| Update Bulletin- | 2017-10-31. Service bulletin. EQUIPMENT:ELECTRICAL. Rough idle or reduced driving power and, in turn, an illuminated Malfunction Indicator Lamp (MIL) on the instrument cluster due to the presence of specific fault codes caused by this component. This Update is in effect until removed. Procedure is valid only for vehicles that show the 28G6 code in the ElsaWeb Campaign/Action Information screen on the day of repair. Vehicle must be within the New Vehicle Limited Warranty. Procedure must be performed within the allotted time frame stated in this Technical Service Bulletin. Procedure must be performed on applicable vehicles in dealer inventory prior to sale. A faulty ignition coil can result in rough idling or reduced driving power 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. |
| A481356 2036032- | 2017-10-31. Service bulletin. STEERING. The customer states that the steering feels stiff during turning. The condition occurs when the vehicle is stationary. The steering shaft needs to be updated. |
| 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.

| 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. |
