What is the oil change method for Volkswagen's wet dual-clutch transmission?
2 Answers
The oil change method for Volkswagen's wet dual-clutch transmission is as follows: 1. Loosen the drain screw at the bottom of the transmission to drain the oil before refilling: When the engine is turned off and the automatic transmission stops working, the oil pump becomes stationary, halting the circulation of the automatic transmission oil. The oil flowing in the valve body, pistons, torque converter, radiator, and cooling lines also stops abruptly, preventing it from returning to the oil pan. 2. Remove the transmission oil pan directly for draining and refilling: This method is more thorough than the previous one, as it removes impurities from the bottom of the oil pan. 3. Use a circulation machine to change the automatic transmission oil: Dynamic oil change with an intelligent circulation machine can filter and clean sludge and impurities inside the automatic transmission through circulation; perform an equal exchange to ensure complete replacement of the old oil inside the transmission, thoroughly clean the internal circulation, and provide the transmission with a good internal working environment, thereby extending its lifespan.
Regarding the oil change method for Volkswagen's wet dual-clutch transmission, I find it quite particular. Generally, the vehicle must first be safely lifted using a stable jack or lift, and gloves should be worn to avoid burns. Then, locate the drain bolt at the bottom of the transmission, gently loosen it with a wrench, and allow the old oil to completely drain out. During this process, the oil temperature should not be too high—wait for the car to cool down before proceeding. After draining, clean the bolt and tighten it back, then locate the fill port and use a specialized oil extraction tool or funnel to add new oil. It is recommended to use VW-approved DSG fluid. After filling, start the engine and let the transmission circulate for a few minutes before checking if the oil level is within the marked range. Don’t forget to replace the filter if required by your model. Remember, changing the oil every 60,000 kilometers can effectively extend the transmission's lifespan. Ensure you have all the necessary tools ready, such as a 17mm wrench and an oil extraction pump. The entire process must be carried out carefully to avoid malfunctions.
