| A921510 2038151- | 2017-10-21. Service bulletin. VISIBILITY:WINDSHIELD WIPER/WASHER. Supersedes Technical Service Bulletin Group 92 number 14-09 dated September 12, 2014. The washer solvent level warning is on in the DIS, but the washer solvent level is correct. There is no functional restriction in the windshield washer system. The sensitivity of the washer solvent level sensor (G33) can be affected by the type, concentration, and the presence of additives in the washer solvent currently in the tank. The operation of the level sensor relies on the composition of the solvent to provide an accurate message on the solvent level. Incorrect concentration and the presence of additives can contaminate the sensor and reduce its sensitivity. |

| 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. |
| A911587 2040406- | 2017-10-21. Service bulletin. EQUIPMENT:ELECTRICAL:NAVIGATIONAL SYSTEM(GLOBAL POSITIONING SYSTEM). When the vehicle is started, the GPS location or vehicle direction indicated on the MMI navigation map does not match the vehicle's actual location or direction of travel for a long period of time (often as long as 10 minutes). The issue occurs in open sky, with no large buildings obstructing the sky view. The issue is intermittent, but it can occur for long periods of time during a single day. The issue typically happens on very warm days when the HVAC system blower is at a medium to high setting (auto or manual), with air being directed out of the panel vents. When the issue occurs, the GPS navigation system satellite reception shows 0 satellites. Due to the infrequency of the issue, this might not be verifiable. No DTCs related to the GPS antenna or MMI system are present. If the sky view is blocked because the vehicle is in a parking structure, below ground, or next to large buildings, it is normal for the GPS location or vehicle direction indicated on the MMI navigation map to not match the vehicle's actual location or direction of travel. The blocked sky view prevents the vehicle from receiving satellites, and the system may be temporarily lost until four satellites can be received. This is a normal condition, and is not related to the condition described above. Replacing the MMI main unit will not change this behavior. A potential failure in the internal hardware of the MMI main unit can cause the GPS signal to be blocked, even if good reception is available. The failure can happen at start-up or while the vehicle is being driven. The issue typically starts when the vehicle is driven on curvy or circular roads, driven in circles (such as when driven around a parking lot), or driven on or off an expressway. |

| 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. |
| A661553 2038652- | 2017-10-21. Service bulletin. STRUCTURE:BODY. Supersedes Technical Service Bulletin Group 66 number 15-45 dated January 20, 2015. The paint is flaking off of the radiator grille or front license plate holder. The surfaces of these components were too smooth (due to high-gloss polishing tools), which led to weak adhesion of the paint during production. Only components with color index T94 are affected. |

Audi of America (in conjunction with AUDI AG) is conducting a pilot program in the USA with a limited number of specially-built vehicles. These vehicles have a persistent internet connection and are designed to be accessed and started without the need for a traditional remote key. Instead, these vehicles use NFC (Near-field connectivity), or an iPhone with the Audi on Demand app, utilizing Bluetooth connectivity. The customer must leave the NFC card with the vehicle in order for the vehicle to be accessed and started. |
| A961594 2035047- | 2017-10-21. Service bulletin. LANE DEPARTURE: ASSIST; LANE DEPARTURE. Supersedes Technical Service Bulletin Group 96 number 13-79 dated December 5, 2013. Audi side assist deactivates or is sporadically inoperative when the vehicle is driven in slow-moving stop-and-go traffic, especially on roads with multiple lanes. The message "Audi side assist unavailable: Sensors blocked" appears in the driver information panel. The system can be activated approximately ten minutes after the traffic condition is removed, or after an ignition cycle. Workshop finds that sporadic DTCs are stored in the lane change assistance control module, Audi side assist can be activated without issue, no obstructions found on the outside or inside of the bumper, no rework of the bumper can be found, the control module mounting brackets are securely fastened to the lower rear bumper, and no damage is found on the inside or on the outside rear bumper area, and the control module mounting brackets are not broken or loose. |

| A911580 2036575- | 2017-10-21. Service bulletin. EQUIPMENT:ELECTRICAL; EQUIPMENT:ELECTRICAL:NAVIGATIONAL SYSTEM(GLOBAL POSITIONING SYSTEM). Supersedes Technical Service Bulletin Group 91 number 14-27 dated March 4, 2014. The addresses and contacts stored in the Navigation >> Favorites, Navigation >> Directory, and Navigation >> Last destinations submenus disappear intermittently. Intermittently, the MMI system does not appear to remember that the user's myAudi PIN has already been entered, and it requires the user to enter the PIN again. The voice recognition system does not easily recognize commands spoken by the driver. This condition can be consistent or intermittent. Multiple voice recognition training sessions can be stored in the MMI for different users when different phones are Bluetooth-paired during each training session. If no phone is paired, the training session will be stored under a default profile. This profile will be used each time the voice recognition system is used without a phone being paired to the MMI. This TSB is informational only and not applicable to any Audi warranty. |
| 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. |

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. 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. |
