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.
Utilizing the advanced sensor technology integrated in the 2009> B8 platform (A4, A5, A5 Cabriolet, A6 and Audi Q5) equipped with the 2.0 TFSI (CAEB) engine, it is now possible to measure oil consumption electronically via a GFF test plan.
The advantages of an electronic measurement are:
^ No engine oil required (only for top up)
^ No hoist required
^ Increased accuracy
^ No manual paperwork (all information stored in GFF diagnostic log)
Tip: The electronic oil consumption measurement will only function on the 2.0 TFSI engine with engine code CAEB.
Production Solution

The customer should not add any oil.
Evaluate measurement (following road test), Part 2
1. When the customer returns the vehicle to the dealership, perform Part 2 Evaluate measurement of the Oil Consumption Test.
2. Contact Audi Technical Assistance Center (TAC) with all test results.
3. You must attach both the GFF log and the oil measurement test sheet to the TAC ticket prior to contacting a TAC consultant.
