Service bulletins for the 2010 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.

| A921409 2038151- | 2017-12-05. Service bulletin. VISIBILITY:WINDSHIELD. Supersedes Technical Service Bulletin Group 92 number 14-08 dated August 19, 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. |

| 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. |
| Customer Letter | 2017-12-05. Service bulletin. ENGINE AND ENGINE COOLING. Audi has determined that, under certain driving conditions, carbon buildup can occur in the engine cylinder head secondary air ports. 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 your on-board diagnostic system. Please refer to your owner's manual for additional information about the MIL. In some locales, an illuminated Malfunction Indicator Lamp could cause your vehicle to fail an IM emissions inspection, and your vehicle registration application could be denied. Please be aware that other conditions (unrelated to the issue described in this letter) may cause the MIL in your vehicle to illuminate. Customers should be prepared to cover all diagnosis and repair costs for these other, unrelated conditions. |
| A911392 2030947- | 2017-12-05. Service bulletin. EQUIPMENT:ELECTRICAL; ELECTRICAL SYSTEM:SOFTWARE. Supersedes Technical Service Bulletin Group 91 number 12-61 dated September 25, 2012. The customer complains that when he or she is trying to place a phone call from the vehicle while using a Bluetooth®-connected phone, the phone call disconnects before it begins and an error shows on the MMI display. The message may be "Function not supported" or "Network error". The customer is using a phone with the Android operating system. In addition, Skype®, or another network-based communication software, is installed on the phone. Call can be placed directly from the phone without a problem. When the phone gets the request to place a call from the vehicle, a prompt appears on the phone asking the user to choose how the call should be placed. If the prompt is ignored, the MMI system disconnects the call assuming the phone is not responding. |
| A911388 2021780- | 2017-12-05. Service bulletin. ELECTRICAL SYSTEM; EQUIPMENT:ELECTRICAL:RADIO/TAPE DECK/CD ETC.. Supersedes Technical Service Bulletin Group 91 number 10-70 dated October 26, 2010. Sequence of error messages are seen on the radio display screen after a CD was loaded into or removed from the internal CD drive. "Drive defective. The error could be corrected by resetting it (see radio system owner's manual). Otherwise, contact your Audi dealer." "The CD-drive is damaged and was therefore deactivated." The CD drive cannot be selected in the Source list and is described as "damaged." After the ignition is cycled or a radio reset performed, the CD drive is fully operational. DTC 00468 (CD-ROM Drive -R92- Faulty) is stored in the radio (address word 56). The DTC will be sporadic if the ignition has been cycled or a radio reset performed and will automatically be cleared after 40 ignition cycles without a reoccurrence. Only vehicles with the CAN-based generation 3 radio (Concert (PR 8UQ) or Symphony (PR 8YN)) are affected. |

If the customer does not identify the sound as the sound of the parking brake being actuated, he or she may simply complain of hearing noises from the rear brakes. Ignition is switched off. Steering is locked. Park is selected. Parking brake is not engaged. If the electro-mechanical parking brake is not operated for some time, the free play between brake pads and brake discs increases because of normal brake pad wear. The parking brake control unit performs an automatic correction about every 621 miles (1,000 km). On A8 models, the brake pad thickness is also calculated. |
| A441338 2034445- | 2017-12-05. Service bulletin. TIRES:PRESSURE MONITORING AND REGULATING SYSTEMS. Customer reports seeing the messages "TPMS" and "Tire pressure: System malfunction!" in the instrument cluster. The "TPMS" message is not related to a loss of tire pressure. The message only indicates that tire pressure monitoring system (TPMS) is not active. |
