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.
A571516 2024111-2017-11-17. Service bulletin. ELECTRICAL SYSTEM:SOFTWARE. Supersedes Technical Service Bulletin Group 69 number 12-22 dated February 13, 2012. 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.

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 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.
A961365 2033943-2017-11-17. Service bulletin. ELECTRICAL SYSTEM. Supersedes Technical Service Bulletin Group 96 number 13-60 dated May 23, 2013. Audi Lane Change Assistant (Side Assist) deactivates or is sporadically inoperative when the vehicle is driven in slow-moving, stop-and-go traffic or when it is driven for long periods of time on open roads that have no traffic. A warning message is seen in the instrument cluster driver information system stating ?Audi side assist unavailable: Sensors blocked?. The system is able to be activated approximately ten minutes after the traffic condition is removed, or after an ignition cycle. Audi Lane Change Assistant can be activated without issue. No obstructions can be found. DTCs are stored in the Lane Change Assistance control module. No damage is found to the rear bumper area, inside and outside (If any damage is found, it is not covered under warranty). The control unit mounting brackets are securely fastened to the lower rear bumper, and they are not lose or broken. If a loose bracket is found, repair as necessary using the ElsaWeb Repair Manual. Submit a separate warranty claim, as this TSB does not cover this repair. The software of the Lane Change Assistance control module can deactivate the Audi Side Assist system in certain normal driving conditions because the nature of these driving conditions make it difficult for the Audi Side Assist system to track vehicles.

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.
A961243 2031095-2017-11-08. Service bulletin. ELECTRICAL SYSTEM; ENGINE AND ENGINE COOLING. Audi Side Assist deactivates itself immediately following the engine starting. The DTC entry "Control unit 2 for lane changing assistant - restricted function because of low voltage, sporadic" is logged in the control unit ?3C ? Lane Change Assistant?. The control unit ?3C ? Lane Change Assistant? checks voltage after each engine on cycle and during this check the voltage can be incorrectly reported which causes the DTC to set.
Dealer Letter -2017-11-08. Service bulletin. STEERING; ELECTRICAL SYSTEM. This communication is to inform you of Update 48K4. On Audi vehicles with electromechanical power steering manufactured within a specific period, an irregularity detected by the diagnosis function can result in an implausible status immediately after the engine is started. This causes the warning lamp for the electromechanical power steering to light up. There is no loss of steering functionality. Update the power steering control module (J500) software.
A021202 2032094-2017-11-08. Service bulletin. ELECTRICAL SYSTEM; POWER TRAIN. Customer may report transmission warning light comes on. No drivability/starting concerns. GFF scan shows fault code- P060300 (Control Module Malfunctioning, Sporadic), stored in the Transmission control module (02).

The plastic stop on the adapter of the fresh air blower motor is damaged in production. As a result, the blower moves within its housing. This allows the blower impeller to make contact with the blower motor housing.
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.
A911270 2032240-2017-11-08. Service bulletin. EQUIPMENT; ELECTRICAL SYSTEM; EQUIPMENT:OTHER:OWNERS/SERVICE/OTHER MANUAL. The Google Earth map will not load.
