| 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. |
| A871237 2020124- | 2017-11-08. Service bulletin. EQUIPMENT:APPLIANCE:AIR CONDITIONER; VISIBILITY:DEFROSTER/DEFOGGER/HVAC SYSTEM; ELECTRICAL SYSTEM. Supersedes Technical Service Bulletin Group 87 number 12-32 dated September 5, 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 J519 Central Electrics Control unit 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 Vehicle Electrical System Control Module J519. Vehicle Electrical System Control Module J519 transfers the information provided by the sensor via the comfort data bus to Climate Control Module J255. |
| A011255 2030192- | 2017-11-08. Service bulletin. ENGINE AND ENGINE COOLING; ELECTRICAL SYSTEM. MIL light on. P2015 sender of intake manifold flap position/air flow control, implausible signal P2020 sender of intake manifold flap position, intake manifold flap 2, implausible signal. Engine may have reduced performance without significant loss of power or stalling. Check service history to see if the improved ? B? suffix V157 Intake Flap motor has already been installed previously; if yes, only replace the potentiometer seals as described below. The fault entry is made because a linkage of the intake manifold flap adjustment sticks. This is caused by deformed oil seal behind the potentiometers. |
| A911263 2021151- | 2017-11-08. Service bulletin. ELECTRICAL SYSTEM; EQUIPMENT:APPLIANCE:AIR CONDITIONER. Supersedes Technical Service Bulletin Group 91 number 11 ? 83 dated April 15, 2011. The customer may report that the illumination of the dash insert, the air conditioning control panel or the inside light flickers when briefly pressing the accelerator in P or N or when shifting down while driving downhill. Only vehicles with PR number 8GH may be affected. When high electricity consumers are switched off and the battery is fully charged, the energy generated by the alternator is sometimes too great for the power system to absorb. This may lead to briefly increased voltage, and the lights mentioned above may briefly flicker. This characteristic is caused by the alternator design and is a normal condition of the vehicle. |
| A571281 2020472- | 2017-11-08. Service bulletin. ELECTRICAL SYSTEM; EQUIPMENT. Supersedes Technical Service Bulletin Group 57 number 10-38 dated December 1, 2010. One or more door handle touch sensors cannot be used to unlock the vehicle doors. Through diagnosis it has been determined that a door handle touch sensor must be replaced. Otherwise, the vehicle locks function normally, such as when using the remote key or the interior lock switch. It is possible incompatible door handle touch sensors are installed. This could be due to either the door handle touch sensors or the Central Comfort System control unit J393 (address word 46) having been replaced previously. |
| A901238 2032113- | 2017-11-08. Service bulletin. ELECTRICAL SYSTEM; EQUIPMENT. The customer may state that the outside ambient temperature display is incorrect. To achieve a smoothening effect of the displayed outside ambient temperature, the value shown does not instantaneously follow the temperature sensor measurement. The display will not change faster than 4° F (2° C) per minute. This concept applies to both falling and rising temperatures. A programming strategy is also implemented to avoid incorrect readings on a parked vehicle, due to the temperature sensor being affected by outside influences such as radiant heat from the engine bay, elevated road surface temperatures, etc. |
| A001466 2037949- | 2017-11-08. Service bulletin. ELECTRICAL SYSTEM:SOFTWARE. A DTC with the description ?Invalid Data Record? is stored after an ECU has been replaced or updated. This DTC is normal. It indicates that the parameter data has not been properly programmed into the ECU by SVM. |
| A001465 2011732- | 2017-11-08. Service bulletin. ELECTRICAL SYSTEM:SOFTWARE. Supersedes Technical Service Bulletin Group 00 number 12-32 dated February 7, 2012. This Technical Service Bulletin (TSB) details the general process for carrying out a Software Version Management (SVM) software update for any TSB or Update. |
| A641433 2029714- | 2017-11-08. Service bulletin. ELECTRICAL SYSTEM:SOFTWARE. Supersedes Technical Service Bulletin Group 64 number 12-22 dated July 5, 2012. After one or both of the front door control units (J386/J387) is replaced, one or both of the rear door control units (J3888/J389) cannot be coded or parameterized via an SVM specified vs. actual comparison (spec/actual). The parameter data in the software coding container has changed for the front and rear door control units. As a result, an SVM code is required to update the parameter data for any replacement control unit. Simply running an SVM spec/actual will not code nor update the parameter data in the new replacement control unit. A hardware change suggestion will be provided when an SVM spec/actual is executed. An additional hardware replacement is not required. |
