ATF, Checking Level and Correcting

ATF, Checking Level and Correcting

Special tools, testers and auxiliary items required

• Vehicle Diagnostic Tester

• Oil Collecting and Extracting Device (V.A.G 1782)

• ATF Filling Tool (V.A.G 1924)

• Protective Goggles

Test Conditions

• The transmission must not be in the emergency running

• Move the vehicle onto a four-pillar shop hoist or over a work pit so that it is absolutely horizontal.

• The selector level is in "P".

• The parking brake button should be activated to close the electro-mechanical parking brake.

• Exhaust hose/-hoses of an exhaust extraction system connected.

• The Air Conditioning (A/C) and the heater are off.

• vehicle diagnostic tester is connected.

• The ATF temperature must not be higher than 30 °C (86 °F) at the beginning of the test. Let the transmission cool down first, if necessary.

• Read the ATF temperature on the vehicle diagnostic tester.

• The ATF level will vary depending on the temperature of the ATF.

• It is possible to overfill the ATF if the level is checked when the temperature is too low.

• It is possible to underfill the ATF if the level is checked when the temperature is too high.

• Overfilling or underfilling will influence the function of the transmission.

ATF, Checking Level and Correcting

- Select the following menu points from the vehicle diagnostic tester in the Functions/Component selection for the "Guided Fault Finding" :

• Drive

• 0B5 Transmission

• 01 - On Board Diagnostic (OBD) Capable Systems

• 02-Transmission Electronics

• 02-Transmission Electronics, Functions

• 02-Measured Values

- Select Transmission Fluid Temperature from the list.

- Check the ATF temperature.

There is a risk of damaging the transmission.

• Only use replacement part ATF for the S-Tronic transmission 0B5.

• Allocation, refer to the Parts Catalog

• Using other types of ATF ATF can result in the malfunctions or transmission failure.

• The ATF filler tool must be clean and the ATF must not be mixed with any other oils.

- Fill the (V.A.G 1924) with ATF for S-Tronic transmission; ATF specification, refer to the Parts Catalog.






- Secure the reservoir of (V.A.G 1924) as high as possible on vehicle.

There is a risk of damaging the transmission.

• Engine must not be started if only a small amount or no ATF is in the transmission after repair work or after significant ATF loss.

• In this case, pre-filling is necessary, refer to => [ ATF, Draining and Filling ] ATF, Draining and Filling.

- Remove the rear noise insulation - 2 -.






- 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" or "D/S") leaving each position engaged for at least 2 seconds.

- Move the selector lever into "N".

- Move the selector lever into "P".

- Run the engine at idle.

• The ATF level is checked at the ATF inspection plug.

• ATF level is correct if a little bit of fluid still leaks out of the ATF inspection plug between 30 °C and 50 °C (86 °F and 122 °F) (dependent on the fluid level rising as the fluid warms up).

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






Danger of eye injury.

• Wear protective goggles.

- When the ATF reaches 30 °C (86 °F), remove the ATF check plug - arrow - and drain off any excess ATF if necessary.

• If ATF starts to leak out of the ATF inspection opening before it reaches 40 °C (104 °F), then the ATF level is OK.

• ATF inspection opening must be closed again by 50 °C (122 °F) at the latest.

- Tighten the ATF inspection plug. The ATF level test is now completed.

- Install the noise insulation.

• If no ATF drips out of the ATF inspection opening when the temperature has reached 40 °C (104 °F):

ATF, Filling

• ATF inspection plug must be closed again at the latest at 50 °C (122 °F), if necessary, turn off the engine, let the transmission cool off and repeat test.

- Engage the filler hook from the (V.A.G 1924) into the ATF inspection opening.

- Add ATF using (V.A.G 1924) until ATF drips from the check hole.

• Too little or too much ATF will impair the transmission.

- Tighten the ATF check plug - arrow -. The ATF level test is now completed.






- Install the noise insulation.
