Service bulletins for the 2004 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.

209 on file from NHTSA, as of 2026-10-19.

Accessories Oper2017-12-05. Service bulletin. EQUIPMENT. This is an advance notice for Audi of America employees. This notice contains information for the accessories operations technical bulletin.
A001470 2039206-2017-12-05. Service bulletin. ELECTRICAL SYSTEM. High quality media files (video and sound) are now integrated into technical service bulletins on a case-by-case basis. Media files can now be viewed on any smartphone or tablet. Audi of America has started to host its TSB videos outside of ElsaPro. Doing so provides higher-quality videos, more reliable access to the videos, and the ability to view the videos on different devices.
A481462 2017266-2017-12-05. Service bulletin. ELECTRICAL SYSTEM. Supersedes Technical Service Bulletin Group 48 number 14-59 dated June 2, 2014. Electrically-adjustable steering column adjustment is restricted and does not adjust vertically. Incorrect operation of Easy Entry is not the cause. It is unlikely that external forces have led to the loss of the stored end positions of the adjustment movement. Seat adjustments can be used to maintain the 10-inch minimum recommended distance from the steering wheel in case of airbag deployment. The axial adjustment is still functional during this condition.
A641436 2020552-2017-12-05. Service bulletin. VISIBILITY:WINDSHIELD. Windshield is streaked, has a snakeskin appearance, or its surface feels rough. Residue from industrial fallout as well as normal road dirt and grime may accumulate on windshield.
A441455 2010334-2017-12-05. Service bulletin. WHEELS. Supersedes Technical Service Bulletin Group 44 number 13-46 dated December 9, 2013. Wheel bolt requires torque adjustment.
2013_06_ATU Audi2017-12-05. Service bulletin. EQUIPMENT:OTHER:OWNERS/SERVICE/OTHER MANUAL. This document contains information on the Audi side assist update.
A461353 2034181-2017-12-05. Service bulletin. SERVICE BRAKES. Customer may report hearing brake noise from front or rear brakes. Customers may describe these noises as a squeal, squeak, grinding, groaning, thumping, or creaking.
A481349 2015819-2017-12-05. Service bulletin. STEERING:ELECTRIC POWER ASSIST SYSTEM. Supersedes Technical Service Bulletin Group 48 number 13-43 dated April 19, 2013. The customer may report that the Easy Entry function of the power adjustable steering column intermittently does not work.
A481351 2017266-2017-12-05. Service bulletin. STEERING. Supersedes Technical Service Bulletin Group 48 number 10-09 dated August 13, 2010. Electric steering column adjustment is restricted or does not work at all. Incorrect operation of Easy Entry is not the cause. It is unlikely that external forces have led to the loss of the stored end positions of the adjustment movement. See TSB 2015819, 48 Easy Entry function of the power adjustable steering column intermittently does not work, for more information. The seat adjustments can be used to maintain the 10-inch minimum recommended distance from the steering wheel in case of airbag deployment. The steering column may be under tension due to unfavorable tolerances of the steering column and module cross carrier. As a result, the current draw of the regulator motors is above specification, so the electric steering column adjustment fails.
A641329 2020552-2017-12-05. Service bulletin. VISIBILITY:WINDSHIELD. Windshield is streaked, has a snakeskin appearance, or its surface feels rough. Residue from industrial fallout as well as normal road dirt and grime may accumulate on windshield.
A871344 2020124-2017-12-05. Service bulletin. EQUIPMENT:APPLIANCE:AIR CONDITIONER. Supersedes Technical Service Bulletin Group 87 number 13-43 dated July 12, 2013. Air conditioning is inoperative. The HVAC blower functions normally. 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. Battery discharged; however, when charged, there is no bus silence when vehicle ignition is off. 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.
A911302 2018187-2017-12-05. Service bulletin. EQUIPMENT:ELECTRICAL:RADIO/TAPE DECK/CD ETC.. Supersedes Technical Service Bulletin Group 91 number 11-20 dated October 21, 2011. Customer may report that cracking, grinding, rattling, humming, whining, or similar interference is coming from one or more speakers. 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.
A961367 2019260-2017-12-05. Service bulletin. EQUIPMENT:ELECTRICAL. Supersedes Technical Service Bulletin Group 96 number 12-37 dated June 11, 2012. The customer may report that the handheld transmitter cannot be programmed to the garage door opener control module, J530. The customer's door opener system may not be compatible with J530. The battery in the handheld transmitter may be too weak for a good signal. The battery charge may be sufficient to operate the garage door opener, but not enough to program the remote transmitter to the vehicle system. In A4 Model Years 2005 - 2006 and A3 Model Year 2009, the actual location of the garage door opener control module differs from the location shown in the owner's manual (opposite side of front bumper). The customer may misunderstand the programming procedure, particularly if the customer's HomeLink® opener system is using an alternate code. The handheld transmitter's programming function may become inoperative, or the transmitter is too far away from J530. Interference prevents the communication between handheld transmitter and J530. If the vehicle flashes during the programming of a handheld transmitter, this does not necessarily indicate that the programming was successful; it only indicates that the vehicle has recognized and saved a signal.
A871343 2020124-2017-12-05. Service bulletin. EQUIPMENT:APPLIANCE:AIR CONDITIONER. Supersedes Technical Service Bulletin Group 87 number 13-42 dated June 11, 2013. Air conditioning is inoperative.

