How Many Liters of Transmission Fluid Should Be Added to the Volkswagen Tiguan?

[DiSara]

For the Volkswagen Tiguan, approximately 4 to 5 liters of transmission fluid should be added, depending on whether the transmission oil pan is disassembled or just a simple fluid change is performed. Below are the methods for changing transmission fluid: 1. Gravity Drain: The principle is similar to changing engine oil. Loosen the nut with a tool, and the transmission fluid will automatically drain under gravity. Although this method is simple, it cannot completely remove all the old fluid. Residual fluid tends to remain in uneven or hard-to-reach areas. 2. Machine Flush: New transmission fluid is stored in the machine, and the machine's pipes are connected to the transmission's fluid lines. Under hydraulic pressure, the new fluid pushes out the old fluid. This method cleans the fluid lines more thoroughly. The more new fluid used, the cleaner the result. A machine flush typically requires about 10-13 liters of transmission fluid and takes approximately 1 hour. 3. Oil Pan Removal and Fluid Change: This method cleans the transmission from the root, providing a more thorough cleaning, and also allows for cleaning the transmission fluid filter. However, the disassembly process is more complex, and most 4S shops are reluctant to spend the extra effort required for this method.
