How many liters of transmission oil should be added to a 2015 Passat?

The Volkswagen New Passat requires 4L of transmission oil for replacement. Changing the transmission oil requires professional equipment and related techniques, so it is recommended to have it replaced at an auto repair shop. Below is additional information about the transmission: 1. Replacement: Under normal circumstances, the car's transmission needs to have the automatic transmission oil (for dual-clutch transmissions) replaced every three years or every 60,000 kilometers. The filter should also be replaced; thereafter, it should be replaced every 60,000 kilometers. When replacing the automatic transmission oil, it is important to use specialized equipment to completely remove the old oil and other impurities. 2. Function: Automatic transmission oil has two main functions: transmitting hydraulic power and cleaning and lubricating. It is recommended that car owners replace it regularly. From the perspective of vehicle use and maintenance, regular replacement of transmission oil can make the lubrication and power transmission of the transmission more efficient.
As a long-time Passat owner with over a decade of experience, I remember the 2015 Passat's transmission fluid capacity differs between manual and automatic. For manual transmissions, it takes about 1.8 liters to fill up completely. I've changed it twice myself, and the process is quite straightforward—first drain the old fluid using a lift, then slowly pour in the new fluid. For automatic transmissions, especially the DSG dual-clutch type, it requires around 5.5 liters, significantly more than the manual due to its more complex internal structure and higher fluid circulation needs. Regardless of the type, it's best to change the fluid every 60,000 kilometers to avoid transmission issues. Last time I forgot to change it on time, which led to rough shifting and costly repairs. Now, I always check the manual beforehand to confirm the fluid capacity and ensure driving safety.
