| A171337 2030197- | 2017-11-17. Service bulletin. ENGINE AND ENGINE COOLING. Supersedes Technical Service Bulletin Group 17 number 13-36 dated February 14, 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. |

| A011255 2030192- | 2017-11-08. Service bulletin. ENGINE AND ENGINE COOLING; ELECTRICAL SYSTEM. MIL light on. P2015 sender of intake manifold flap position/air flow control, implausible signal P2020 sender of intake manifold flap position, intake manifold flap 2, implausible signal. Engine may have reduced performance without significant loss of power or stalling. Check service history to see if the improved ? B? suffix V157 Intake Flap motor has already been installed previously; if yes, only replace the potentiometer seals as described below. The fault entry is made because a linkage of the intake manifold flap adjustment sticks. This is caused by deformed oil seal behind the potentiometers. |
| A011257 2028344- | 2017-11-08. Service bulletin. ENGINE AND ENGINE COOLING:EXHAUST SYSTEM:EMISSION CONTROL:CATALYTIC CONVERTOR; ENGINE AND ENGINE COOLING. Supersedes Technical Service Bulletin Group 01 number 12-51 dated July 18, 2012. Noises/inconsistent engine operation after cold start during the catalyst heating phase. The customer may interpret this engine roughness as misfiring. To comply with the legal requirements on exhaust gas emissions according to the LEV-1 and LEV-2 standards, a high exhaust gas quality must be ensured. The necessary catalyst only operates at a temperature over 300°C (572°F). To achieve this, the catalyst is heated up. The catalyst heating phase is achieved by a late ignition angles and by introducing additional fresh air to the exhaust valves (secondary air system). Late ignition angles make sure that the exhaust gas from the cylinders has a higher temperature. This exhaust gas includes fuel that is un-burnt, and was deliberately injected into great quantities. The secondary air system adds fresh air to the exhaust gas as it leaves the cylinder and the extra fuel is burnt. As a result, the temperature of the exhaust gas and of the catalyst increases quickly. The afterburning in the exhaust manifold before catalyst changes the sound characteristic of the engine. This heating-up of the catalyst, including afterburning, is normal and has no effect on the service life of the engine. During this catalyst heating phase the engine has increased idle speed, may have increased vibrations, and a different sound characteristic. Depending on conditions the time of the catalyst heating phase varies. |

| A011263 2031458- | 2017-11-08. Service bulletin. ENGINE; ELECTRICAL SYSTEM. Supersedes Technical Service Bulletin Group 01 number 12-58 dated November 5, 2012. MIL on, with DTCs stored in the 01 (Engine Control Module). Under extreme driving conditions, such as a driving profile of mainly short distance (stop and go) driving high crankcase pressure can lead to the above described DTC codes. By changing the crankcase pressure valve to a lower operating pressure this condition can be improved and eliminate the mentioned possible DTC codes. Along with the crankcase pressure being lowered, a new ECM software level is required to compensate for new crankcase pressure. |

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. |
| A191450 2025303- | 2017-11-08. Service bulletin. ENGINE AND ENGINE COOLING. Supersedes Technical Service Bulletin Group 19 number 13-41 dated June 20, 2013.

| A011455 2036169- | 2017-11-08. Service bulletin. ENGINE; FUEL SYSTEM, GASOLINE:DELIVERY:FUEL PUMP. The MIL is on. DTC P0087 may be stored in the ECM. Drivability concerns such as hard starting/no starting are present. Outside temperature is sub-freezing. In tank, fuel pump may be making a straining noise. Diesel fuel requires additive blending or ?winterization? to be useable at low temperatures. At temperatures below 20° F (-7° C), No. 2 Diesel with insufficient winterization blending may lose its fluidity due to wax separation. This may clog the fuel filter or in-tank filter, preventing the engine from operating properly. No. 2 Diesel is blended by refineries to various levels of winterization (minimum useable temperature) based on month, geographical location, and the 10th percentile minimum ambient air temperature for the given region. Although rare, during sudden periods of extreme low temperatures (record lows), fuel stations may not be adequately prepared with No. 2 Diesel fuel with sufficient winterization to resist wax formation or ?gelling?. |
