| A911469 2038824- | 2017-12-05. Service bulletin. ELECTRICAL SYSTEM:12V/24V/48V BATTERY:CABLES. The following message appears on the MMI display: ?Device or cable type not supported?. The ?Device or cable type not supported? message may be displayed when the wrong AMI cable type is used. See the Service section of this bulletin for an overview of the AMI cables that support iOS devices. |
| A911463 2028190- | 2017-12-05. Service bulletin. EQUIPMENT:ELECTRICAL:NAVIGATIONAL SYSTEM(GLOBAL POSITIONING SYSTEM); ELECTRICAL SYSTEM:SOFTWARE. Supersedes Technical Service Bulletin Group 91 number 13-08 dated September 20, 2013. The customer would like to add a different navigation map database for countries outside of the USA or Canada. The customer would like to change the MMI system language to a different language that is not already supported by MMI. When a song is being played and the track information for that song contains foreign language characters, the driver information system (DIS) in the cluster correctly displays the characters, but the MMI display does not. |
| A911393 2034784- | 2017-12-05. Service bulletin. ELECTRICAL SYSTEM:SOFTWARE; EQUIPMENT:ELECTRICAL. Some telephone numbers that were downloaded via Bluetooth® are stored with additional, unrelated numbers that do not appear in the contact on the customer"s cellular phone. These telephone numbers are displayed incorrectly on the radio display. The software incorrectly stores the downloaded phone numbers. |
| A911392 2030947- | 2017-12-05. Service bulletin. EQUIPMENT:ELECTRICAL; ELECTRICAL SYSTEM:SOFTWARE. Supersedes Technical Service Bulletin Group 91 number 12-61 dated September 25, 2012. The customer complains that when he or she is trying to place a phone call from the vehicle while using a Bluetooth®-connected phone, the phone call disconnects before it begins and an error shows on the MMI display. The message may be "Function not supported" or "Network error". The customer is using a phone with the Android operating system. In addition, Skype®, or another network-based communication software, is installed on the phone. Call can be placed directly from the phone without a problem. When the phone gets the request to place a call from the vehicle, a prompt appears on the phone asking the user to choose how the call should be placed. If the prompt is ignored, the MMI system disconnects the call assuming the phone is not responding. |
| A911388 2021780- | 2017-12-05. Service bulletin. ELECTRICAL SYSTEM; EQUIPMENT:ELECTRICAL:RADIO/TAPE DECK/CD ETC.. Supersedes Technical Service Bulletin Group 91 number 10-70 dated October 26, 2010. Sequence of error messages are seen on the radio display screen after a CD was loaded into or removed from the internal CD drive. "Drive defective. The error could be corrected by resetting it (see radio system owner's manual). Otherwise, contact your Audi dealer." "The CD-drive is damaged and was therefore deactivated." The CD drive cannot be selected in the Source list and is described as "damaged." After the ignition is cycled or a radio reset performed, the CD drive is fully operational. DTC 00468 (CD-ROM Drive -R92- Faulty) is stored in the radio (address word 56). The DTC will be sporadic if the ignition has been cycled or a radio reset performed and will automatically be cleared after 40 ignition cycles without a reoccurrence. Only vehicles with the CAN-based generation 3 radio (Concert (PR 8UQ) or Symphony (PR 8YN)) are affected. |
| A551332 2023967- | 2017-12-05. Service bulletin. ELECTRICAL SYSTEM:WIRING:FRONT UNDERHOOD; LATCHES/LOCKS/LINKAGES:HOOD:LATCH. Supersedes Technical Service Bulletin Group 55 number 13-30 dated May 28, 2013. "Low Oil Level" message is on in the DIS or MMI. The hood must be open for at least 30 seconds for a reset of this message to be performed. The message is not reset in the DIS/MMI because the hood has not been recognized as being opened due to an inoperative hood contact switch. |
