ATF Level, Checking And Correcting
Special tools and workshop equipment required
- Vehicle Diagnostic Tester
- Used Oil Collection and Extraction UnitSMN 372500
- ATF Filler Tool V.A.G 1924
- Protective eyewear
Test Conditions
- The transmission must not be in emergency running
- The vehicle must be horizontal.
- The selector level is in "P".
- Exhaust hose/-hoses of an exhaust extraction system connected.
- Engine running at idle.
- The Air Conditioning (A/C) and heater are off.
- Vehicle Diagnostic Tester is connected.
- At the start of the testing, the ATF temperature must not be higher than 30° C (86° F); let the transmission cool down.
Automatic transmission clean working conditions, refer to CLEAN WORKING CONDITIONS .
Read the ATF temperature on the Vehicle Diagnostic Tester.
The ATF level will vary depending on the temperature of the ATF.
Performing ATF level check when the ATF temperature is too low causes overfilling.
Performing ATF level check when the ATF temperature is too high causes underfilling.
Overfilling or underfilling will influence the function of the transmission.
Only use the ATF available as a replacement part for the planetary gear in automatic transmission 09L. Other oils lead to malfunctions or to failure of the transmission, ATF specification. Refer to SPECIFICATIONS .
Procedure
-- Select the following menu entries on the Vehicle Diagnostic Tester in the Guided Functions :
- 02 - Transmission Electronics 09L
- J217 - Automatic Transmission, Read Measured Values Block
-- Select the Transmission Oil Temperature measured value from the list on the Vehicle Diagnostic Tester.
-- Check the ATF temperature.
ATF Level, Checking and Correcting
The ATF level is checked at the ATF inspection plug.
The ATF level is correct if a small amount of fluid drips out of the inspection hole (this is normal as the fluid expands as it heats up) at an ATF temperature between 35° and 45° C (95° and 113° F) (for hot countries 50° C (122° F)).
-- Drive the vehicle onto a 4-column hoist or over a service pit so that it is absolutely level.
- The ATF filler tool must be clean and the ATF must not be mixed with any other ATF.
- Using different oils will destroy the transmission.
-- Fill the reservoir of the ATF Filler ToolV.A.G 1924 with ATF for automatic transmission 09L; ATF specification. Refer to AUDI A6/S6 .
-- Secure ATF Filler ToolV.A.G 1924 reservoir as high as possible on vehicle.
-- Start the engine and let it idle.
-- Place the Used Oil Collection and Extraction UnitSMN 372500 under the transmission.
Wear protective eyewear.
-- When ATF temperature of 35° C (95° F) is reached, remove the ATF inspection plug -arrow B- and drain off any excess ATF.
-- Replace ATF inspection plug gasket -arrow-.
If ATF drips from ATF inspection hole before ATF has reached 40° C (104° F), ATF level -arrow- is OK.
The ATF inspection plug must be screwed in again before the ATF reaches a temperature of 45° C (113° F) (for hot countries 50° C (122° F)).
Add ATF if no ATF has escaped from the ATF inspection plug hole by 45° C (113° F) ATF LEVEL, CHECKING AND CORRECTING
-- Fasten ATF inspection plug with new gasket to 80 Nm. The ATF level test is now completed.
-- End the function "011 - Measured values" by pressing the ← button.
-- Press "022 - End output".
-- Switch off the ignition and disconnect the diagnostic connector.
ATF LEVEL, CHECKING AND CORRECTING
If no ATF escapes at the ATF inspection opening at 40° C (104° F), ATF must be topped off;
The ATF inspection plug must be screwed in again before the ATF reaches a temperature of 45° C (113° F) (for hot countries 50° C (122° F). Allow transmission to cool and check again.
-- Guide filler hook of ATF Filler ToolV.A.G 1924 into the opening -arrow- of protective cap, do not push cap up and in while doing this.
-- Add ATF using ATF Filler ToolV.A.G 1924 until ATF drips from the check hole.
Too little or too much ATF will impair the transmission.
-- Fasten ATF inspection plug with new gasket to 80 Nm.
-- Switch off the ignition and disconnect the diagnosis connector.
