How do I change the oil in an Audi A4 3.0 TDI?

I have recently purchased an Audi A4 3.0 TDI and I am unsure of how to change the oil. Can someone provide me with the steps to do this properly?

Changing the oil in your Audi A4 is a simple process that you can do yourself. First, you will need to gather the necessary tools and equipment, including a new oil filter, oil drip pan, and a wrench. Next, locate the oil drain plug under the car and place the oil drip pan underneath to catch the old oil. Once the old oil has drained, replace the oil filter and refill the engine with the recommended oil. Finally, dispose of the old oil properly. If you are unsure of the process, it is always best to consult your owner's manual or visit a certified mechanic.
