Service bulletins for the 2012 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.

| 37144820300075 | 2022-11-21. Service bulletin. POWER TRAIN:MANUAL TRANSMISSION:COLUMN SHIFT ASSEMBLY. Customer may report harsh shift concerns; no faults are stored and concern is reproducible |
| 133820129135 | 2022-08-01. 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. |
| 149020354543 | 2022-08-01. 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. |
| 148920330016 | 2022-08-01. Service bulletin. POWER TRAIN. Under certain driving conditions, the secondary air ports in the cylinder head can accumulate carbon over time, causing a restriction. |
| 37 13 07 2033658 | 2022-05-31. Service bulletin. POWER TRAIN. Vehicle lacks power or will not move after stop due to simultaneous depressing of the brake and accelerator pedals |
| 37 13 05 2030582 | 2022-05-31. Service bulletin. LANE DEPARTURE; POWER TRAIN:AUTOMATIC TRANSMISSION; AIR BAGS. Transmission warning light briefly comes on |
| 37 13 01 2028985 | 2022-05-31. Service bulletin. POWER TRAIN. Transmission warning message in cluster |
| 37 14 34 2028985 | 2022-05-02. Service bulletin. ELECTRICAL SYSTEM:IGNITION; POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE:SOFTWARE; UNKNOWN OR OTHER; ELECTRICAL SYSTEM: INSTRUMENT CLUSTER/PANEL. Transmission warning may appear in instrument cluster. After ignition cycle, the warning message is no longer present. The fault occurs with ATF temperature below 60o C. Check for this temperature range in the extended environmental conditions of the diagnosis protocol. This TSB only applies if the ATF level is correct and there are no leaks. |
| 37 14 30 2003658 | 2022-05-02. Service bulletin. ELECTRONIC STABILITY CONTROL (ESC):CONTROL MODULE:SOFTWARE; POWER TRAIN. This condition may be caused when the brake pedal and the accelerator pedal are depressed simultaneously. Drivers who drive with their left foot resting on the brake pedal are prone to experience this condition. With the introduction of Electronic Power Control (EPC) (no accelerator cable) to fuel injection systems, an engine RPM control feature has been incorporated into the engine electronic control system software. Customer states that the engine returns to idle speed of approximately 1,400 RPM although the accelerator is depressed, and/or the vehicle hesitates (lacks power on take-off). |
| 37 14 24 2037127 | 2022-05-02. Service bulletin. POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE (TCM/PCM/TECM); ELECTRICAL SYSTEM:SOFTWARE; POWER TRAIN; ELECTRICAL SYSTEM. A jerky accelerator response is felt when the vehicle is pulled away from a stop in reverse. Incorrect calibration of clutch program. New software in the transmission control module (TCM), J217 (address word 02) addressed the condition. |
| 37 14 22 2028985 | 2022-05-02. Service bulletin. ELECTRICAL SYSTEM:SOFTWARE; UNKNOWN OR OTHER; POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE (TCM/PCM/TECM). The fault occurs with ATF temperature below 60° C. Check for this temperature range in the extended environmental conditions of the diagnosis protocol. This TSB only applies if the ATF level is correct and there are no leaks. |
| 37 13 97 2028985 | 2022-05-02. Service bulletin. POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE (TCM/PCM/TECM); UNKNOWN OR OTHER. The fault occurs with ATF temperature below 60o C. Check for this temperature range in the extended environmental conditions of the diagnosis protocol. This TSB only applies if the ATF level is correct and there are no leaks. |
| 37 13 80 2028985 | 2022-05-02. Service bulletin. POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE (TCM/PCM/TECM); POWER TRAIN:AUTOMATIC TRANSMISSION:TORQUE CONVERTER. DTC P074100 Torque Converter Clutch Circuit Performance or Stuck Off is stored in TCM. Customer may report transmission warning lamp illuminated in instrument cluster. |
| 37 13 18 2034863 | 2022-05-02. Service bulletin. POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE (TCM/PCM/TECM). There is a reaction between the TCM and the automatic transmission fluid (ATF) in vehicles within a specific VIN range. |
| 37 13 10 2034863 | 2022-05-02. Service bulletin. POWER TRAIN. There is a reaction between the TCM and the automatic transmission fluid (ATF) in vehicles within a specific VIN range. |
| 37 13 09 2028715 | 2022-05-02. Service bulletin. ELECTRICAL SYSTEM:12V/24V/48V BATTERY; POWER TRAIN:AUTOMATIC TRANSMISSION:INTERNAL:GEARS. After a mechatronics, torque converter, or complete gearbox replacement, the clutches must be adapted to the new component. This requires a gradual move of the clutch linings toward the optimal operating points in the most diverse load conditions. As a result, sporadic driving power disruptions lasting for less than a second or reduced shift comfort are possible over the first 500 miles. This is normal, and these issues will decrease over time. The issues can also occur if the adaptation values of the gearbox were deleted. |
| 37 13 05 2030582 | 2022-05-02. Service bulletin. POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE (TCM/PCM/TECM). The entry is caused by an overly sensitive diagnosis in the transmission control module. |
| 37 13 03 2033653 | 2022-05-02. Service bulletin. POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE (TCM/PCM/TECM); ENGINE AND ENGINE COOLING:ENGINE:ENGINE CONTROL MODULE (ECU/ECM):SOFTWARE. The entry is caused by an overly sensitive diagnosis in the TCM, due to an error in the engine control module (ECM), J623, software. This error does not affect the driving characteristics. |
| 37 13 01 2028985 | 2022-05-02. Service bulletin. ELECTRICAL SYSTEM:SOFTWARE; POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE (TCM/PCM/TECM). The fault occurs with ATF temperature below 60o C. Check for this temperature range in the extended environmental conditions of the diagnosis protocol. This TSB only applies if the ATF level is correct and there are no leaks. |
| A3720012039650_2 | 2020-08-06. Service bulletin. POWER TRAIN:TRANSFER CASE (4-WHEEL DRIVE); POWER TRAIN:AUTOMATIC TRANSMISSION. This bulletin contains instructions for addressing a leak from the transmission oil pan gasket or transfer case. |
| A301519 2019850- | 2018-02-05. Service bulletin. EQUIPMENT; EQUIPMENT:OTHER:OWNERS/SERVICE/OTHER MANUAL; POWER TRAIN. Supersedes Technical Service Bulletin Group 30 number 11-10 dated December 2, 2011. Clutch is not operating properly. Clutch has a burnt smell. Clutch pedal does not fully return to starting position. Incorrect shifting, the revolutions of clutch plate and engine input shaft differ too much, excessive slipping of the clutch, and when the clutch is pressed and an incorrect lower gear is selected, can result in clutch damage. |
| A301722 2019850- | 2018-02-05. Service bulletin. POWER TRAIN:CLUTCH ASSEMBLY. This technical service bulletin provides guidelines for diagnosing the clutch plate. |
