| 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. |
| 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. |

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. |
| 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. |
| 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. |
| A011259 2027732- | 2017-11-08. Service bulletin. ELECTRICAL SYSTEM:SOFTWARE. Supersedes Technical Service Bulletin Group 24 number 12-44 dated September 17, 2012. MIL on. DTC P0456 (very small EVAP leak) stored in ECM. No leaks found in the EVAP system. Software update needed. |

| A431211 2018765- | 2017-11-08. Service bulletin. ELECTRICAL SYSTEM; ENGINE AND ENGINE COOLING. Supersedes Technical Service Bulletin Group 43 number 12-08 dated February 2, 2012. The self-leveling system cannot be adjusted any more with the MMI. The compressor for the self-leveling system continues to run after switching off the engine and locking the vehicle. DTCs may be stored. Because of poor performance or failure of the compressor for air suspension, the vehicle position cannot be adjusted. As a safeguard, the control module will lower the vehicle to the lowest position and illuminate the warning light. Drivability is not affected. |
| A461226 2031135- | 2017-11-08. Service bulletin. LANE DEPARTURE; PARKING BRAKE; ELECTRICAL SYSTEM. The customer may state the yellow warning for electric parking brake (EPB) appeared once in the instrument cluster, but the warning turned OFF after cycling the ignition and there have been no additional occurrences. The customer may state the adaptive cruise control (ACC) was inoperative once, but resumed operating properly after cycling the ignition and there have been no additional occurrences. DTC is stored in the EPB module. Internal code Param_InterFaultID 24 or 25 may be in the extended environmental conditions. The concern is due to a software glitch in the EPB control module. Concerns related to this software glitch can only occur once. Replacing the EPB module may cause an additional occurrence. |
