How to Replace the Transmission Fluid for a 2017 Tiguan L?
2 Answers
First, drain all the fluid from the oil pan, then pour in the same amount of new fluid. Next, remove the outlet pipe that connects the transmission to the transmission fluid cooler. Then, attach a long tube to the interface where the outlet pipe was removed. Start the engine, switch between D and R gears, and run for 5 to 10 minutes. While the transmission is pumping out the old fluid, simultaneously add new fluid through the funnel to prevent the transmission from running dry. Finally, remove the tube.
I often help friends change transmission fluid. For the 2017 Tiguan L, you need to lift the car and remove the oil pan guard first. This model usually comes with a DSG dual-clutch transmission, so you’ll need 6-8 liters of OEM-approved G052182A2 transmission fluid. When draining the old fluid by removing the oil pan bolts, you’ll notice a lot of metal shavings, so the built-in filter must be replaced simultaneously—otherwise, the new fluid will get contaminated quickly. After cleaning the sealing surface, replace the gasket and tighten the bolts to the torque specified in the repair manual. Then, use a dedicated fluid filler to add fluid through the side inspection hole. After the change, let the engine idle and shift through each gear to circulate the fluid. Finally, use a diagnostic tool to check the fluid temperature and calibrate the fluid level. This job requires two people to cooperate—doing it alone might lead to missing critical steps.
