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.

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 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?.

The fault is very sporadic and usually appears after a cold start. Fault is caused by transmission software that is too sensitive.
A371308 2034163-2017-11-17. Service bulletin. POWER TRAIN:AUTOMATIC TRANSMISSION. 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).

Supersedes Technical Service Bulletin Group 35 number 13-11 dated June 11, 2013. One or multiple transmission-related concerns may be present. Harsh downshifting of multiple gears: 7-5, 4-3, 2-1. This may happen during just one of these shifts. A bump is felt after vehicle comes to a stop (2-1 downshift). Fluctuating engine speed after 5-4 shift with accelerator at 80-100% accelerator pedal position (kick-down). The driver information system displays the message "Gearbox complaint! Journey can be continued." After a key cycle the complaint is fixed. The vehicle was parked in gear lever position N and the ignition switched off. DTC P1724 (signal for immobilizer, short circuit to ground) is logged in the transmission control module, J217 (address word 02). Incorrect transmission software.
Dealer Letter -2017-11-08. Service bulletin. POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE (TCM/PCM/TECM); ELECTRICAL SYSTEM:SOFTWARE. This communication is to inform you of upcoming Update 24AS. On Audi vehicles manufactured within a specific period the ECM software needs to be updated to address customer complaints of driveability and rough idle.
A011526 2041120-2017-10-25. Service bulletin. POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE (TCM/PCM/TECM). The MIL is on. DTC P042000 and/or P043000 (Catalyst system Bank 1/2, Efficiency below threshold) is stored in the engine control module (ECM), J623 (address word 01). The diagnostic limitations were too narrow.
