| A011369 2028344- | 2017-11-17. Service bulletin. ENGINE AND ENGINE COOLING:EXHAUST SYSTEM; ENGINE AND ENGINE COOLING. Supersedes Technical Service Bulletin Group 01 number 12-57 dated October 29, 2012. Noises/inconsistent engine operation after cold start during the catalyst heating phase. The customer may interpret this engine roughness as misfiring. To comply with the legal requirements on exhaust gas emissions according to the LEV-1 and LEV-2 standards, a high exhaust gas quality must be ensured. The necessary catalyst only operates at a temperature over 300°C (572°F). To achieve this, the catalyst is heated up. The catalyst heating phase is achieved by a late ignition angles and by introducing additional fresh air to the exhaust valves (secondary air system). Late ignition angles make sure that the exhaust gas from the cylinders has a higher temperature. This exhaust gas includes fuel that is un-burnt, and was deliberately injected into great quantities. The secondary air system adds fresh air to the exhaust gas as it leaves the cylinder and the extra fuel is burnt. As a result, the temperatures of the exhaust gas and of the catalyst increase quickly. The afterburning in the exhaust manifold before the catalyst changes the sound characteristic of the engine. This heating-up of the catalyst, including afterburning, is normal and has no effect on the service life of the engine. During this catalyst heating phase, the engine has increased idle speed, may have increased vibrations, and has a different sound characteristic. Depending on conditions, the time of the catalyst heating phase varies. |

Supersedes Technical Service Bulletin Group 47 number 10-01 dated July 15, 2010. Muh? sound or moaning noise coming from the front brakes (FNRG). The performance of the brakes is not compromised. The pistons in the calipers in certain vehicles may not retract far enough, which may leave contact between the rotor and pad. This contact may cause a ?muh? sound or moaning noise in low speed conditions. |
| A571385 2017082- | 2017-11-17. Service bulletin. ELECTRICAL SYSTEM; LATCHES/LOCKS/LINKAGES:DOORS:LATCH. Supersedes Technical Service Bulletin Group 57 number 13-82 dated February 5, 2013. Central locking via remote control does not work either sporadically or permanently. The locks can still be operated manually. Missing synchronization between the remote control key and vehicle because the battery has been disconnected or the battery of the remote control has been replaced. If other senders operate in the same frequency range (mobile phones, TV stations, wireless headphones, baby monitors, other vehicle remote controls, etc.), the remote control key may have been temporarily switched off because a clear identification of the remote control key is not possible. This is necessary to prevent an unintentional unlocking of the vehicle by other unrelated senders. |
| A961501 2019260- | 2017-11-17. Service bulletin. ELECTRICAL SYSTEM:SOFTWARE. Supersedes Technical Service Bulletin Group 96 number 13-67 dated July 10, 2013. The customer may report that the handheld transmitter cannot be programmed to the garage door opener control module, J530. The customer?s door opener system may not be compatible with J530. The battery in the handheld transmitter may be too weak for a good signal. The battery charge may be sufficient to operate the garage door opener, but not enough to program the remote transmitter to the vehicle system. The battery in the handheld transmitter may be too weak for a good signal. The battery charge may be sufficient to operate the garage door opener, but not enough to program the remote transmitter to the vehicle system. In A4 model years 2005?2006 and A3 model year 2009, the actual location of the garage door opener control module differs from the location shown in the owner's manual (opposite side of front bumper). The customer may misunderstand the programming procedure, particularly if the customer?s HomeLink® opener system is using an alternate code. The handheld transmitter?s programming function may become inoperative, or the transmitter is too far away from J530. Interference prevents the communication between handheld transmitter and J530. Interference prevents the communication between handheld transmitter and J530. If the vehicle flashes during the programming of a handheld transmitter, this does not necessarily indicate that the programming was successful; it only indicates that the vehicle has recognized and saved a signal. |
| A481567 2017266- | 2017-11-17. Service bulletin. ELECTRICAL SYSTEM. Supersedes Technical Service Bulletin Group 48 number 14-62 dated September 23, 2014. Electrically-adjustable steering column adjustment is restricted and does not adjust vertically. Incorrect operation of Easy Entry is not the cause. It is unlikely that external forces have led to the loss of the stored end positions of the adjustment movement. See TSB 2015819, 48 Easy Entry function of the power adjustable steering column intermittently does not work, for more information. Seat adjustments can be used to maintain the 10-inch minimum recommended distance from the steering wheel in case of airbag deployment. The axial adjustment is still functional during this condition. The steering column may be under tension due to unfavorable tolerances of the steering column and module cross carrier. As a result, the current draw of the regulator motors is above specification, which causes the electric steering column adjustment to fail. Once the vehicle electrical system control module, J519 (address word 09), detects an excessive current draw, the basic settings will be erased. If basic settings are not stored in the vehicle electrical system control module, the module will not send voltage/current to the motor to operate the vertical adjustment. |
| A191562 2025303- | 2017-11-17. Service bulletin. ENGINE AND ENGINE COOLING. Supersedes Technical Service Bulletin Group 19 number 15-61 dated July 7, 2015. Discontinuation and mixing of Audi-approved engine coolants. G11, G12, and G12+ coolants have been replaced by an improved version. G12++ coolant (for service available) has been introduced in MY 2005 for all engines. G13 has been introduced in MY 2008 as factory filling and service. |
| A911526 2042097- | 2017-11-17. Service bulletin. EQUIPMENT:ELECTRICAL:NAVIGATIONAL SYSTEM(GLOBAL POSITIONING SYSTEM). The traffic feature in the MMI navigation is inoperative. If the vehicle is a model year 2016 A6 or A7, see TSB 2042013: 91 Audi connect online destination search, Google Earth navigation view, or INRIX online traffic is not available. There is a known server issue that can only be resolved through a change to the Audi AG backend server. Audi has changed traffic providers over the years as new technologies have developed.

| 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. |
