How do you change the oil in an 2012 Audi a4?

To change the oil in a 2012 Audi A4, first ensure the engine is warm, then turn it off and let it cool briefly. Raise the vehicle and secure it on jack stands. Remove the oil drain plug under the engine and let the old oil drain completely, then replace the plug. Next, remove the old oil filter using an oil filter wrench, apply a bit of new oil to the gasket of the new filter, install it, and refill the engine with the appropriate type and amount of new oil through the oil filler cap. Finally, run the engine briefly to circulate the oil, check for leaks, and verify the oil level with the dipstick.
