Although the correct amount of oil was added to the engine during an oil change service, a check of the oil level shows that the oil level is not okay. When an unapproved aftermarket speed-filling device is used to add oil to the engine, the increased oil flow rate may force oil into the intake manifold or combustion chamber, creating the potential for engine damage. |
| A741420 2035757- | 2017-11-08. Service bulletin. EQUIPMENT:ELECTRICAL; SEATS. Supersedes Technical Service Bulletin Group 74 number 14-17 dated February 21, 2014. Customer may complain that the seat pneumatics (side bolsters and lumbar support) actuate without any input from the customer. This condition can occur when the vehicle is driven at high altitudes or when the outside temperature fluctuates. DTCs may be present in the front seat pneumatics control modules, J873 and J872 (address words 88 and 89) or in the rear seat pneumatics control modules (in certain A8 models only), J875 and J874 (address words 8A and 8D). No leak is present. There is a software issue in the seat pneumatics control modules that causes the seat pneumatics to automatically actuate in high altitudes (change in air pressure) or in fluctuating temperatures in order to maintain pressure. |
| A201434 2035073- | 2017-11-08. Service bulletin. EQUIPMENT:ELECTRICAL; ENGINE AND ENGINE COOLING. Supersedes Technical Service Bulletin Group 20 number 14-32 dated March 21, 2014. The MIL is on.

| 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. |
| A911436 2027903- | 2017-11-08. Service bulletin. ELECTRICAL SYSTEM:SOFTWARE. Supersedes Technical Service Bulletin Group 91 number 12-55 dated August 13, 2012.

| A901448 2030903- | 2017-11-08. Service bulletin. ELECTRICAL SYSTEM. Supersedes Technical Service Bulletin Group 90 number 12-35 dated October 1, 2012. Customer complains that when the vehicle is driven, various warning lights illuminate, sometimes with restricted functions in the electrical system. The complaint occurs with another complaint regarding the MMI 3G+ infotainment system. After an ignition cycle, the condition is gone and therefore, it may not be reproducible. Sporadic DTCs may be present for communication errors, restricted functions, or missing/incorrect messages. |
| A871449 2020124- | 2017-11-08. Service bulletin. EQUIPMENT:APPLIANCE:AIR CONDITIONER. Supersedes Technical Service Bulletin Group 87 number 13-44 dated August 26, 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 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. |
| A851421 2037052- | 2017-11-08. Service bulletin. EQUIPMENT:APPLIANCE:AIR CONDITIONER. There is no airflow from the outer vents. Noises may be heard from the side of the dash during operation. DTCs are stored in the air conditioning control module. The mechanical stop for vent linkage is broken, allowing for the linkage to extend past intended range of operation. |
| A461478 2036688- | 2017-11-08. Service bulletin. ELECTRICAL SYSTEM. Customer may report that the vehicle does not start due to a discharged battery. DTC U101100 (supply voltage too low) is stored in the gateway, J533 (address word 19), and/or the electronic parking brake (EPB) control module. According to the test plan "19-Read Data Bus Keep-Awake Manager", the EPB control module kept the data bus active for prolonged periods of time. The EPB switch appears to be permanently operating (applying or releasing the parking brake) due to an internal mechanical issue or because it is jammed or blocked by debris or by a foreign object. |
| A441449 2022563- | 2017-11-08. Service bulletin. SUSPENSION. Supersedes Technical Service Bulletin Group 44 number 13-44 dated November 21, 2013. Customer feels vibration in the seat, vehicle floor, footwell, pedals, or steering wheel. This condition does not lead to any handling concerns or loss of vehicle control. The customer feels the vibration while driving at highway speeds from 55 - 80 mph (88 - 128 km/h). This bulletin is not applicable if this vehicle has a Repair Authorization on this topic. If an applicable Repair Authorization is not followed, the claim will not be paid. The vibrations felt by the customer could be a result of the harmonic vibrations caused by the radial force variation (RFV) of the tires or an imbalance of the wheel and tire assembly. Tires with higher mileage and/or wear should be inspected to determine the best correction for the issue (repair or replacement). Tire life and condition should be determined prior to starting any diagnosis or repair for a vibration. |
| A271424 2025360- | 2017-11-08. Service bulletin. ELECTRICAL SYSTEM; ELECTRICAL SYSTEM:12V/24V/48V BATTERY. Supersedes Technical Service Bulletin Group 27 number 12-12 dated February 28, 2012. Customer may report that the vehicle does not start due to a discharged battery. The vehicle has either a battery diagnostic management control module or a battery energy management control module. This TSB provides basic diagnosis steps for discharged batteries, general tips for working with batteries, and system verification steps to ensure that the vehicle is configured correctly. |
| 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. |
