Service bulletins for the 2011 Audi S4

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.

AWA 22-032022-05-05. Service bulletin. POWER TRAIN:AUTOMATIC TRANSMISSION; EQUIPMENT:OTHER:OWNERS/SERVICE/OTHER MANUAL. This Document informs dealers on the new DSG transmission warranty extension for 2010-2012 S4 & S5 vehicles
35 13 15 20304772022-05-02. Service bulletin. POWER TRAIN:AUTOMATIC TRANSMISSION:GEAR POSITION INDICATION (PRNDL). The following message appears in the information display: ?Gearbox malfunction: you can continue driving.
37 14 30 20036582022-05-02. 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 13 09 20287152022-05-02. 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 08 20341632022-05-02. Service bulletin. POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE (TCM/PCM/TECM); ELECTRICAL SYSTEM:SOFTWARE. Software error in the transmission control module. Customer may report that the transmission does not work correctly. ? Shortly after a cold start, the following message appears in the instrument cluster display: ?Gearbox Malfunction! Journey can be continued?. The gearbox is in limp mode until the key is cycled. ? The issue is very sporadic and cannot be reproduced with a test drive. ? DTC P17E1 (Gear positioner 2 mechanical malfunction) with DFCC 9473 is stored in the transmission control module, J743 (address word 02). ? The DFCC is the 4-6 digit code that is typically listed before the fault code (Figure 1).
35 14 17 20322112022-05-02. Service bulletin. EQUIPMENT; ELECTRICAL SYSTEM; POWER TRAIN:AUTOMATIC TRANSMISSION:FLUID/LUBRICANT. Incorrect driving mode sensor module. The driver information system displays the message ?Gearbox malfunction: you can continue driving?.
35 14 16 20273632022-05-02. Service bulletin. POWER TRAIN:MANUAL TRANSMISSION. One or multiple transmission-related concerns may be present, including:
35 13 11 20273632022-05-02. Service bulletin. POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE (TCM/PCM/TECM); ELECTRICAL SYSTEM:SOFTWARE. Incorrect transmission software.
34 13 13 20286502022-05-02. Service bulletin. POWER TRAIN. Customer states constant howling, droning, or scraping noises heard from the front of the vehicle when accelerating lightly. The ball bearing for the left flange shaft spins in the gearbox housing because of a gap between the outer bearing ring and the support bracket. This can result in grinding marks and swarf (Figure 1, Figure 2).
30 13 18 20282292022-05-02. Service bulletin. POWER TRAIN:MANUAL TRANSMISSION; ELECTRICAL SYSTEM. There may be clutch mechanism wear. Customer may report that the vehicle does not start or only starts when the clutch pedal is pressed very firmly. The message ?Press clutch pedal to start vehicle? may appear in the instrument cluster.
3513152030477 62021-12-13. Service bulletin. POWER TRAIN. The following message appears in the information display: ?Gearbox malfunction: you can continue driving?.
A351833 2028085-2018-10-15. Service bulletin. EQUIPMENT; POWER TRAIN. This bulletin contains instructions for diagnosing transmission leaks and repairing them.
A371882 2051685-2018-09-17. Service bulletin. EQUIPMENT; POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE (TCM/PCM/TECM). This bulletin contains repair instructions for when DTC P179E00 is stored and the mechantronic unit and/or gear sensor G676 are being replaced.

Fault codes and symptom codes must match exactly or this TSB should not be followed. Instructions for obtaining the symptom codes are in the Service section of this bulletin. Poor internal contact area on circuit board will lead to faults. Oil additives can cause the plastic circuit plates to delaminate, causing contact loss.
A371309 2028715-2017-12-05. Service bulletin. POWER TRAIN. Supersedes Technical Service Bulletin Group 37 number 12-40 dated February 28, 2012.

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.
