| A171344 2035463- | 2017-10-31. Service bulletin. ENGINE AND ENGINE COOLING. 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 include 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 models equipped with the 3.0 TFSI engine, it is possible to measure oil consumption electronically via a Guided Function test plan. If the electronic oil consumption test is not available for this model, perform the test with the conventional scale/oil weighing method. See TSB 2018550 for instructions for the conventional scale/oil weighing method. |

| A011336 2035235- | 2017-10-31. Service bulletin. FUEL SYSTEM, OTHER:DELIVERY:FUEL PUMP; ENGINE. The customer reports that the engine warning light illuminates sporadically. The engine may have reduced performance without significant loss of power or stalling. Noise is heard coming from the engine compartment, specifically from the High Pressure Fuel Pumps 2. DTCs are stored in the engine control module (ECM). The fuel metering valve of the high-pressure fuel pump is controlled by a specific on/off ratio. If there is a low system voltage, the on/off ratio may not be enough to keep the fuel metering valve constant in all areas. In such a situation, the fuel metering valve is deactivated and the high-pressure fuel pump switches to full supply mode. Because the increased rail pressure does not match the respective driving situation, the DTC appears. |
| A001355 2035581- | 2017-10-31. Service bulletin. ENGINE. 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 a W12 engine, the increased oil flow rate forces oil into the intake manifold or combustion chamber and damages the engine. |
