ATF, Checking Level And Correcting

Special tools and workshop equipment required 

• Vehicle Diagnosis, Testing and Information System VAS 5051B
• Used Oil Collecting and Extracting Device V.A.G 1782
• ATF Filler Tool V.A.G 1924
• Protective eyewear

Test Conditions 

• The transmission must not be in the emergency operating mode.
• Move the vehicle onto a 4-column workshop hoist or over a work pit so it is completely level.
• The selector level is in P.
• The parking brake button should be activated to close the electromechanical parking brake.
• Exhaust hose/-hoses of an exhaust extraction system connected.
• The A/C and the heater are off.
• The VAS 5051B is connected.
• The ATF temperature must not be higher than 30 °C (86 °F) at the beginning of the test. The transmission must cool down first if the temperature is higher.

Procedure 

-- Select the following menu items on the VAS 5051B in the Function/component Selection  in guided fault finding:

• Drive 
• 0B6-Transmission 
• 01-On Board Diagnostic (OBD) Capable Systems 
• 02-Transmission Electronics 
• 02-Transmission Electronics, Functions 
• 02-Read Measured Value Block 

-- Select the measured value from the list Transmission Fluid Temperature  on the VAS 5051B.

-- Check the ATF temperature.

ATF, Checking Level and Correcting

-- Fill the reservoir on the V.A.G 1924 with the ATF for the automatic transmission 0B6; for the correct ATF specification.

-- Start the engine with the selector lever in P.

-- While pressing the brake pedal and with the vehicle idling, shift through all the selector lever positions (P, R, N, D, S) leaving each position engaged for at least 10 seconds.

-- Move the selector lever into N.

-- Increase the RPM to 2000 and hold it there for at least 60 seconds.

-- Move the selector lever into P.

-- Run the engine at idle.

-- Place the V.A.G 1782 under the transmission.

-- When ATF temperature of 35 °C (95 °F) is reached, remove the ATF inspection plug -arrow B- and drain off any excess ATF.
