| A801304 2033806- | 2017-12-05. Service bulletin. EQUIPMENT:APPLIANCE:AIR CONDITIONER; ELECTRICAL SYSTEM:WIRING. Supersedes Technical Service Bulletin Group 80 number 13-03 dated May 13, 2013. Malfunction Indicator Lamp is on. Climate system heating performance is insufficient. Coolant level warning is on. Engine temperature is elevated. "Limp Home" mode is active. Faults are stored in the transmission control module. Coolant loss is found from one or more control valves: N82, N509, or N488. Coolant may have migrated into the wiring harness through the connector and into various control units. Climate system heating performance is insufficient due to coolant loss, or due to a faulty N82 control valve. Inspection of the coolant control valves N82, N509, or N488 reveals the presence of coolant inside the electrical connector. The connectors, wiring harness, and/or connected control units may have been damaged from exposure to coolant. |
| A971337 2034945- | 2017-12-05. Service bulletin. EXTERIOR LIGHTING:HAZARD FLASHING WARNING LIGHTS; ELECTRICAL SYSTEM. The customer may report two or more warning lights are/were illuminated simultaneously. The warning lights may be sporadic, and may not be illuminated by the time the customer brings the vehicle to the workshop. CAN communication DTCs may be found in control modules. There is sporadic data disruption on the CAN bus wiring behind the dashboard, between the left (T46a) and right (T46b) 46-pin CAN disconnect plugs. |
| Campaign Circula | 2017-12-05. Service bulletin. EQUIPMENT:ELECTRICAL; ELECTRICAL SYSTEM:SOFTWARE. In some vehicles, corrosion can form in the differential pressure sensor, causing the Malfunction Indicator Light (MIL) to come on. If the MIL is on because of this issue, a vehicle will not pass an IM (emissions) inspection. In some vehicles under certain driving conditions, the MIL may come on due to an issue with the Engine Control Module (ECM) software. If the MIL is on because of this issue, the vehicle will not pass an IM (emissions) inspection. Update ECM software and/or replace the differential pressure sensor. |
| A941323 2033675- | 2017-12-05. Service bulletin. ELECTRICAL SYSTEM:WIRING: REAR COMPARTMENT/TRUNK; ELECTRICAL SYSTEM. Supersedes Technical Service Bulletin Group 94 number 13-17 dated May 22, 2013. DTC 03073 (Closed Rear Lid Sensor - Incorrect Signal) may be stored in the comfort system central control module, J393 (address word 46). In order for the vehicle to receive a proper rear lid status signal when the lid is operated, the paddle switches on the rear sill trim must contact the opposing lid latch points uniformly. When the rear lid is opened, the paddle switches change state and the comfort system central control module 2, J773, will read G525 and G526. It will then communicate to the comfort system central control module, J393. |
| 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. |
| A551331 2033675- | 2017-12-05. Service bulletin. ELECTRICAL SYSTEM:WIRING: REAR COMPARTMENT/TRUNK. DTC 03073 (Closed Rear Lid Sensor - Incorrect Signal) may be stored in the comfort system central control module, J393 (address word 46). In order for the vehicle to receive a proper rear lid status signal when the lid is operated, the paddle switches on the rear sill trim must contact the opposing lid latch points uniformly. When the rear lid is opened, the paddle switches change state and the comfort system central control module 2, J773, will read G525 and G526. It will then communicate to the comfort system central control module, J393. |
| 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. |
| A011380 2024344- | 2017-11-17. Service bulletin. ENGINE AND ENGINE COOLING; ELECTRICAL SYSTEM. Supersedes Technical Service Bulletin Group 01 number 11-19 dated February 3, 2011. MIL on. Vehicle has reduced performance (in "limp mode"). Various entries may be logged. After recognizing that the boost pressure is too low or too high, the engine control module switches to emergency operation and the engine performance is reduced via the injected fuel quantity ("limp mode"). |
| 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. |
| A941310 2029194- | 2017-11-17. Service bulletin. EXTERIOR LIGHTING; ELECTRICAL SYSTEM. Supersedes Technical Service Bulletin Group 94 number 13-03 dated February 1, 2013. Only vehicles with Xenon headlights can be affected by this condition. The customer complains the high beams do not function on one side or one of the low beams flickers intermittently. In addition to this, an "Adaptive Headlight Defective" warning can be present in the cluster if the vehicle has the Prestige trim level. One of the following DTCs are set in the vehicle electrical system control module, J519 (09), or in the headlamp range control module, J431 (55), depending on the trim level of the vehicle. Vehicles with the Premium Plus option package can have the DTC set in the J519 (09) module. Vehicles with the Prestige option package can have the DTC set in the J431 (55) module. One or more of the connectors inside the headlamp housing are disconnected fully or partially from the factory. |
| 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. |
| A911517 2042013- | 2017-11-17. Service bulletin. ELECTRICAL SYSTEM: INSTRUMENT CLUSTER/PANEL. While using Audi connect, the customer cannot access the online destination search and/or the Google Earth navigation view. ?This service is currently unavailable. Please try again later" message appears in the MMI. The customer may also see an error message in the myAudi portal indicating that one or multiple licenses are expired and must be renewed. Replacing the SIM card or MMI hardware or performing the SVM recovery activation will not remedy the concern. |
| 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. |
