A011521 2040508-2017-10-21. Service bulletin. POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE (TCM/PCM/TECM); ELECTRICAL SYSTEM:SOFTWARE. The MIL is on. DTC P046100 is stored in the ECM. DTC P046100 can be caused by miscalculations within the ECM software.
A941564 2017806-2017-10-21. Service bulletin. ELECTRICAL SYSTEM. Supersedes Technical Service Bulletin Group 94 number 15-60 dated February 12, 2015. The light bulb warning light is displayed in the instrument cluster with the following message: "Vehicle lights: malfunction". DTCs are stored in the vehicle electrical system control module. Exterior lights are functioning properly.
A911579 2038824-2017-10-21. Service bulletin. ELECTRICAL SYSTEM. Supersedes Technical Service Bulletin Group 91 number 14-69 dated November 4, 2014. The following message appears on the MMI display: "Device or cable type not supported". The AMI cable being used is a genuine Audi-branded cable with an Audi part number (see Required Parts and Tools for a list of valid part numbers). The "Device or cable type not supported" message may be displayed when an incorrect AMI cable type is connected to the MMI system. Only cables with an Audi part number (i.e., 4F0.XXX.XXX) are supported by the MMI system. Volkswagen-branded cables look similar, but are not guaranteed to work with Audi MMI systems. The label on the end of an Audi-branded cable has an Audi logo and Audi part number. Audi-branded cables have unique firmware inside the hardware that can determine which MMI system and iOS device are connected to the cable. Volkswagen cables do not have this firmware. The firmware is required to allow the system to function normally due to the different technology available in the different MMI systems and in the different iPhones and iPod Touch devices. In addition, the AMI system was designed to play the music stored locally on the connected device only. Music streaming (from Spotify or Pandora, for example) is not supported, and music stored in the cloud (on Google Play, Amazon Prime, or iTunes Match/iCloud, for example) may drop out, pause, and skip when played.
A011513 2030580-2017-10-21. Service bulletin. EQUIPMENT:ELECTRICAL; ELECTRICAL SYSTEM:STARTER ASSEMBLY. Supersedes Technical Service Bulletin Group 01 number 15-08 dated February 17, 2015. The customer complains that the vehicle sporadically cannot be started. The yellow gearbox warning light may be illuminated. DTCs P15700 and/or P170100 may be present. The remote key being used is transmitting incomplete immobilizer information to the vehicle, resulting in the condition.
A941559 2039584-2017-10-21. Service bulletin. ELECTRICAL SYSTEM. A bulb failure warning for one or several taillight functions appears in the instrument cluster, but the taillights are operating normally. The warning only occurs at very low outside temperatures. DTC entries are logged in the comfort system central control module. The transistor in the taillight is a component of the bulb failure monitor. The transistor is out of tolerance, which causes the bulb failure monitor to not see enough current consumption when outside temperatures are very low. This causes a false lamp failure warning.
PDI - 2015 A6-S62017-10-21. Service bulletin. ELECTRICAL SYSTEM:12V/24V/48V BATTERY. This document contains the Audi pre-delivery inspection checklist. All items must be completed prior to customer delivery by an Audi technician. Audi recommends using an Audi approved battery charger to prevent excessive battery discharge during inspection. It is advised to start ODIS with the engine running to enable all 5F Test Plans in GFF and also to ensure SVM sees all control units during the SVM check vehicle configuration. Refer to the Special functions tab of ODIS Diagnosis using GFF for the PDI function tests. For items marked with *, please refer to the PDI Technician Reference Document posted on ServiceNet for additional information. This document is in Spanish.

A961604 2042811-2017-10-04. Service bulletin. ELECTRICAL SYSTEM:SOFTWARE. Audi connect Gen1 and Gen2 systems: Differences and troubleshooting. The customer has a general concern related to Audi connect. Different features are included with different generations of the Audi connect system. The Audi connect Gen1 system includes all vehicles that utilize a removable plastic SIM card. The Audi connect Gen2 system includes all vehicles that utilize an embedded SIM card. The root cause of all complaints cannot be attributed to the vehicle hardware because of the backend server configurations that need to be correct in order for Audi connect to work. For most sporadic complaints, the issue typically resides with the MBB backend server or with the source data provider (Google, INRIX, etc.), and not with the vehicle. In rare cases, the mobile network operator (AT&T, T-Mobile) can be the cause of the complaint. For most static complaints, the issue can be attributed to the user account subscription or possibly the vehicle hardware.
