How do I check my engine oil level on an Audi A4?

I recently purchased a used Audi A4 and I want to make sure the engine oil level is optimal for the car's performance. Can anyone provide a step-by-step guide on how to check the engine oil level?

To check your engine oil level on an Audi A4, first make sure the car is on a level surface and the engine is off. Locate the engine oil dipstick, it's usually labeled with a yellow handle. Remove the dipstick, wipe it clean, then reinsert it and pull it out again. The oil level should be between the minimum and maximum marks on the dipstick.
