How Do I Check the Oil in a BMW 540i?

1. Park your BMW 540i on a level surface. Allow the engine to idle for a few minutes then turn it off. Wait five minutes then raise the hood of the car.
2. Pull the engine oil dipstick out of the tube. The dipstick is in the center of the engine compartment with a small plastic loop on top. Wipe the dipstick clean with a paper towel.
3. Insert the dipstick into the tube until it is seated completely. Pull the dipstick straight out and examine the oil level compared to the markings on the stick. Add oil if it is at or below the 'Add' line.