A461347 2034387-2017-12-05. Service bulletin. ELECTRICAL SYSTEM; PARKING BRAKE. Customer may report sporadically hearing the parking brake being actuated after the vehicle has been switched off. If the customer does not identify the sound as the sound of the parking brake being actuated, he or she may simply complain of hearing noises from the rear brakes. Ignition is switched off. Steering is locked. Park is selected. Parking brake is not engaged. If the electro-mechanical parking brake is not operated for some time, the free play between brake pads and brake discs increases because of normal brake pad wear. The parking brake control unit performs an automatic correction about every 621 miles (1,000 km). On A8 models, the brake pad thickness is also calculated.
A571382 2017082-2017-11-17. Service bulletin. LATCHES/LOCKS/LINKAGES; EQUIPMENT:ELECTRICAL. Supersedes Technical Service Bulletin Group 57 number 11-55 dated August 22, 2011. Central locking via remote control does not work either sporadically or permanently. The locks can still be operated manually. Missing synchronization between the remote control key and vehicle because the battery has been disconnected or the battery of the remote control has been replaced. If other senders operate in the same frequency range (mobile phones, TV stations, wireless headphones, baby monitors, other vehicle remote controls, etc.), the remote control key may have been temporarily switched off because a clear identification of the remote control key is not possible. This is necessary to prevent an unintentional unlocking of the vehicle by other unrelated senders.
A481343 2015819-2017-11-17. Service bulletin. STEERING:ELECTRIC POWER ASSIST SYSTEM. Supersedes Technical Service Bulletin Group 48 number 11-15 dated January 10, 2011. The customer may report that the Easy Entry function of the power adjustable steering column intermittently does not work.
A461335 2017130-2017-11-17. Service bulletin. SERVICE BRAKES. Supersedes Technical Service Bulletin Group 46 number 11-16 dated December 9, 2011. Customer complains of brake squeal.
A431314 2018765-2017-11-17. Service bulletin. SUSPENSION:REAR:SPRINGS:AIR SUSPENSION SYSTEM; SUSPENSION:FRONT:SPRINGS:AIR SUSPENSION SYSTEM. Supersedes Technical Service Bulletin Group 43 number 12-11 dated October 29, 2012. The self-leveling system can no longer be adjusted with the MMI. The compressor for the self-leveling system continues to run after the engine has been switched off and the vehicle has been locked. DTCs may be stored in the level control system module, J197 (address word 34). Because of poor performance or failure of the air suspension compressor, the vehicle ride height cannot be adjusted. As a safeguard, the control module will lower the vehicle to the lowest position and illuminate the warning light. Drivability is not affected.
A001348 2002047-2017-11-17. Service bulletin. EQUIPMENT:OTHER:OWNERS/SERVICE/OTHER MANUAL. Supersedes Technical Service Bulletin Group 00 number 11-19 dated April 8, 2011. This TSB contains information on technician preparation when calling the Audi Technical Assistance Center
A191335 2025303-2017-11-17. Service bulletin. ENGINE AND ENGINE COOLING. Supersedes Technical Service Bulletin Group 19 number 11-19 dated February 10, 2011. Discontinuation and mixing of Audi-approved engine coolants. G11, G12, and G12+ coolants have been replaced by an improved version. 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.
A571385 2017082-2017-11-17. Service bulletin. ELECTRICAL SYSTEM; LATCHES/LOCKS/LINKAGES:DOORS:LATCH. Supersedes Technical Service Bulletin Group 57 number 13-82 dated February 5, 2013. Central locking via remote control does not work either sporadically or permanently. The locks can still be operated manually.
