Steps:
Draining old oil from the radiator:
1. Place the car on a level surface.
2. Run the engine for a few minutes to warm up the transmission oil and ensure better fluidity.
3. Turn off the engine.
4. Remove the engine protection (if equipped).
5. Find the automatic transmission pan.
6. Clean the area around the automatic transmission pan drain plug.
7. Place a container to drain the old oil under the drain plug.
8. Carefully unscrew the drain plug and drain the old oil into a prepared container.
Replacing the automatic transmission filter:
1. After all the old oil has been drained, clean the automatic transmission pan and replace the O-ring of the drain plug.
2. Unscrew the bolts of the automatic transmission pan and carefully remove it.
3. Remove the old automatic transmission oil filter.
4. Install the new oil filter and make sure it fits snugly.
Filling new oil with radiator:
1. If you do not have an oil change machine, return the automatic transmission pan to its place and tighten the bolts.
2. Find the connection between the radiator cooling line and the automatic transmission. Usually these are two thin lines going to the radiator.
3. Loosen both connections on the radiator and drain the old oil into a prepared container.
4. Using a funnel, pour new oil into the automatic transmission through the filler plug.
5. Tighten the filler plug.
6. Connect the radiator hoses to the automatic transmission and tighten them.
Oil change machine:
1. If you have an automatic transmission oil changer, follow the instructions included with the equipment.
2. Connect the device to the automatic transmission through radiator pipes or other provided ports.
3. The machine will circulate the old oil and replace it with new oil.
Checking the oil level:
1. Start the engine and let it idle for a few minutes.
2. Shift the gear selector through all positions and return it to Park (P).
3. Check the automatic transmission oil level using a dipstick or through the inspection window (if equipped).
4. The oil level should be between the “Min” and “Max” marks on the dipstick or within the visible range in the control window.
5. Add or drain oil as needed to achieve correct level.
Resetting the oil change counter:
Many Audi models have an automatic transmission oil change counter. After changing the oil, you must reset this counter so that it displays the correct information. The reset process may vary depending on the vehicle model. Refer to your vehicle’s owner’s manual for exact instructions.
