Service bulletins for the 2003 Audi A6

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.

G12++ coolant (for service available) has been introduced in MY 2005 for all engines. G13 has been introduced in MY 2008 as factory filling and service.
741312 2004327-42017-11-03. Service bulletin. STRUCTURE; EQUIPMENT. Supersedes Technical Service Bulletin Group 70 number 08-39 dated December 4, 2008. Leather upholstery is dirty or stained.
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.
A901341 2010353-2017-10-31. Service bulletin. EQUIPMENT ADAPTIVE/MOBILITY. Supersedes Technical Service Bulletin Group 90 number 10-14 dated August 10, 2010.

As a result, the socket can become inoperative when used as a power outlet.
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.
A101310 2018288-2017-10-31. Service bulletin. ENGINE AND ENGINE COOLING. Supersedes Technical Service Bulletin Group 10 number 10-02 dated September 14, 2010. 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.

Parts of the speakers (such as the brackets, cables, or covers) or parts of the interior fittings (such as door covers, rear shelf, facings, or covers) can vibrate at certain frequencies, causing noises. The radio tuner or other control modules may be affected by electromagnetic interference from aftermarket electronic devices.
A011507 2028344-2017-10-25. Service bulletin. ENGINE AND ENGINE COOLING. Supersedes Technical Service Bulletin Group 01 number 13-69 dated February 14, 2013.

Sporadic fault memory entries are stored in various control modules. Contacts may be widened (over 0.63 mm) if incorrect pins or incorrect methods for current flow tests are used. Either action may cause intermittent electrical connections, which can cause sporadic DTCs to be stored in various control modules.
A941565 2012749-2017-10-21. Service bulletin. EXTERIOR LIGHTING:HEADLIGHTS. Supersedes Technical Service Bulletin Group 94 number 12-92 dated October 24, 2012.

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.
A171557 2010043-2017-10-21. Service bulletin. ENGINE AND ENGINE COOLING. Supersedes Technical Service Bulletin Group 17 number 13-35 dated January 9, 2013. This bulletin lists engine oils that meet Audi oil quality standards (VW 501 01, 502 00, 505 00, 505 01, and 504 00/507 00).

Prior to engine replacement, any debris lodged in transferred assemblies must be removed. If the 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 metal debris pieces are not removed prior to the installation and operation of the replacement engine, they could be drawn into the combustion chamber, which can cause a knocking noise and subsequent serious engine damage.
