| A441346 2010334- | 2017-10-31. Service bulletin. WHEELS:LUGS/NUTS/BOLTS/STUDS; WHEELS. Supersedes Technical Service Bulletin Group 44 number 12-32 dated August 2, 2012. Wheel bolt requires torque adjustment. Torque sticks, torque extension bars, and impact guns/wrenches are not approved by Audi of America, Inc., and should not be used to apply torque to wheel bolts. Always use a calibrated torque wrench to attain the correct wheel bolt torque and follow the proper wheel tightening procedure as outlined in Elsa. Proper use of a calibrated torque wrench ensures that all wheel bolts are tightened equally and reduces the chances of repeat repairs. Using methods other than a calibrated torque wrench to attain correct wheel bolt torque may lead to problems. |

| A611321 2010342- | 2017-10-31. Service bulletin. ELECTRICAL SYSTEM. Supersedes Technical Service Bulletin Group 61 number 11-14 dated August 16, 2011. Convertible top exterior cloth appears soiled. The convertible top is made of durable fabric that has been treated at the factory with a compound that helps repel dirt and water. With proper care, the cloth will retain its function and proper appearance for a long time. It is normal, however, for the fabric to change color somewhat as it ages. This is particularly true of lighter-color tops. The cloth tension changes when the top is opened, which can cause kinks. When the top is closed, the kinks improve after a short time. However, these material-related kinks can never be completely avoided. In addition, dirt and dust can deposit in the kinks. If these dirt and dust deposits are not properly removed in a car wash, they can contribute to poor appearance |
| A571394 2035367- | 2017-10-31. Service bulletin. EQUIPMENT. Various features in the rear passenger compartment are inoperative. Some features may include power rear windows, rear climate control operating unit, rear sunroof panel, rear reading lamps, rear cigarette lighters, etc. By design, many electronically-controlled features in the rear passenger compartment, in addition to the power rear windows, are deactivated if the child lock in the driver's door is activated. |

Prior to engine replacement, any debris lodged in transferred assemblies must be removed. If the vehicle's engine experienced a serious mechanical problem, it is possible that small pieces of metal debris resulting from the mechanical problem may have become deposited in the intake manifold, air intake hoses, exhaust manifolds, exhaust down-pipes, turbocharger, supercharger, and/or intercooler. If these pieces are not removed prior to the installation and operation of the replacement engine, the pieces may be drawn into the combustion chamber, which can cause a knocking noise and subsequent serious engine damage. |

| 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. |