| A461347 2034387- | 2017-12-05. Service bulletin. ELECTRICAL SYSTEM; PARKING BRAKE. Customer may report sporadically hearing the parking brake being actuated after the vehicle has been switched off. If the customer does not identify the sound as the sound of the parking brake being actuated, he or she may simply complain of hearing noises from the rear brakes. Ignition is switched off. Steering is locked. Park is selected. Parking brake is not engaged. If the electro-mechanical parking brake is not operated for some time, the free play between brake pads and brake discs increases because of normal brake pad wear. The parking brake control unit performs an automatic correction about every 621 miles (1,000 km). On A8 models, the brake pad thickness is also calculated. |
| A941306 2017806- | 2017-11-17. Service bulletin. ELECTRICAL SYSTEM; EXTERIOR LIGHTING. Supersedes Technical Service Bulletin Group 94 number 12-79 dated June 6, 2012. Light bulb warning light and the message Vehicle lights: malfunction is displayed in the instrument cluster display. DTC 03280 (Light switch position implausible signal) is stored in the vehicle electrical system control module, J519 (09). Exterior lights are functioning properly. If the headlight switch is moved to an intermediate position and remains there, the light bulb warning light and the error message appear after approximately ten seconds. Once displayed, the message turns off after approximately five seconds. The light bulb warning light turns off only after the headlight switch is turned to a defined position, and the status of DTC 03280 is changed to sporadic. After 40 driving cycles without an implausible signal detected, the DTC is automatically cleared. |
| 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. |
| A911518 2016513- | 2017-11-17. Service bulletin. ELECTRICAL SYSTEM:SOFTWARE; EQUIPMENT:ELECTRICAL:RADIO/TAPE DECK/CD ETC.. Supersedes Technical Service Bulletin Group 91 number 10-59 dated September 15, 2010. In Mix (shuffle) mode, very long response times and subsequent malfunctions occur when the next track is being selected. Long response times also occur when the ?Return? hard key is pressed. In Mix (shuffle) mode, the previous track is not played when the ?Previous? button is selected in the CD control menu. A different track plays instead. In Mix (shuffle) mode, when the first track of the playlist was selected via the ?Previous? button in the CD control menu (rather than with the rotary push button), the track list shown in the MMI does not match the track list shown in the driver information panel (synchronization issue). In Mix (shuffle) mode, the current track is not highlighted in white letters in the MMI display. If the current track is selected again via the rotary push button, the audio briefly drops out. The current track is not color-highlighted in the MMI display. Audiobook tracks continuously fast-forward if ?Fast Forward? was selected in the first few seconds after the track started playing. The message ?Device is being initialized. Please wait?? is displayed when a second generation iPod Nano is installed. iPod locks up but is operable again after the iPod is reset. iPod performs a reset and restarts on its own. iPod is not detected when it is plugged into the AMI. The message ?Device or cable type not supported? appears in the MMI display. An automatic iPod upgrade through iTunes contained inoperative driver software. The customer may not realize that the iPod was updated and may complain that the AMI software is causing the issues. Because downgrading the updated iPod software is usually not possible, the AMI driver software (firmware) must be updated. The firmware update of AMI is not a ZUG update. Unlike ZUG updates, which are performed with an update CD in the CD changer, this firmware update is performed with a USB device connected dir |
| A551538 2023967- | 2017-11-17. Service bulletin. ELECTRICAL SYSTEM. Supersedes Technical Service Bulletin Group 55 number 13-32 dated July 30, 2013. ?Low Oil Level? message is on in the DIS or MMI. The hood must be open for at least 30 seconds for a reset of this message to be performed. The message is not reset in the DIS/MMI because the hood has not been recognized as being opened due to an inoperative hood contact switch. |
| A911529 2013422- | 2017-11-17. Service bulletin. ELECTRICAL SYSTEM. Supersedes Technical Service Bulletin Group 91 number 13-04 dated September 11, 2013.

| 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. |
| A011548 2027306- | 2017-11-17. Service bulletin. EQUIPMENT:OTHER:OWNERS/SERVICE/OTHER MANUAL; ELECTRICAL SYSTEM. Supersedes Technical Service Bulletin Group 01 number 14-01 dated October 30, 2014.

