ATF Level, Checking

ATF Level, Checking

Special tools, testers and auxiliary items required

• Tester (VAS5051)

• Diagnostic cable (VAS5051/1) or ( VAS5051/3)

• Drip tray (VAG1306)

• ATF filler tool (VAG1924)

• Protective glasses

Test requirements:

• Transmission must not be in emergency running mode.

• Vehicle on level ground.

• Selector lever in "P", let engine run at idle.

• A/C system and heating switched off.

• ATF level changes with ATF temperature.

• Performing ATF level check when ATF temperature is too low causes overfilling.

• Performing ATF level check when ATF temperature is too high causes insufficient filling.

• Excess filling and insufficient filling both affect the function of the transmission.

• ATF temperature is read off using the tester (VAS5051 ).

Procedure

- Secure container of ATF filler tool (VAG1924) as high up on vehicle as possible.





- Remove noise insulation panel (arrows).





Connect Tester VAS5051

All functions previously performed with the (VAG1551) can also be performed using the new tester (VAS5051 ) in operating mode "Vehicle On Board Diagnostic (OBD)":

Checking ATF temperature

- Connect tester (VAS5051) to Data Link Connector (DLC) using diagnostic cable (VAS5051/1) with ignition switched off.





- Switch on tester (arrow).





The tester now requires up to 3 minutes to finish booting.

- Switch on ignition.

- Select operating mode: Press "Vehicle Self-Diagnosis" selection on display.

- Press "02 - Transmission electronics" on display.

- Perform dialog to confirm control module number belonging to selected system.

- Select "08 - Read Measuring Value Block" on display.

- Choose Display Group 4 via the "Read Measuring Value Block " and "Change Display Group" touch screen displays.

Display on (VAS5051):





The first line of display field - 1 - displays ATF temperature.

Checking and correcting ATF level

• ATF level is checked at the ATF check plug.

• ATF level is correct if a little bit of fluid still escapes at the ATF check plug between 35 ° and 45 °C *(dependent on the fluid level when warming up)..

* For warm countries 50 °C

- Start engine.

- Raise vehicle.

- Place drip tray (VAG1306) under transmission.

CAUTION!
Wear protective glasses.

- Once an ATF temperature of 35 °C is reached, remove ATF check plug - arrow - and drain excess ATF if necessary.





- If ATF flows out from the ATF filler plug hole before the ATF reaches 40 °C, the ATF level - arrow - is OK.





• ATF check plug must be closed again by 45 °C *at the latest.

* For warm countries 50 °C

• Add ATF if no ATF has escaped from the ATF check plug hole by 40 °C.

• ATF specification, refer to => [ Capacities ] 01VA Transmission.

- Insert ATF filler tool (VAG1924) into an opening (arrow) in the protective cap, but do not knock cap upward.





- Fill with ATF using ATF filler tool (VAG1924) until ATF exits from the check hole.





- Always replace seal (arrow) for ATF check plug.





- Tighten ATF check plug to 80 Nm.

- Switch off motor.

- Select diagnostic function "06 - end output" in selection.

Display on (VAS5051):





- Switch off ignition and disconnect diagnostic connector after this indication is displayed.

- Install noise insulation.
