Volvo Air Pump -

Does the Air Pump (SAS) Really Do Anything?

My airpump has started to sound like a vacuum grinding up a cat. Of course, the noise only lasts a minute or so, then it stops and all is well. I guess I have 2 questions:

1. What does the air pump do?

I ask this because the car runs no different before the thing kicks in and no different after it shuts off.

2. If nothing changes regardless of this thing being on or off, do I actually need it? Can is be simply unplugged and ignored?

Some people may gasp and sputter at that last statement, this is an honest question looking for a direct answer…
