How to change oil in Audi A4?

I recently bought an Audi A4 and I have no idea how to change the oil. Can anyone give me some advice or tips on how to do it properly?

First, make sure your Audi A4 is on a flat surface and the engine is cool. Then, locate the oil drain plug and use a wrench to loosen it. Place a drain pan underneath the plug to catch the old oil. Once the oil has drained, replace the plug and fill the engine with new oil. It's also a good idea to replace the oil filter while you're at it. For detailed instructions, consult your Audi A4's owner's manual.
