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.

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. |
| A011491 2028842- | 2017-12-05. Service bulletin. EQUIPMENT:OTHER:OWNERS/SERVICE/OTHER MANUAL. Customer vehicle is fitted with unauthorized ECM tuning. All systems on Audi vehicles are engineered to work together using the factory calibrations, which have been extensively tested and validated before the vehicle is released for sale. The Audi warranty coverage is based on the results of developing the vehicle under the factory calibration. If a vehicle is equipped with unauthorized hardware or software tuning, it can cause stress on vehicle components outside of intended design limits, and can cause damage and additional wear. Subsequently, factory powertrain warranty coverage is reduced or voided. |
| A171452 2038119- | 2017-12-05. Service bulletin. ELECTRICAL SYSTEM: INSTRUMENT CLUSTER/PANEL. Supersedes Technical Service Bulletin Group 17 number 14-51 dated August 18, 2014.

The washer solvent level warning is on in the DIS, but the washer solvent level is correct. There is no functional restriction in the windshield washer system. The sensitivity of the washer solvent level sensor (G33) can be affected by the type, concentration, and the presence of additives in the washer solvent currently in the tank. The operation of the level sensor relies on the composition of the solvent to provide an accurate message on the solvent level. Incorrect concentration and the presence of additives can contaminate the sensor and reduce its sensitivity. |

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. |
| A481347 2034351- | 2017-12-05. Service bulletin. STEERING. Supersedes Technical Service Bulletin Group 48 number 13-45 dated July 10, 2013. Customer may report hearing creaking or squeaking noise from the steering column when steering slowly (the noise can be duplicated while the vehicle is stationary if the steering wheel is turned slowly). The noise may get louder at higher temperatures or when the vehicle is driven for a longer period of time. The noise comes from the sealing sleeve/steering column opening on the bulkhead. Listen to the attached audio file for example of the noise. Insufficient lubrication of the intermediate steering shaft in the area of the sealing sleeve. |
| A641329 2020552- | 2017-12-05. Service bulletin. VISIBILITY:WINDSHIELD. Windshield is streaked, has a snakeskin appearance, or its surface feels rough. Residue from industrial fallout as well as normal road dirt and grime may accumulate on windshield. |

Parts of the speakers (such as the brackets, cables, or covers) or parts of the interior fittings (such as door covers, rear shelf, facings, or covers) can vibrate at certain frequencies, causing noises. The radio tuner or other control modules may be affected by electromagnetic interference from aftermarket electronic devices. |
| AWA-13-07 | 2017-12-05. Service bulletin. ENGINE AND ENGINE COOLING:EXHAUST SYSTEM:EMISSION CONTROL. As part of Audi's ongoing commitment to our environment, Audi is extending the Emissions Control Systems Warranty to cover cleaning of the engine cylinder head secondary air ports to remove carbon buildup under specific conditions to 10 years or 120,000 miles, whichever occurs first, from the vehicle's original in-service date for certain 2009-12 Model Year Audi vehicles with 3.2L engine, and certain 2009-2013 Model Year Audi vehicles with 3.0T engines. The vehicle's original in-service date is defined as the date the vehicle was delivered to either the original purchaser or the original lessee; or if the vehicle was first placed in service as a "demonstrator" or "company" car, on the date such vehicle was first placed in service. The warranty extension is fully transferable to subsequent owners. Audi has determined that under certain driving conditions, carbon buildup can occur in the engine cylinder head secondary airports. Due to the presence of specific fault codes caused by this carbon buildup, the Malfunction Indicator Lamp (MIL) on the instrument cluster may illuminate. The MIL is part of the on-board diagnostic system. In some locales, an illuminated MIL could cause the vehicle to fail an IM emissions inspection, vehicle registration application could be denied. Audi will diagnose, and if necessary clean the engine cylinder head secondary air ports to remove the carbon buildup at no cost to the customer as long as the vehicle is within the time and mileage limits of the warranty extension. This warranty extension covers only the diagnosis and cleaning of the cylinder head secondary air ports to remove the carbon buildup. Reimbursement is applicable only to the repairs described in this Warranty Bulletin. |
| AWA-13-09 | 2017-12-05. Service bulletin. FUEL SYSTEM, GASOLINE:FUEL INJECTION SYSTEM. Audi has determined that a faulty fuel injector may cause minor misfire conditions and, in turn, cause the Malfunction Indicator Lamp (MIL) on the instrument cluster to illuminate due to the presence of specific fault codes caused by this component. Please note that it is highly unlikely that the vehicle will experience an issue with multiple fuel injectors at the same time. The MIL is part of the on-board diagnostic system. Please refer to the owner's manual for additional information about the MIL. In some locales, an illuminated Malfunction Indicator Lamp could cause the vehicle to fail an IM emissions inspection, and the vehicle registration application could be denied. Be aware that other conditions (unrelated to the issue described in this bulletin) may cause the MIL in the vehicle to illuminate. Customers should be prepared to cover all diagnosis and repair costs for these other, unrelated conditions. This warranty extension covers only the diagnosis and replacement of a faulty fuel injector. |
