| A441346 2010334- | 2017-10-31. Service bulletin. WHEELS:LUGS/NUTS/BOLTS/STUDS; WHEELS. Supersedes Technical Service Bulletin Group 44 number 12-32 dated August 2, 2012. Wheel bolt requires torque adjustment. Torque sticks, torque extension bars, and impact guns/wrenches are not approved by Audi of America, Inc., and should not be used to apply torque to wheel bolts. Always use a calibrated torque wrench to attain the correct wheel bolt torque and follow the proper wheel tightening procedure as outlined in Elsa. Proper use of a calibrated torque wrench ensures that all wheel bolts are tightened equally and reduces the chances of repeat repairs. Using methods other than a calibrated torque wrench to attain correct wheel bolt torque may lead to problems. |

The driver?s voice sounds muffled or background noise sounds very loud to other caller during Bluetooth calls. Voice recognition commands are not recognized or voice recognition accuracy is poor. The location of the microphones within the roof module make them susceptible to interference by the vehicle air vents and climate control settings. When the center air vents are pointed upward, they can cause a ?swirling? effect that affects the audio quality of Bluetooth® and voice recognition. This is particularly evident on hot days when the A/C system is set to ?auto?. |

The yellow steering symbol is illuminated in the instrument cluster. DTC C10ACF0 (steering end stops not programmed) is logged in the power steering control module, J500 (address word 44). The power steering control module expects to receive a VIN message over the data bus shortly after terminal 15 is turned on. If the VIN message is not received at the expected time, the power steering control module assumes it has been installed in a new vehicle, and it discards the programmed end position values. |
| A441342 2022563- | 2017-10-31. Service bulletin. SUSPENSION; STEERING. Supersedes Technical Service Bulletin Group 44 number 13-36 dated February 18, 2013. This bulletin is not applicable if this vehicle has a Repair Authorization on this topic. Customer feels vibration in the seat, vehicle floor, footwell, pedals, or steering wheel. This condition does not lead to any handling concerns or loss of vehicle control. The customer feels the vibration in one or both of the following circumstances: * When driving at highway speeds from 55 - 80 mph (88 - 128 km/h). * When applying low brake pedal pressure with minor slow down. The vibrations felt by the customer could be a result of the harmonic vibrations caused by the radial force variation (RFV) of the tires. |
| A441340 2027779- | 2017-10-31. Service bulletin. STEERING. Supersedes Technical Service Bulletin Group 48 number 12-33 dated October 22, 2012. After replacing the electromechanical steering with the control unit J500, the unit cannot be coded via SVM spec/actual. All new replacement power steering control units (J500) must be coded and parameterized using online SVM spec/actual or an SVM code. If the SVM spec/actual returns a response of ?Check Hardware?, then the SVM code is required to code and parameterize the new replacement control unit. The SVM code can be found in Parts Bulletin 9-97, which is available online through ETKA. |
| A421319 2029953- | 2017-10-31. Service bulletin. STRUCTURE:BODY:ROOF AND PILLARS. Supersedes Technical Service Bulletin Group 42 number 12-15 dated October 12, 2012.

| A401335 2023187- | 2017-10-31. Service bulletin. STEERING; WHEELS. Supersedes Technical Service Bulletin Group 40 number 12-23 dated May 14, 2012. Squeaking noises are heard when the steering wheel is turned or maneuvered. The noises may be more prevalent in wet weather. The folds of the outer rubber boots on the front axle shafts may come in contact with each other when the steering wheel is turned, causing squeaking noises. These noises are more likely to occur when the vehicle is new. The volume and occurrence of the noise will dissipate after a short break-in period. |
| A371317 2029027- | 2017-10-31. Service bulletin. POWER TRAIN. Supersedes Technical Service Bulletin Group 37 number 13-02 dated April 26, 2013. Customer may report transmission warning light is illuminated. In some cases, the vehicle will not move after being started and placed into gear. After key cycle, the vehicle drives without restriction. DTCs is stored in the transmission control module (TCM). If DFCCs do not match exactly, this TSB does not apply. |
| A191345 2034439- | 2017-10-31. Service bulletin. ENGINE AND ENGINE COOLING; ENGINE AND ENGINE COOLING:COOLING SYSTEM:RADIATOR ASSEMBLY. Supersedes Technical Service Bulletin Group 19 number 13-43 dated July 12, 2013. The coolant warning light is illuminated. Coolant is leaking from the front intercooler radiator because of stone damage to the radiator. When vehicles are driven on gravel roads, there is a greater chance of front-end stone impact damage to the intercooler radiator. |
| A171341 2027501- | 2017-10-31. Service bulletin. ENGINE. Supersedes Technical Service Bulletin Group 17 number 11-24 dated November 11, 2011. Electronic oil consumption measurement - Repair Authorization Model Year 2012. In order to provide effective lubrication and cooling of internal engine components, all internal combustion engines consume a certain amount of engine oil. Oil consumption varies from engine to engine, and may change significantly over the life of the engine. Typically, engines with specified break-in periods consume more oil during the break-in period, and the oil consumption will stabilize after the break-in period. Refer to the Owner?s Manual for specific break-in procedures. Under normal conditions, the rate of oil consumption depends on the quality and viscosity of the oil, the RPM at which the engine is operated, and the ambient temperature and road conditions. Additional factors are the amount of oil dilution from water condensation or fuel residue and the oxidation level of the oil. Utilizing the advanced sensor technology integrated in the 2009> B8 platform (A4, allroad, A5, A5 Cabriolet, A6, and Q5) equipped with the 2.0 TFSI (CAEB, CPMA) engine, it is possible to measure oil consumption electronically via a Guided Function test plan. The electronic oil consumption measurement will only function on the 2.0 TFSI engine with engine code CAEB and CPMA. |
| A101310 2018288- | 2017-10-31. Service bulletin. ENGINE AND ENGINE COOLING. Supersedes Technical Service Bulletin Group 10 number 10-02 dated September 14, 2010. Prior to engine replacement, any debris lodged in transferred assemblies must be removed. If the vehicle's engine experienced a serious mechanical problem, it is possible that small pieces of metal debris resulting from the mechanical problem may have become deposited in the intake manifold, air intake hoses, exhaust manifolds, exhaust down-pipes, turbocharger, supercharger, and/or intercooler. If these pieces are not removed prior to the installation and operation of the replacement engine, the pieces may be drawn into the combustion chamber, which can cause a knocking noise and subsequent serious engine damage. |
