The oil pump is inside the oil pan. To take the oil pan off, you may need to raise the engine. Oil pump failures are very rare in a BMW. It may be worth it to go to a dealer and pay the $80/hr for a complete diagnosis. It could be just a bad sensor. If you hear no unusual light tapping from the engine, it could just be the sensor.
