Audi Dual Clutch Transmission Fluid Guide

Are you servicing your modern Audi DSG transmission? If so, understanding the complex fluid locations is incredibly important. Over time, original transmission fluids degrade and lose their protective qualities. Consequently, your expensive dual-clutch system suffers from terrible internal wear. Therefore, you absolutely must perform regular preventative fluid maintenance. Today, we are discussing the 0CJ, 0CK, 0CL, 0DN, and 0DP gearboxes. Furthermore, this quick tech guide explains proper draining and filling procedures. Ultimately, you will service your Audi transmission safely and correctly.

Understanding The ATF Section

First, you must identify the automatic transmission fluid section. This fluid is located within the designated pink section of your transmission. Because of this, it requires specific service steps. You must drain this fluid using the specific ATF drain plug labeled number one. Subsequently, you will refill the system using the ATF filler plug labeled number two. Additionally, open plug A on the drain opening to empty the fluid completely. Remember to close plug A securely immediately after draining. Finally, open plug B on the inspection fill port to add fresh fluid.

Servicing The MTF Gear Oil

Next, you must address the manual transmission fluid section. This gear oil resides within the green section of the transmission assembly. To drain this fluid, you must carefully remove the MTF pump labeled number four. Alternatively, you will fill this section through the MTF check plug labeled number three. Furthermore, there is a specific procedure for the gearbox fluid electrical connections. First, remove the number two electrical connection carefully. Then, remove number one to drain the gear oil completely. After draining, reinstall number one and securely reconnect number two. Finally, open the arrow-marked inspection plug to fill the gear oil.

Crucial Warning For DIY Mechanics

Finally, servicing modern Audi dual-clutch transmissions requires extreme caution. There is a specific bolt located directly on the internal gear set. This bolt is clearly marked with an arrow in factory diagrams. Under no circumstances should you ever remove this specific gear set bolt. Indeed, it is absolutely not a drain plug. Removing it will cause catastrophic internal gearbox damage instantly. As a consequence, you will face massive automotive repair bills. Therefore, always verify your drain plugs carefully before turning any wrenches. In conclusion, service your Audi DSG transmission correctly and drive confidently!
