How can I change the oil on my Audi A4?

I've never done it before and I'm not sure where to start. Any tips?

First, make sure you have all the necessary tools and supplies, like a wrench, oil filter, and fresh oil. Then, locate the oil drain plug under your car and place a drain pan underneath it. After draining the old oil, replace the oil filter and refill the engine with new oil. Always consult your owner's manual for specific instructions and recommended oil type.
