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.

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.
