Noises and inconsistent engine operation after cold start during the catalyst heating phase. The customer may misinterpret these symptoms as engine misfiring. This bulletin applies only to non-diesel engines.
Dealer Letter -2017-10-21. Service bulletin. EQUIPMENT ADAPTIVE/MOBILITY. This document contains the letter sent from Audi Customer Protection to Audi dealerships regarding the updated expiration date for Service Action 20U3.
Circular - 20U32017-10-21. Service bulletin. FUEL SYSTEM, DIESEL. Expiration date extended for U.S. only. As diesel engine passenger vehicles become more popular, auto manufacturers have seen an increase in the number of misfueling cases where diesel engine vehicles are mistakenly fueled with gasoline. The resulting fuel system contamination can lead to costly repairs that are not covered under warranty.
A971548 2013504-2017-10-21. Service bulletin. ELECTRICAL SYSTEM. Supersedes Technical Service Bulletin Group 97 number 10-15 dated October 20, 2010. Sporadic fault memory entries are stored in various control modules. Contacts may be widened (over 0.63 mm) if incorrect pins or incorrect methods for current flow tests are used. Either action may cause intermittent electrical connections, which can cause sporadic DTCs to be stored in various control modules.
A941567 2027773-2017-10-21. Service bulletin. EXTERIOR LIGHTING. Supersedes Technical Service Bulletin Group 94 number 12-96 dated November 1, 2012. Part or all of the daytime running lights do not work on vehicles equipped with LED daytime running lights. For vehicles with halogen daytime running lights, refer to TSB 2017488: 94 Halogen Daytime running lights do not work. In the past, the daytime running light bulbs were a serviceable part. In this application, the LED strip cannot be replaced, and may have an associated control module. This TSB is for servicing information only.
A911588 2026390-2017-10-21. Service bulletin. EQUIPMENT:ELECTRICAL; EQUIPMENT:ELECTRICAL:RADIO/TAPE DECK/CD ETC.. When a phonebook with a large number of contacts is being downloaded, the MMI screen freezes Briefly after the initial Bluetooth connection (shortly after the phone is bonded to the vehicle), after the ignition is switched on (shortly after the phone automatically reconnects with the vehicle), and after the phonebook has downloaded. When the voice recognition system is used, a message appears in the MMI screen stating that the phone book is too large and that the voice recognition system cannot be used. When music is streamed to the MMI system with the Bluetooth A2DP connection, the music intermittently pauses or seems to skip. The condition goes away once the phonebook transfer is completed. The MMI uses a limited portion of the total memory to convert the name and phone number fields of downloaded contacts into a voice command (text to speech). Extensive processing takes place if too many letters are used in the first and last name fields or if numbers or special characters are entered. The remaining memory is dynamically assigned to different applications which can also affect the capacity of the voice command processing. The MMI does not respond until the process is completed or it may freeze if phonebook fields are too large or do not follow typical formatting. In addition, the text-to-speech capacity is exceeded and the voice recognition system is rendered inactive.
A871563 2010146-2017-10-21. Service bulletin. EQUIPMENT:APPLIANCE:AIR CONDITIONER. Supersedes Technical Service Bulletin Group 87 number 14-54 dated August 28, 2014. There is an unpleasant, musty odor coming from the heating and ventilation system. The odor usually occurs when the vehicle has been sitting unused for five hours or more. The odor usually occurs within 20 to 60 seconds after the vehicle is started. Condensation, which is a normal condition in all A/C systems, can cause a musty odor. If the odor is noticeable in the vehicle when the engine is not turned on, the cause may be mold and mildew in the passenger compartment, and not be related to the A/C system. All other possible sources of the odor must be investigated before this bulletin can be performed.
Dealer Letter-Da2017-10-21. Service bulletin. ENGINE AND ENGINE COOLING:EXHAUST SYSTEM:EMISSION CONTROL. This document contains information about the upcoming emissions service action 23N4.
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.
