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 Filler Tool (V.A.G 1924)
• Protective eyewear
Test Conditions
• The transmission must not be in the emergency operating mode.
• Move the vehicle onto a 4-column workshop hoist or over a work pit so it is completely level.
• The selector level is in P.
• The parking brake button should be activated to close the electromechanical parking brake.
• Exhaust hose/-hoses of an exhaust extraction system connected.
• The A/C and the heater are off.
• The Vehicle Diagnostic Tester 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 the temperature is higher.
• ATF temperature appears in the display of Vehicle Diagnostic Tester.
• The ATF level will vary according to 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 overfill the ATF if the level is checked when the temperature is too high.
• Overfilling or under filling will influence the function of the transmission.
Procedure
- Select the following menu items on the Vehicle Diagnostic Tester in the 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 Block
- Select the measured value from the list Transmission Fluid Temperature on the Vehicle Diagnostic Tester.
- 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 (95 °F) and 45 °C (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.
• Other oils can cause malfunctions or transmission failure.
• For the correct allocation, refer to the Parts Catalog.
• The ATF filler tool must be clean and the ATF must not be mixed with any other ATF.
- Fill the reservoir on the (V.A.G 1924) with the ATF for the automatic transmission 0B6; for the correct ATF specification, refer to the Parts Catalog.
- Secure 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 => [ ATF, Draining or Filling after Repair ] ATF, Draining or Filling After Repair.
- Remove the rear noise insulation.
- 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 eyewear.
- When 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 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 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 crossmember and clean the crossmember thoroughly.
• There are several recesses on the top side of the tunnel crossmember where leaking ATF can collect.
• They must be cleaned thoroughly.
• Ignore - arrows -.
- Install the rear noise insulation.
