| A191346 2033491- | 2017-10-31. Service bulletin. ENGINE AND ENGINE COOLING:COOLING SYSTEM; ENGINE AND ENGINE COOLING. Supersedes Technical Service Bulletin Group 19 number 13-44 dated July 18, 2013. Customer may report coolant leaking from the engine area.

| A171346 2030197- | 2017-10-31. Service bulletin. ENGINE AND ENGINE COOLING:COOLING SYSTEM; ENGINE AND ENGINE COOLING. Supersedes Technical Service Bulletin Group 17 number 13-45 dated October 23, 2013. Customer complains of excessive oil consumption. 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, 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. Under certain driving conditions, internal engine pressure conditions in the 3.0 TFSI engine can negatively influence the rate of oil consumption. This can occur while the vehicle is operated in city driving conditions, for example: stop and go traffic with extended idle periods. |
| A901343 2035937- | 2017-10-31. Service bulletin. SEAT BELTS; SEAT BELTS:FRONT:WARNING LIGHT/DEVICES. The seatbelt warning light is illuminated, but the passenger seatbelt is buckled.

| A461363 2034181- | 2017-10-31. Service bulletin. SERVICE BRAKES. Customer may report hearing brake noise from front or rear brakes. Customers may describe these noises as a squeal, squeak, grinding, groaning, thumping, or creaking. |
| 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. |

| A011349 2035454- | 2017-10-31. Service bulletin. ELECTRICAL SYSTEM. Supersedes Technical Service Bulletin Group 01 number 13-35 dated October 8, 2013. During reset of the service reminder, the message ?AIR system - action required - observe test plan? appears on the ODIS tester. MIL is not illuminated. Under certain driving conditions, the secondary air ports in the cylinder head can accumulate carbon over time, causing a restriction. The ODIS tester can identify the state of the restriction, and will request that the system is cleaned in order to prevent the MIL from illuminating. |
| A011348 2033001- | 2017-10-31. Service bulletin. ENGINE. Supersedes Technical Service Bulletin Group 01 number 13-37 dated October 10, 2013. MIL on. DTCs are stored in the engine control module.

| A011345 2031458- | 2017-10-31. Service bulletin. ENGINE. Supersedes Technical Service Bulletin Group 01 number 13-66 dated January 17, 2013. MIL on. DTCs are stored in the engine control module (ECM). Under extreme driving conditions (such short-distance, stop-and-go driving), high crankcase pressure can cause the DTCs to appear. The condition can be improved and the DTCs eliminated when the crankcase pressure valve is changed to a lower operating pressure and the ECM software is updated to compensate for new crankcase pressure. |
| Update Bulletin | 2017-10-31. Service bulletin. STEERING.