Campaign Circula2017-10-21. Service bulletin. ENGINE AND ENGINE COOLING:EXHAUST SYSTEM:EMISSION CONTROL; ELECTRICAL SYSTEM:SOFTWARE. The vehicle's engine management software has been improved to assure the vehicle's tailpipe emissions are optimized and operating efficiently. Under certain operating conditions, the earlier strategy may have increased the chance of the vehicle's MIL light illuminating. If the MIL illuminates for any reason, the vehicle will not pass an IM emissions inspection in some regions. ECM software update needed.
A941565 2012749-2017-10-21. Service bulletin. EXTERIOR LIGHTING:HEADLIGHTS. Supersedes Technical Service Bulletin Group 94 number 12-92 dated October 24, 2012.

The picture looks too bright, too dark, or opaque in certain areas of the image. The colors of the objects in the image are incorrect or slightly off. The guidelines used for parking are fuzzy, distorted, or pixelated when compared with the guidelines displayed on another vehicle?s MMI.
A741521 2036572-2017-10-21. Service bulletin. SEATS. Supersedes Technical Service Bulletin Group 74 number 14-19 dated May 9, 2014. The panel on the back of the front seat is warped or dented. The headrest on the rear seatback may also be damaged. The damaged is caused when the headrest of the rear seat backrest comes in contact with the back of the front seat. This occurs when the rear seat is folded down with the headrests installed, and the front seat is moved back far enough to make contact with the rear seat headrest.
A911579 2038824-2017-10-21. Service bulletin. ELECTRICAL SYSTEM. Supersedes Technical Service Bulletin Group 91 number 14-69 dated November 4, 2014. The following message appears on the MMI display: "Device or cable type not supported". The AMI cable being used is a genuine Audi-branded cable with an Audi part number (see Required Parts and Tools for a list of valid part numbers). The "Device or cable type not supported" message may be displayed when an incorrect AMI cable type is connected to the MMI system. Only cables with an Audi part number (i.e., 4F0.XXX.XXX) are supported by the MMI system. Volkswagen-branded cables look similar, but are not guaranteed to work with Audi MMI systems. The label on the end of an Audi-branded cable has an Audi logo and Audi part number. Audi-branded cables have unique firmware inside the hardware that can determine which MMI system and iOS device are connected to the cable. Volkswagen cables do not have this firmware. The firmware is required to allow the system to function normally due to the different technology available in the different MMI systems and in the different iPhones and iPod Touch devices. In addition, the AMI system was designed to play the music stored locally on the connected device only. Music streaming (from Spotify or Pandora, for example) is not supported, and music stored in the cloud (on Google Play, Amazon Prime, or iTunes Match/iCloud, for example) may drop out, pause, and skip when played.

Customer states that the reception of satellite radio occasionally fades or drops out. The information display may show a message related to the satellite radio, such as "Linking", "Updating", "Acquiring Signal", "Loading", "No Signal", or "No Sat".
A171557 2010043-2017-10-21. Service bulletin. ENGINE AND ENGINE COOLING. Supersedes Technical Service Bulletin Group 17 number 13-35 dated January 9, 2013. This bulletin lists engine oils that meet Audi oil quality standards (VW 501 01, 502 00, 505 00, 505 01, and 504 00/507 00).
A101511 2018288-2017-10-21. Service bulletin. ENGINE AND ENGINE COOLING. Supersedes Technical Service Bulletin Group 10 number 13-10 dated September 5, 2013. Prior to engine replacement, any debris lodged in transferred assemblies must be removed. If the engine experienced a serious mechanical problem, it is possible that small pieces of metal debris resulting from the mechanical problem may have become deposited in the intake manifold, air intake hoses, exhaust manifolds, exhaust down-pipes, turbocharger, supercharger, and/or intercooler. If these metal debris pieces are not removed prior to the installation and operation of the replacement engine, they could be drawn into the combustion chamber, which can cause a knocking noise and subsequent serious engine damage.
A011514 2014753-2017-10-21. Service bulletin. FUEL SYSTEM, GASOLINE. Supersedes Technical Service Bulletin Group 01 number 13-09 dated June 21, 2013.
