Service bulletins for the 2013 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.

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.
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?.

Dealer Letter -2017-11-08. Service bulletin. POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE (TCM/PCM/TECM); ELECTRICAL SYSTEM; EQUIPMENT; STEERING; EXTERIOR LIGHTING:HEADLIGHTS. This document contains information on delivering the perfect audi vehicle and to pay special attention to completing any update technical bulletins that are active on the 2013 model year vehicles.
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.
A351620 2030477-2017-10-04. Service bulletin. POWER TRAIN:AUTOMATIC TRANSMISSION. Gearbox malfunction message in cluster. DTCs P17D800, P179D00, P174000, P174C, P174B, P174F, P179C, P174A, and/or P174E are stored in the transmission control module. Fault codes and symptom codes must match exactly or this TSB should not be followed. Poor internal contact area on circuit board will lead to faults. Oil additives can cause the plastic circuit plates to delaminate, causing contact loss.
A351619 2032211-2017-10-04. Service bulletin. STEERING:GEAR BOX (OTHER THAN RACK AND PINION); POWER TRAIN:AUTOMATIC TRANSMISSION; ELECTRICAL SYSTEM. Gearbox warning light on (DTCs P179E00, P179F00, P0700, P060A). The driver information system displays the message "gearbox malfunction: you can continue driving". There are two scenarios present. Scenario 1 is that entries are logged individually or in combination, with P179E logged first (using DTC environmental data).The entries are DTC P179E (Drive position sensor electrical error), DTC P0700 with DFCC 20196 (Transmission control system malfunction), DTC P1758 with DFCC 8464 (Terminal 15 voltage supply open circuit), and DTC P060A with DFCC 8126, 8345 (Internal control module monitoring processor performance) In this scenario, if DTC P179E is not logged first, this TSB does not apply. Scenario 2 is that entries are logged individually or in combination. The order in which the DTCs are logged is not relevant. The entries are DTC P179E with DFCC 8050, 8051, 8052, 8053, 17595, 17596, 17597, 17598, 17602 (Drive position sensor electrical error), DTC P179F with DFCC 8054, 8055, 8056, 8057, 17599, 17600, 17601 (Drive position sensor malfunction), DTC P0716 with DFCC 8096, 8101, 18153, 20738 (Input turbine/speed sensor ?A? circ. range/performance), DTC P171F with DFCC 8097, 8102, 18154 (Transmission input speed (RPM) sensor 2 implausible signal), DTC P0715 with DFCC 8094, 8103, 18161 (Input turbine/speed sensor ?A? circuit.), DTC P2765 with DFCC 8095, 8104 (Input turbine/speed sensor ?B? circuit), DTC P0501 with DFCC 8098 (Vehicle speed sensor ?A? range/performance), and DTC P2159 with DFCC 8099 (Vehicle speed sensor ?B? range/performance). Fault codes and DFCC codes must match exactly for this TSB to apply. The DFCC is the 4-6 digit code that is typically listed before the fault code. Incorrect driving mode sensor module.
