Service bulletins for the 2013 Audi A8

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

A011852 2050329_2018-04-16. Service bulletin. ELECTRICAL SYSTEM. This bulletin contains repair instructions for when the MIL is on and there are one of several DTCs stored in the ECM.

A911506 2039476-2018-04-02. Service bulletin. ELECTRICAL SYSTEM. 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 when in metropolitan areas. 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. 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.
A011685 2041120-2018-03-13. Service bulletin. ENGINE; ELECTRICAL SYSTEM. This bulletin provides information regarding a software update for DTC P042000 and/or P043000.
A011688 2040403-2018-03-13. Service bulletin. ELECTRICAL SYSTEM. This technical service bulletin instructs the reader to replace either a combi valve or vacuum solenoid valve depending on the circumstances under which DTC P244000 and/or P244200 were stored.
A0115292041097-12018-02-05. Service bulletin. ENGINE; ELECTRICAL SYSTEM. The MIL is on. Customer may report that the engine runs irregularly. DTCs are stored in the ECM. On the camshaft adjustment valve, the filter element can loosen. There is no consequential damage from loosened particles in the oil circuit. They are gathered by the oil filter.
A0115362041120-22018-02-05. Service bulletin. ELECTRICAL SYSTEM. Supersedes Technical Service Bulletin Group 01 number 15-26 dated June 30, 2015. The MIL is on. DTC P042000 and/or P043000 (Catalyst system Bank 1/2, Efficiency below threshold) is stored in the engine control module (ECM). The diagnostic limitations were too narrow.
A871569 2020124-2018-02-05. Service bulletin. ELECTRICAL SYSTEM:12V/24V/48V BATTERY; EQUIPMENT:APPLIANCE:AIR CONDITIONER. Supersedes Technical Service Bulletin Group 87 number 14-49 dated April 25, 2014. 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. 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.
A0115312033806-72018-02-05. Service bulletin. ELECTRICAL SYSTEM; ENGINE AND ENGINE COOLING. Supersedes Technical Service Bulletin Group 80 number 14-07 dated August 11, 2014. The MIL is on. Climate system heating performance is insufficient. Coolant level warning is on. Engine temperature is elevated. ?Limp Home? mode is active. Faults may be 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 as a result of coolant migration in the electrical harness, faults in 08-Heating and Air Conditioning Electronics that result from coolant migration in the electrical harness, or a faulty N82 control valve.
