Where is the transmission oil filler port located on the Audi A6?
2 Answers
The transmission oil filler port on the Audi A6 is located underneath the transmission, where there are two screw-sealed holes, serving as the drain hole and the filler hole respectively. The function of transmission oil is to keep the shifting system clean and to lubricate the transmission components, thereby extending their lifespan. The Audi A6 is equipped with a 2.0T inline 4-cylinder turbocharged engine, delivering a maximum horsepower of 190 PS, a maximum torque of 220 Nm, and a maximum power of 140 kW. It is paired with an 8-speed automatic transmission. The Audi A6 is classified as a compact car, with body dimensions of 5012 mm in length, 1855 mm in width, and 1485 mm in height. It has a wheelbase of 2922 mm, a minimum ground clearance of 116 mm, a curb weight of 1800 kg, and a fuel tank capacity of 80 liters.
I've been repairing Audi cars for many years, and the location of the transmission filler port varies depending on the year and model. It's generally on the transmission housing, mostly on the left side or at the bottom. For example, the transmission filler port on the older A6 (C6) is on the inner side of the left front wheel, and you need to remove the underbody panel to see the hole with the hex socket screw. The filler port on the newer A8L might be next to the oil pan, requiring a special tool to open it. In actual operation, you have to lift the car, remove the underbody panel, and look for the screw marked with the gear oil icon. If you're doing it yourself, remember this: the filler port and the overflow hole are separate. After adding oil, you must start the engine to circulate and check the oil level, otherwise overfilling can cause excessive transmission pressure.
