What might cause MINI Cooper whining noise?

Whining noises on Your MINI Cooper often vary as the engine runs fast or slow, and they can indicate several different problems. The problems include a failing water pump, a bad power steering pump, low power steering fluid, a failing alternator, or problems with the air-conditioning system. The most common cause for a whining noise is a failing power steering pump. The power steering pump is driven by the belt drive system to pressurize fluid for power-assisted steering.Have You had that experience where Your car felt like it reverted to manual steering This is a clear indication that Your power steering is not working. The power steering pump is among the first components You should check if the steering wheel becomes very difficult to turn.Power steering pumps also have seals that can develop leaks, which then creates a low fluid level. If You suspect a bad power steering pump, consider checking for leaks.