After the comfort system central control module, J393 (address word 05) is replaced, the control module cannot be coded via SVM spec/actual. Any time a comfort system central control module, J393 (address word 05), is replaced, the new control module must be coded and parameterized with online SVM spec/actual or an SVM code. If the SVM spec/actual returns a response of ?Check Hardware?, then an SVM code is required to code and parameterize the new control module. The SVM code can be found in Parts Bulletin 9-101, which can be found on the etkainfo.com web site. |
| A241551 2038212- | 2017-11-17. Service bulletin. ELECTRICAL SYSTEM. Supersedes Technical Service Bulletin Group 24 number 14-50 dated August 28, 2014. The engine judders or runs erratically.

Possible incorrect function on the sensor elements of the air mass meter. |
| 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. |
| A301318 2028229- | 2017-11-17. Service bulletin. ELECTRICAL SYSTEM: INSTRUMENT CLUSTER/PANEL. Supersedes Technical Service Bulletin Group 30 number 11-11 dated December 9, 2011. Customer may report that the vehicle does not start or only starts when the clutch pedal is pressed very firmly. The message ?Press clutch pedal to start vehicle? may appear in the instrument cluster. There may be clutch mechanism wear. |
| A851318 2033426- | 2017-11-17. Service bulletin. ELECTRICAL SYSTEM: INSTRUMENT CLUSTER/PANEL. Supersedes Technical Service Bulletin Group 85 number 13-15 dated March 29, 2013. The trim panel at the defroster vent on the instrument panel is deformed. The trim panel is composed of a material which expands in a moist condition. The instrument panel restricts this expansion which leads to deformation of the trim. |
| A871342 2020124- | 2017-11-17. Service bulletin. EQUIPMENT:APPLIANCE:AIR CONDITIONER; ELECTRICAL SYSTEM:12V/24V/48V BATTERY. Supersedes Technical Service Bulletin Group 87 number 12-37 dated November 16, 2012. Air conditioning is inoperative. The HVAC blower functions normally. Battery discharged; however, when charged, there is no bus silence when vehicle ignition is off. The A/C pressure/temperature sensor, G395, leaks refrigerant. This causes sensor G395 to show an incorrect or implausible value when reading MVBs. An incorrect signal or a low refrigerant level in the system can cause the air conditioning compressor to deactivate. The LIN cable connecting the vehicle electrical system control module, J519, to sensor G395 is pinched or cut. This affects the A4/S4, A5/S5 Coupe and Cabriolet, and Audi Q5 vehicles. The A6 and A8 are not affected by this type of failure. The pressure sensor G395/G65 sends an incorrect signal that prevents bus silence and the battery is discharged. Sensor G395 is a LIN slave of the vehicle electrical system control module. The vehicle electrical system control module transfers the information provided by the sensor via the comfort data bus to the climate control module, J255. |
| A961364 2029384- | 2017-11-17. Service bulletin. ELECTRICAL SYSTEM. Supersedes Technical Service Bulletin Group 96 number 12-32 dated April 27, 2012. The customer is able to program one or more of the Homelink buttons using their garage door remote, but after a few days or weeks, one or more of the programmed Homelink buttons no longer function. The LED on the Homelink button that is no longer functioning now flashes slowly, indicating that no programming is stored. The customer?s transmitter operates at 295Mhz. At the workshop, the Homelink system can be programmed to the workshop garage door successfully. No trouble is found. No DTCs are stored in any control units. The garage door opener control module, J530, was designed with an operational frequency range in which the 295Mhz frequency works correctly during the initial programming of the system. Over time, the transmitting frequency can drift out of range (especially in warmer climates), causing the system to lose its programming. |
| A371275 2029808- | 2017-11-08. Service bulletin. ELECTRICAL SYSTEM; POWER TRAIN. Supersedes Technical Service Bulletin Group 37 number 12-53 dated June 11, 2012.