| Customer Letter | 2017-11-08. Service bulletin. ELECTRICAL SYSTEM: INSTRUMENT CLUSTER/PANEL. Audi has determined that, under specific conditions, the turbocharger could malfunction and may cause the Malfunction Indicator Lamp (MIL) on the instrument cluster to illuminate due to the presence of specific fault codes caused by this component. The MIL is part of your on-board diagnostic system. Please refer to your owner's manual for additional information about the MIL. In some locales, an illuminated Malfunction Indicator Lamp could cause your vehicle to fail an IM emissions inspection, and your vehicle registration application could be denied. Please be aware that other conditions (unrelated to the issue described in this letter) may cause the MIL in your vehicle to illuminate. Customers should be prepared to cover all diagnosis and repair costs for these other, unrelated conditions. Dealers will diagnose and replace a faulty turbocharger if necessary, at no cost to you as long as the vehicle remains within the time and mileage limits of this warranty extension. |
| A911437 2030947- | 2017-11-08. Service bulletin. EQUIPMENT:ELECTRICAL; ELECTRICAL SYSTEM:SOFTWARE. Supersedes Technical Service Bulletin Group 91 number 13-92 dated July 16, 2013. 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 receives 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 because it assumes that the phone is not responding. |
| A171449 2028440- | 2017-11-08. Service bulletin. ELECTRICAL SYSTEM: INSTRUMENT CLUSTER/PANEL. Supersedes Technical Service Bulletin Group 17 number 12-26 dated January 20, 2012. 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. |

Supersedes Technical Service Bulletin Group 01 number 12-55 dated October 22, 2012. MIL on. DTCs are stored in the engine control module (ECM). Engine may have reduced power without significant loss of power or stalling. A deformed oil seal behind the potentiometer causes a linkage of the intake manifold flap adjustment to stick, which sets the DTCs. When the potentiometer is removed, the oil seal can be seen. |
| Customer Letter | 2017-10-31. Service bulletin. ELECTRICAL SYSTEM: INSTRUMENT CLUSTER/PANEL. 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. In our continuing efforts to assure proper performance of Audi vehicles, your dealer will diagnose and replace a faulty fuel injector, if necessary, at no cost to you as long as the vehicle remains within the time and mileage limits of this warranty extension. Please keep this letter with your Warranty booklet and deliver it to any new owner, along with the owner?s manual. |

After the airbag control module (J234) has been replaced, the control unit cannot be coded via SVM spec/actual. An SVM code is required to code and parameterize the new service replacement airbag control module. Each model?s SVM code is provided in a parts bulletin (GP bulletin), which should have been referenced through ETKA when the module was replaced. The control module cannot be coded until the SVM code has been executed. |
| A271319 2029010- | 2017-10-31. Service bulletin. ELECTRICAL SYSTEM:12V/24V/48V BATTERY. Supersedes Technical Service Bulletin Group 27 number 12-13 dated March 22, 2012. The customer may report a discharged battery when trying to start the vehicle. The condition results in a no start. |
| A271318 2023282- | 2017-10-31. Service bulletin. ELECTRICAL SYSTEM:12V/24V/48V BATTERY. Supersedes Technical Service Bulletin Group 27 number 12-10 dated February 13, 2012. Battery testing and charging for vehicles equipped with a Battery Data Manager (BDM - J367). When the InCharge 940 is used as a battery charger in auto mode, it performs a battery condition test and may prematurely fail the battery if the charging takes place at the jumper posts in the engine compartment. This is due to the added resistance in the system between the battery and jumper posts. When the InCharge 940 is used as a battery charger in manual mode, the battery condition test is not performed. |
| A911598 2018187- | 2017-10-27. Service bulletin. ELECTRICAL SYSTEM. Supersedes Technical Service Bulletin Group 91 number 14-50 dated July 10, 2014. Customer may report that cracking, grinding, rattling, humming, whining, or similar interference is coming from one or more speakers. Parts of the speakers (such as the brackets, cables, or covers) or parts of the interior fittings (such as door covers, rear shelf, facings, or covers) can vibrate at certain frequencies, causing noises. The radio tuner or other control modules may be affected by electromagnetic interference from aftermarket electronic devices. |
| 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. |
| 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. |
