Affected Vehicles
Condition
Based on customer complaint, follow the procedure below:
Technical Background
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 2.0 TFSI engine can negatively influence the rate of oil consumption.
This condition can occur while the vehicle is operated in metro driving conditions, for example: Stop and go traffic with extended idle periods.
Production Solution
Crankcase pressure reduction starting with model year 2012.
Service
1. Upon customer complaint of excessive engine oil consumption proceed as follows:
^ Replace crankcase pressure regulating valve with part number 06H 103 495 J.
^ Replace front crankshaft seal with part number 06L 103 085 B. (Also requires front crankshaft bolt WHT 001 760).
^ Update the Engine Control Module software using SVM action code as listed in the table above.
^ Follow all instructions TSB 2011732 00 Software Version Management (SVM), operating instructions.
2. Start oil consumption measurement, Part 1.
Tip: Ensure the VAS device is at software level (Base 19 and Brand 19.34) or higher
219
Tip: The electronic oil consumption measurement will only function on the 2.0 TFSI engine with engine code CAEB.
^ Park vehicle on a level surface, the GFF test plan will not continue if vehicle is tilt more than 0.5 degrees (side to side or front to rear).
^ From GFF, select Function/Component Selection >>> Powertrain >>> CAEB - Engine >>> 01-Oil consumption measurement (electronic
measurement).
^ Follow the GFF test plan, Start oil consumption measurement exactly and observe all notes and cautions.
