Supersedes Technical Service Bulletin Group 17 number 10-01 date February 5, 2010 for reasons listed below.
Affected Vehicles
Condition
Customer states oil consumption is higher than the Audi oil consumption standard of up to 1 quart per 1,200 miles, or 1 liter per 2000 km.
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 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. Additional factors are the amount of oil dilution from water condensation or fuel residue and the oxidation level of the oil.
Production Solution
Not applicable.
Service
1. Before testing or attempting repair, explain the Technical Background to the customer.
2. If the vehicle is within the New Vehicle Limited Warranty, you must obtain authorization from the Audi Technical Assistance Center before proceeding to part 1 of the test. When creating a TAC ticket, in the field Concern Type, select Oil Consumption Repair Authorization.
Oil Consumption Test, Part 1
1. Perform the test plan in the VAS5051 tester before making any repairs. Select Function/Component Selection: Powertrain >> Engine >> Engine lubrication >> Partial systems >> Oil consumption measurements.
2. Follow VAS5051 test protocol exactly. Document all information on oil measurement sheets.
3. Archive the VAS5051 diagnostic log and oil measurement test sheets in the vehicle service file.
4. Advise the customer that if the low oil level warning light comes on before the 630 mile (1,000 km) test is finished, the vehicle must be taken directly to the dealership for Part 2 of the oil consumption test, regardless of the miles accumulated. The customer should not add any oil.

Oil Consumption Test, Part 2
1. When the customer returns the vehicle to the dealership, begin Part 2 of the oil consumption test.
2. Contact Audi Technical Assistance Center (TAC) with test results before performing any repairs. You must attach both the GFF log and the oil measurement test sheet to the TAC ticket prior to contacting a TAC consultant.
Note:
The GFF oil consumption test can also be used for older engines not listed in the GFF test plan since the test and procedure are identical for all engines. Please use any current engine code.
