2008 Volkswagen Jetta

Technical Bulletin (Oil Consumption Measurement): Customer states oil consumption is higher than the Volkswagen oil consumption standard of up to 0.5 quarts per 600 miles, or 0.5 liters per 1000 km. 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 Owners 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. Further factors include the amount of oil dilution from water condensation or fuel residue and the oxidation level of the oil. This document discusses the "Fault Codes" necessary to diagnosis, and potential remedy of the issue. The fault codes for checking warranty coverage for servicing the vehicle are also available.

Tech Tips 92006-2014 Vehicles with 2.0T Gasoline Engine - N75 Solenoid Valve Diagnosis): When diagnosis on the above engine leads to the testing of the N75, please refer this document with graphical aid. The diagram shows which vacuum ports on the N75 valve should hold vacuum and which ones should not. Turbocharger fault codes P0299 and P0234 can be diagnosed using this test.

Tech Tips (Instrument Cluster Production Mode): During PDI, or after installation of a replacement cluster, ?Pro? may be displayed in place of the odometer. The high beam indicator may be flashing in the instrument cluster as well. This indicates the cluster is in Production mode. Production mode is not the same as ?Transport? mode. This document infroms of the difference between Production, and Transport mode.