| A911521 2039476- | 2017-11-17. Service bulletin. ELECTRICAL SYSTEM:SOFTWARE. Supersedes Technical Service Bulletin Group 91 number 15-06 dated July 28, 2015. The customer complains that the Audi connect online service in their 2011-2013 A8, 2012-2013 Q7, or 2013 A4, A5, A5 cabriolet, or Q5 vehicle only reaches 2G service. This bulletin applies only to model year 2011-2013 A8, 2012-2013 Q7, and 2013 A4, A5, A5 cabriolet, and 2013 Q5 vehicles. For 2012-2013 A6 and A7 vehicles see TSB 2039515. This bulletin does not apply to model year 2014 and newer. Starting with model year 2014, the new telephone module was installed in production. The model year 2014 A8 is not included in this repair. Model year 2014 was the last year before the A8 product improvement and ElsaPro may classify these vehicles as model year 2013 because these vehicles are the same from a technical and design standpoint. But unlike the model year 2013 vehicles, the model year 14 vehicles already have the updated telephone module in the MMI. Recently, T-Mobile (the service provider for Audi connect) has repurposed some of the GSM spectrum (3G on 2100Mhz band) to maximize 4G LTE coverage in certain metropolitan areas. Devices that do not support 3G service on the 1900MHZ band (including MMI main units of the vehicles to which this bulletin applies) will only receive 2G service when the switch is completed. The change currently only affects the markets listed above, but will affect other markets in coming years. This bulletin will be updated to include these markets as changes occur. |
| A911529 2013422- | 2017-11-17. Service bulletin. ELECTRICAL SYSTEM. Supersedes Technical Service Bulletin Group 91 number 13-04 dated September 11, 2013. The Bluetooth® telephone cannot be connected to the vehicle?s Infotainment system. Certain restrictions are present when a Bluetooth device is connected to the vehicle. The restrictions vary depending on the vehicle system present. |
| 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. |
| A231537 2040752- | 2017-11-17. Service bulletin. ELECTRICAL SYSTEM; FUEL SYSTEM, GASOLINE. Supersedes Technical Service Bulletin Group 23 number 15-36 dated July 17, 2015. The MIL is on. Vehicle either runs roughly or does not start. DTCs are stored in the ECM. Metallic particles in the high pressure fuel pump may cause the condition. |
| 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. |
| 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. |
| A011258 2031458- | 2017-11-08. Service bulletin. ELECTRICAL SYSTEM. MIL on, with one or more DTCs stored in the 01 (Engine Control Module). Under extreme driving conditions, such as a driving profile of mainly short distance (stop and go) driving high crankcase pressure can lead to the above described DTC codes. By changing the crankcase pressure valve to a lower operating pressure this condition can be improved and eliminate the mentioned possible DTC codes. Along with the crankcase pressure being lowered, a new ECM software level is required to compensate for new crankcase pressure. |
| A941296 2027773- | 2017-11-08. Service bulletin. EXTERIOR LIGHTING:HEADLIGHTS; EQUIPMENT; ELECTRICAL SYSTEM. Supersedes Technical Service Bulletin Group 94 number 12-69 dated March 15, 2012. Part or all of the daytime running lights do not work on vehicles with LED DRLs. For vehicles with halogen DRLs, please reference 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. |
| A941298 2028277- | 2017-11-08. Service bulletin. ELECTRICAL SYSTEM; EXTERIOR LIGHTING:HEADLIGHTS; EQUIPMENT. Supersedes Technical Service Bulletin Group 94 number 12-91 dated October 24, 2012. Considerable moisture present in headlamp. The moisture disappears only after extended drives (greater than 10 minutes). No external damage to headlamp which could introduce moisture. Humid air settles on the inside of the glass, causing moisture to appear on the inside of the headlamp lens. Because of the headlamp circulation system, outside air is allowed to flow through the headlamps. The open, water-protected ventilation system (needed for pressure compensation) creates different ? climate zones? inside the headlamp, where the lens is either warmed up by the light or cooled down by passing air. When high air humidity and temperature differences exist between the inside of the headlamps and the outside, condensation can form on the inside of the lens, especially in cold and wet weather. The moisture in the headlamps can be compared with condensation on the windshield, which is cleared by the "defroster vent". This moisture buildup can happen for example: after a car wash, after steam cleaning of the engine or the front end, or after overnight temperature changes. This condition is more easily visible with headlamps made from clear glass. The moisture is an optical condition which does not affect the headlamp function (light performance) and does not lead to corrosion nor does it lead to damage of the internal headlamp parts. This condition is common to all exterior vehicle lights, and can occur on every headlamp, fog lamp, or rear lamp. |
| A941299 2029194- | 2017-11-08. Service bulletin. EXTERIOR LIGHTING; ELECTRICAL SYSTEM. Supersedes Technical Service Bulletin Group 94 number 12-74 dated April 23, 2012 . The customer complains the high beams do not function on one side or one of the low beams flickers intermittently. In addition to this, an ? Adaptive Headlight Defective? warning can be present in the cluster if the vehicle has the Prestige trim level. DTCs are set in the 09 ? Central Electric Control Unit or in the 55 ? Headlamp Range Control Unit depending on the trim level of the vehicle. Vehicles with the Premium Plus option package can have the DTC set in the 09 module. Vehicles with the Prestige option package can have the DTC set in the 55 module. One or more of the connectors inside the headlamp housing are disconnected fully or partially from the factory. |
| A271215 2031145- | 2017-11-08. Service bulletin. ELECTRICAL SYSTEM. Supersedes Technical Service Bulletin Group 27 number 12-14 dated October 12, 2012. Complaints are reported by the customer regarding electrical features and functions in the vehicle. One or more warning lights on in cluster. The DIS or other displays in cluster are blank. MMI does not function. Windows do not function. LED indicators in various buttons inside the vehicle do not light up. The voltage regulator on the alternator can sporadically fail causing the electrical system to experience too high of voltage. As a result, the affected vehicle electronic components go in to high voltage protection and deactivate sensitive displays and indicators to prevent electrical damage. When an over voltage condition occurs the vehicle electronics and alternator are protected, thus there is no need to replace the entire alternator assembly. |
