| A961368 2029384- | 2017-12-05. Service bulletin. EQUIPMENT:ELECTRICAL. Supersedes Technical Service Bulletin Group 96 number 13-64 dated June 20, 2013. 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 functions. 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. No DTCs are stored in any control units. At the workshop, the Homelink system can be programmed to the workshop garage door successfully. No trouble is found. 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. |

| 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. |
| A871343 2020124- | 2017-12-05. Service bulletin. EQUIPMENT:APPLIANCE:AIR CONDITIONER. Supersedes Technical Service Bulletin Group 87 number 13-42 dated June 11, 2013. 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. |
| A481346 2021191- | 2017-12-05. Service bulletin. STEERING. Supersedes Technical Service Bulletin Group 40 number 09-06 dated August 3, 2009. Customer hears squeaking noises when turning or maneuvering the steering wheel. The folds of the outer CV joint rubber boots can touch each other when the steering wheel is turned. |
| 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. |
| A371309 2028715- | 2017-12-05. Service bulletin. POWER TRAIN. Supersedes Technical Service Bulletin Group 37 number 12-40 dated February 28, 2012. Rough gear changes, both when accelerating and when slowing down. There is a rough driving power disruption that occurs sporadically and lasts for less than a second. After a mechatronics, torque converter, or complete gearbox replacement, the clutches must be adapted to the new component. This requires a gradual move of the clutch linings toward the optimal operating points in the most diverse load conditions. As a result, sporadic driving power disruptions lasting for less than a second or reduced shift comfort are possible over the first 500 miles. This is normal, and these issues will decrease over time. The issues can also occur if the adaptation values of the gearbox were deleted. |
| A191344 2033491- | 2017-12-05. Service bulletin. ENGINE AND ENGINE COOLING. Supersedes Technical Service Bulletin Group 19 number 13-42 dated July 11, 2013. Customer may report coolant leaking from the engine area. The leak can be traced to the connection of the water pump and the hose leading to the heater core. The seal ring is not the cause of the leak. |
| A191342 2033491- | 2017-12-05. Service bulletin. ENGINE AND ENGINE COOLING. Supersedes Technical Service Bulletin Group 19 number 13-40 dated June 17, 2013. Customer may report coolant leaking from the engine area. The leak can be traced to the connection of the water pump and the hose leading to the heater core.

| A571382 2017082- | 2017-11-17. Service bulletin. LATCHES/LOCKS/LINKAGES; EQUIPMENT:ELECTRICAL. Supersedes Technical Service Bulletin Group 57 number 11-55 dated August 22, 2011. 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. |
| A441336 2022563- | 2017-11-17. Service bulletin. SUSPENSION. Supersedes Technical Service Bulletin Group 44 number 13-35 dated January 18, 2013. Customer feels vibration from 55 - 80 mph (88 - 128 km/h) in the seat, vehicle floor, footwell, pedals, or steering wheel. This condition does not result in any handling concerns or loss of vehicle control. |
| A171336 2030197- | 2017-11-17. Service bulletin. ENGINE AND ENGINE COOLING. Supersedes Technical Service Bulletin Group 17 number 12-34 dated December 12, 2012. Customer complains of excessive oil consumption. In order to provide effective lubrication and cooling of internal engine components, all internal combustion engines consume a certain amount of engine oil. Oil consumption varies from engine to engine and may change significantly over the life of the engine. Typically, engines with specified break-in periods consume more oil during the break-in period, and the oil consumption will stabilize after the break-in period. Refer to the Owner's Manual for specific break-in procedures. Under normal conditions, the rate of oil consumption depends on the quality and viscosity of the oil, the RPM at which the engine is operated, the ambient temperature, and road conditions. Additional factors are the amount of oil dilution from water condensation or fuel residue and the oxidation level of the oil. Under certain driving conditions, internal engine pressure conditions in the 3.0 TFSI engine can negatively influence the rate of oil consumption. This can occur while the vehicle is operated in city driving conditions, for example: stop and go traffic with extended idle periods. |
| A011369 2028344- | 2017-11-17. Service bulletin. ENGINE AND ENGINE COOLING:EXHAUST SYSTEM; ENGINE AND ENGINE COOLING. Supersedes Technical Service Bulletin Group 01 number 12-57 dated October 29, 2012. Noises/inconsistent engine operation after cold start during the catalyst heating phase. The customer may interpret this engine roughness as misfiring. To comply with the legal requirements on exhaust gas emissions according to the LEV-1 and LEV-2 standards, a high exhaust gas quality must be ensured. The necessary catalyst only operates at a temperature over 300°C (572°F). To achieve this, the catalyst is heated up. The catalyst heating phase is achieved by a late ignition angles and by introducing additional fresh air to the exhaust valves (secondary air system). Late ignition angles make sure that the exhaust gas from the cylinders has a higher temperature. This exhaust gas includes fuel that is un-burnt, and was deliberately injected into great quantities. The secondary air system adds fresh air to the exhaust gas as it leaves the cylinder and the extra fuel is burnt. As a result, the temperatures of the exhaust gas and of the catalyst increase quickly. The afterburning in the exhaust manifold before the catalyst changes the sound characteristic of the engine. This heating-up of the catalyst, including afterburning, is normal and has no effect on the service life of the engine. During this catalyst heating phase, the engine has increased idle speed, may have increased vibrations, and has a different sound characteristic. Depending on conditions, the time of the catalyst heating phase varies. |
| A481343 2015819- | 2017-11-17. Service bulletin. STEERING:ELECTRIC POWER ASSIST SYSTEM. Supersedes Technical Service Bulletin Group 48 number 11-15 dated January 10, 2011. The customer may report that the Easy Entry function of the power adjustable steering column intermittently does not work. |
