The oil dipstick on a 1997 BMW 528i is located on the left side of the engine. It has a tube which connects to the engine block and directs the dipstick into the bottom of the oil pan.
The oil on a BMW Z4 is changed by putting a oil drain pan under the engine, placing the vehicle on jack stands, and removing the oil drain plug. The oil is then allowed to drain, the plug re-installed, and the engine filled with oil.
