Service bulletins for the 2009 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.

TRMDMV_PR_Audi2022-08-04. Service bulletin. EQUIPMENT; AIR BAGS. In conjunction with the Georgia Department of Revenue - Motor Vehicle Division and Department of Driver Services, Audi sent Takata airbag recall reminder notices to approximately 565 Audi owners in the State of Puerto Rico on July 25, 2022.
A4822342065978_22022-08-03. Service bulletin. EQUIPMENT; EQUIPMENT ADAPTIVE/MOBILITY; STEERING:STEERING WHEEL /HANDLE BAR:HAND HEATER/COOLER. This bulletin explains that the steering wheel may warm up while being held leading to the impression that he steering wheel isn't heating evenly.
1337203019792022-08-01. Service bulletin. ENGINE AND ENGINE COOLING. Customer complains of excessive oil consumption.
1440203383622022-08-01. Service bulletin. FUEL SYSTEM, DIESEL. Beginning with MY2009, the filler necks of various TDI clean diesel vehicles were equipped with a misfueling guard (Figure 1). The guard minimizes the likelihood that fuel other than ultra-low sulfur diesel will be put into the vehicle. The misfueling guard is designed to remain in a locked position when a nozzle with a diameter typically suited for non-diesel fuels (approximately 13/16?, or 20.6mm) is inserted, to prevent further insertion of the nozzle into the filler neck. A nozzle with a larger diameter typically suited for diesel fuel (approximately 15/16?, or 23.8mm) will unlock the misfueling guard when inserted, allowing the nozzle to be further inserted into the filler neck.

1453203812922022-08-01. Service bulletin. ENGINE AND ENGINE COOLING:ENGINE:OIL/LUBRICATION. A check with the engine oil service dipstick T40178 is necessary, but the adjustment values for the dipstick are not available in the Elsa repair manual. Because of a system change, the adjustment values for the service dipstick T40178 were removed from the repair manual.
1450203812912022-08-01. Service bulletin. ENGINE AND ENGINE COOLING:ENGINE:OIL/LUBRICATION. A check with the engine oil service dipstick T40178 is necessary, but the adjustment values for the dipstick are not available in the Elsa repair manual. Because of a system change, the adjustment values for the service dipstick T40178 were removed from the repair manual.
1449202844022022-08-01. Service bulletin. BACK OVER PREVENTION:DISPLAY FUNCTION. The customer complains of one or more of the following issues: ? When the vehicle is completely refueled, the vehicle range (?distance to empty?) that is displayed is different than the vehicle range that was displayed the last time the vehicle was completely refueled. ? The displayed vehicle range drops inconsistently. ? After the vehicle is refueled, the displayed vehicle range does not change for a long period of time. ? When the vehicle is driven on hilly roads for a long period of time, the displayed vehicle range suddenly changes by a significant amount. ? There are no DTCs related to fuel senders stored in the instrument cluster control module, J285 (address word 17). This condition does not involve or affect the accuracy of the fuel level indicator, but only the estimated distance to empty display on the on-board computer.
13462030197122022-08-01. Service bulletin. EQUIPMENT. In order to provide effective lubrication and cooling of internal engine components, all internal combustion engines consume a certain amount of engine oil. Oil consumption varies from engine to engine and may change significantly over the life of the engine. Typically, engines with specified break-in periods consume more oil during the break-in period, and the oil consumption will stabilize after the break-in period. Refer to the Owner?s Manual for specific break-in procedures.
13452030197112022-08-01. Service bulletin. SERVICE BRAKES; EQUIPMENT. In order to provide effective lubrication and cooling of internal engine components, all internal combustion engines consume a certain amount of engine oil. Oil consumption varies from engine to engine and may change significantly over the life of the engine. Typically, engines with specified break-in periods consume more oil during the break-in period, and the oil consumption will stabilize after the break-in period. Refer to the Owner?s Manual for specific break-in procedures. Under normal conditions, the rate of oil consumption depends on the quality and viscosity of the oil, the RPM at which the engine is operated, the ambient temperature, and road conditions. Additional factors are the amount of oil dilution from water condensation or fuel residue, and the oxidation level of the oil. Under certain driving conditions, internal engine pressure conditions in the 3.0 TFSI engine can negatively influence the rate of oil consumption. This can occur while the vehicle is operated in city driving conditions, for example: stop and go traffic with extended idle periods.
13392030197102022-08-01. Service bulletin. ENGINE AND ENGINE COOLING:ENGINE:OIL/LUBRICATION. Engine oil consumption - Customer complaints, 3.0T TFSI Model Year 2009 ? 2012
1338201291352022-08-01. Service bulletin. POWER TRAIN:AUTOMATIC TRANSMISSION:FLUID/LUBRICANT:FILTER/SCREEN. Engine oil service - filter cartridge replacement. When changing the oil filter and installing the new filter seal(s) in the oil filter housing, special attention is required.

Additional factors are the amount of oil dilution from water condensation or fuel residue and the oxidation level of the oil. Under certain driving conditions internal engine pressure conditions in the 3.0 TFSI engine can negatively influence the rate of oil consumption. This condition can occur while the vehicle is operated in metro driving conditions, for example: Stop and go traffic with extended idle periods.
1497203300172022-08-01. Service bulletin. EQUIPMENT:OTHER:OWNERS/SERVICE/OTHER MANUAL. Under certain driving conditions, the secondary air ports in the cylinder head can accumulate carbon over time, causing a restriction.

1490203545432022-08-01. Service bulletin. POWER TRAIN. Under certain driving conditions, the secondary air ports in the cylinder head can accumulate carbon over time, causing a restriction. The ODIS tester can identify the state of the restriction, and will request that the system is cleaned in order to prevent the MIL from illuminating.
1489203300162022-08-01. Service bulletin. POWER TRAIN. Under certain driving conditions, the secondary air ports in the cylinder head can accumulate carbon over time, causing a restriction.
1473203145852022-08-01. Service bulletin. SERVICE BRAKES. Under extreme driving conditions (such as short-distance, stop-and-go driving), high crankcase pressure can cause the DTCs to appear. The condition can be improved and the DTCs eliminated when the crankcase pressure valve is changed to a lower operating pressure and the ECM software is updated to compensate for new crankcase pressure.
