of time, the displayed vehicle range suddenly changes by a significant amount. There are no DTCs related to fuel senders stored in the instrument cluster control module, J285 (address word 17). This condition does not involve or affect the accuracy of the fuel level indicator, but only the estimated distance to empty display on the on-board computer.
A011309 2014753-2017-11-17. Service bulletin. ELECTRICAL SYSTEM; FUEL SYSTEM, GASOLINE. Supersedes Technical Service Bulletin Group 00 number 10-01 dated February 5, 2010. Excessive accumulation of deposits on intake valves, intake manifold, fuel injectors and combustion chambers. Engine runs rough after cold start. Excessive engine cranking time. Hesitations while driving. Rough engine idle. Reduced engine performance. Poor fuel economy. Conditions may be severe enough to illuminate the MIL in conjunction with storage of DTCs for misfire (example: P0300, P030x) and / or lean fuel system (example: P0171, P0174, P1128, P1130, P1136, P1138) in the engine control module (ECM). Condition may be caused by use of contaminated gasoline. Condition may be caused by use of gasoline with a low content of deposit control additives.
A201225 2031607-2017-11-08. Service bulletin. FUEL SYSTEM, GASOLINE; EQUIPMENT. The instrument cluster displays a fuel range of zero miles before the fuel tank is completely empty. Upon refueling at a displayed fuel range of zero miles, the fuel tank accepts fewer gallons than what is shown in the owner? s manual capacity chart. To ensure mobility, a small amount of fuel is still available when a fuel range of zero miles is initially displayed. Additionally, the fuel range is calculated based on the most recent driving style. Therefore, the actual amount of fuel remaining may vary when a fuel range of zero is initially displayed.
Dealer Letter -2017-10-21. Service bulletin. FUEL SYSTEM, OTHER:DELIVERY:FUEL PUMP. This document contains general information on the upcoming warranty extension on the high pressure fuel pump.

The use of contaminated gasoline or gasoline with a low content of deposit control additives may result in excessive accumulation of deposits on intake valves, intake manifold, fuel injectors, and combustion chambers, engine running rough after cold start, excessive engine cranking time, hesitations while driving, rough engine idle, Reduced engine performance, and/or Poor fuel economy. Conditions may be severe enough to illuminate the MIL in conjunction with storage of DTCs for misfire, lean fuel system, or air/fuel ratio imbalance in the engine control module. Condition may be caused by use of contaminated gasoline. Condition may be caused by use of gasoline with a low content of deposit control additives.
