ATF, Checking Level and Correcting

ATF, Checking Level 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 goggles

Test Conditions

• The transmission must not be in the emergency running

• Move 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 set the electromechanical parking brake.

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

• The Air conditioning (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 necessary.

• ATF temperature appears in the display of the (VAS 5051B).

• 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.

Procedure

- Select the following menu entries on the (VAS 5051B) in "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 "

- Select the measured value "transmission fluid temperature" on the (VAS 5051B).

- Check the ATF temperature.

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 (95 °F and 113 °F) (for hot countries 50 °C (122 °F)).


There is a risk of damaging the transmission.

• Only use the ATF available as a replacement part for the automatic transmission 0B6.

• Using other fluids can cause malfunctions or transmission failure.

• For the correct allocation, refer to the Electronic Parts Catalog (ETKA).

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

- Fill the reservoir on the ATF filler system (V.A.G 1924) with the ATF for the automatic transmission 0B6; for the correct ATF specification, refer to the Electronic Parts Catalog (ETKA).






- Secure reservoir of the (V.A.G 1924) as high as possible on the 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 or Filling after Repair ] ATF, Draining or Filling After Repair.

- 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") 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.


Danger of eye injury.

• Wear protective goggles.

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






• The ATF inspection plug is accessible through the opening on the tunnel crossmember.

• If ATF drips from the ATF inspection opening before the ATF has reached 40 °C (104 °F), the ATF level - arrow - is OK.






• The ATF inspection plug must be installed again before the ATF reaches a temperature of 45 °C (113 °F) (50 °C (122 °F) with hot climates).

- Fasten the ATF inspection plug with new gasket - arrow - to 9 Nm. 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):

Filling the ATF

• The ATF inspection plug must be installed again before the ATF reaches 45 °C (113 °F) (50°C (122 °F) for countries with hot climates). Let the transmission cool down and check again.

- Guide the filler hook of (V.A.G 1924) from underneath into an opening in the cap - arrow -.






- Add ATF using (V.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 - arrow - to 9 Nm. The ATF level test is now completed.






- Remove the ATF residue on the tunnel cross member and clean the cross member thoroughly.






• There are several recesses on the top side of the tunnel cross member where leaking ATF can collect.

• They must be cleaned thoroughly.

• Ignore - arrows -.

- Install the rear noise insulation.
