ATF Level In Planetary Gearing, Checking and Correcting

ATF Level In Planetary Gearing, Checking and Correcting

Special tools, testers and auxiliary items required

• Vehicle Diagnosis, Testing and Information System ( VAS 5051B)

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

• ATF Filler Tool (V.A.G 1924)

• Protective glasses

Test Conditions

• Transmission not in emergency operating mode.

• Move the vehicle onto a 4-column lifting platform or over a work pit so it is completely level.

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

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

• Air conditioning and heater switched off.

• Vehicle Diagnosis, Testing and Information System ( VAS 5051B) connected, "OBD", Vehicle System " 02 - Transmission Electronics", "Measured Values, Display Group 4" selected.

• ATF temperature must not be higher than 30 °C at start of test, allow transmission to cool down if necessary.

Checking ATF temperature

Display on (VAS 5051B):





- Read off ATF temperature indicated in display field - 1 -.

ATF, Checking Level 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 opening (this is normal as the fluid expands as it heats up) at an ATF temperature between 35 °C and 45 °C (for hot countries 50 °C).

- Fill the reservoir of the ATF Filler Tool (V.A.G 1924) with ATF for automatic transmission 01V; ATF specification => [ Capacities ] 01V,01VA Transmission.

CAUTION!
The ATF filler tool must be clean and the ATF must not be mixed with any other ATF oils!

- Secure ATF Filler Tool (V.A.G 1924) reservoir as high as possible on vehicle.





- Start engine and allow it to run at idle.

- Remove the noise insulation - arrows -.





- Place Used Oil Collection and Extraction Device ( V.A.G 1782) under transmission.





CAUTION!
Wear protective glasses.

- When ATF temperature of 35 °C is reached, remove ATF inspection plug - 2 - and drain off any excess ATF.

- Replace ATF inspection plug gasket - arrow -.





If ATF drips from ATF inspection opening before ATF has reached 40 °C, ATF level - arrow - is OK.





• The ATF inspection plug must be screwed in again before the ATF reaches a temperature of 45 °C (for hot countries 50 °C).

Add ATF if no ATF has escaped from the ATF inspection plug hole by 45 °C.

- Tighten ATF inspection plug with a new gasket to 80 Nm. The ATF check is now completed.

- End the "OBD", switch off the ignition and unplug diagnostic connector.

Filling ATF

If no ATF escapes at the ATF inspection opening at 40 °C, ATF must be topped off;

• The ATF inspection plug must be screwed in again before the ATF reaches a temperature of 45 °C (for hot countries 50 °C). Allow transmission to cool and check again.

- Guide filler hook of ATF Filler Tool (V.A.G 1924 ) into an opening - arrow - of protective cap, do not push cap up and in while doing so.





- Add ATF using ATF Filler Tool (V.A.G 1924) until ATF drips from the inspection opening.

• If the ATF level is too high or too low it will adversely affect the operation of the transmission.

- Fasten ATF inspection plug with new gasket to 80 Nm.

- End the "OBD", switch off the ignition and unplug diagnostic connector.
