[OLeonardo]

Volkswagen's dry dual-clutch transmission requires gear oil replacement, and the replacement method is as follows: 1. Locate and remove the odometer shaft cover, then pull out the plastic small gear; 2. Unscrew the gear oil drain plug of the transmission, drain all the gear oil, and then tighten the drain plug; 3. Add gear oil through the odometer shaft hole, ensuring the oil level does not exceed the F-line; 4. Reinstall the gear. The functions of gear oil include: 1. Alleviating engine friction and high temperatures; 2. Reducing gas leakage and preventing external contaminants; 3. Protecting components from contact with water, air, and harmful acidic gases; 4. Buffering the pressure at the engine cylinder port; 5. Cleaning dirt from component surfaces.
