| A171232 2018550- | 2017-11-08. Service bulletin. ENGINE. Supersedes Technical Service Bulletin Group 17 number 12 - 31 dated August 30, 2012. Oil consumption measurement - Repair Authorization (CA). 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. |
| A431211 2018765- | 2017-11-08. Service bulletin. ELECTRICAL SYSTEM; ENGINE AND ENGINE COOLING. Supersedes Technical Service Bulletin Group 43 number 12-08 dated February 2, 2012. The self-leveling system cannot be adjusted any more with the MMI. The compressor for the self-leveling system continues to run after switching off the engine and locking the vehicle. DTCs may be stored. Because of poor performance or failure of the compressor for air suspension, the vehicle position cannot be adjusted. As a safeguard, the control module will lower the vehicle to the lowest position and illuminate the warning light. Drivability is not affected. |
| A001463 2033576- | 2017-11-08. Service bulletin. ENGINE; EQUIPMENT:OTHER:OWNERS/SERVICE/OTHER MANUAL. Supersedes Technical Service Bulletin Group 00 number 13-49 dated May 14, 2013. Although the correct amount of oil was added to the engine during an oil change service, a check of the oil level shows that the oil level is not okay. When an unapproved aftermarket speed-filling device is used to add oil to the engine, the increased oil flow rate may force oil into the intake manifold or combustion chamber, creating the potential for engine damage. |
| A201434 2035073- | 2017-11-08. Service bulletin. EQUIPMENT:ELECTRICAL; ENGINE AND ENGINE COOLING. Supersedes Technical Service Bulletin Group 20 number 14-32 dated March 21, 2014. The MIL is on. DTC P045600 (EVAP System Leak Detected NVLD (very small leak)) is stored in the engine control module (ECM), J623 (address word 01). Drivability is not affected. The NVLD pressure switch may erroneously detect a very small leak. |
| A191450 2025303- | 2017-11-08. Service bulletin. ENGINE AND ENGINE COOLING. Supersedes Technical Service Bulletin Group 19 number 13-41 dated June 20, 2013. Discontinuation and mixing of Audi-approved engine coolants. G11, G12, and G12+ coolants have been replaced by an improved version. G12++ coolant (for service available) has been introduced in MY 2005 for all engines. G13 has been introduced in MY 2008 as factory filling and service. |
| A971441 2036764- | 2017-11-08. Service bulletin. ENGINE; ELECTRICAL SYSTEM. The MIL is on. Vehicle will not start. DTC P068A00 is stored in the engine control module (ECM), J623 (address word 01). Numerous unrelated DTCs are also stored in the system. The motronic engine control module power supply relay, J271, is not functioning properly. Because the J271 relay controls battery voltage (Terminal 30) via a ground signal sent from the ECM, numerous faults can occur in multiple control modules when it is not functioning properly. |
| A801406 2033806- | 2017-11-08. Service bulletin. ENGINE AND ENGINE COOLING:COOLING SYSTEM. Supersedes Technical Service Bulletin Group 80 number 13-05 dated September 11, 2013. Malfunction Indicator Lamp is on. Climate system heating performance is insufficient. Coolant level warning is on. Engine temperature is elevated. "Limp Home" mode is active. Faults are stored in the transmission control module (address word 02). Coolant loss is found from one or more control valves: N82, N509, or N488. Coolant may have migrated into the wiring harness through the connector and into various control units. Climate system heating performance is insufficient due to coolant loss, or due to a faulty N82 control valve. Inspection of the coolant control valves N82, N509, or N488 reveals the presence of coolant inside the electrical connector as shown in the illustration. The connectors, wiring harness, and/or connected control units may have been damaged from exposure to coolant. |
| A201432 2035073- | 2017-11-08. Service bulletin. ENGINE AND ENGINE COOLING. upersedes Technical Service Bulletin Group 20 number 14-31 dated January 9, 2014. The MIL is on. DTC P045600 (EVAP System Leak Detected NVLD (very small leak)) is stored in the engine control module (ECM), J623 (address word 01). Drivability is not affected.
