Checking and topping up ATF: Notes

→ Let the fluid cool down.

→ Wear personal protective gear.

→ Protect components from dirt and contamination.

→ Clean or replace dirty components.

→ Do not start the engine.

→ Do not tow the vehicle.

Information 

Only use oil approved by Porsche in the Porsche Doppelkupplung (PDK), see Parts Catalogue.

Information 

• Read out the ATF temperature using the PIWIS Tester  .
• The ATF temperature must not be higher than 30°C at the beginning of the ATF test.
• The ATF level changes as the ATF temperature changes.
• Perform ATF test when the engine running and selector lever in position P.
• An ATF test performed when the ATF temperature is too low will result in overfilling.
• An ATF test performed when the temperature is too high will result in insufficient filling.
• An ATF level that is too high or too low will impair the function of the transmission.

Information 

• The ATF level is checked at the ATF inspection plug.
• The ATF level is correct if a small amount of fluid still emerges at the ATF inspection plug at an ATF temperature of between 30° and 50°C.

Information 

Always pay particular attention to the following before raising the vehicle:

• Deactivate the levelling system before raising the vehicle (press and hold the levelling system button for at least 10 seconds)  .
• If a transmission range will be engaged while the vehicle is raised, the levelling system must be deactivated beforehand using the PIWIS Tester  . To do this, select >>Levelling system/PASM<<>>Drive links/checks<<>>Activate/deactivate levelling system (without wheel rotation detection)<< in the control unit overview. Select the value "Deactivate levelling system (permanently)" and press "Start" [F8] to execute the function. Re-activate the levelling system when the work is complete. To do this, select >>Drive links/checks<<>>Conclude initial commissioning>> and then select "Activate levelling system" under >>Activate/deactivate levelling system (without wheel rotation detection)<< and execute the function by pressing "Start" [F8]  .
• All functions (e.g. bleeding/filling) of the PASM control unit are deactivated as soon as the levelling system has been deactivated using the function >>Activate/deactivate levelling system (without wheel rotation detection)<<  .

Information 

• The ATF inspection plug must be closed again at 50°C at the latest.
• Switch off the engine if necessary, let the transmission cool down and repeat the test.

1. Read off the ATF temperature on the PIWIS Tester  while the engine is running.
2. Leave engine running at idle speed.
3. Place oil collection pan underneath.
4. Fill manual metering pump Transmission fluid filler pump set WE 1372  with ATF for the double clutch transmission.
5. Check and top up ATF.
   1. 5.1. When an ATF temperature of 30°C is reached, unscrew the ATF inspection plug.
   2. 5.2. If ATF emerges from the ATF control opening before the ATF temperature has reached 40°C, the ATF level is OK.
   3. 5.3. If no ATF emerges at a temperature of up to 40°C, add ATF using the manual metering pump until ATF emerges.
