AIR FLOW PUMP/VALVE

2001 BMW 530

Noises problem
2001 BMW 530 6 cyl Two Wheel Drive 146000 miles

When starting up car in the morning, there is a loud sound from from the engine, the sound last for about 1 to 2 mins. The car runs great I think it might be the Air Flow Pump or Valve. It only happens when the car is cold.
