That air pump, the one to the left hand side, top of the engine bay conected to the pully system, right by the induction, what does it do? does it operate the heater directional system?

It pumps air into the catalyst to help reduce bad emissions.

Its used to add air to the exhaust gasses. This lowers the emmissions at idle ( I think )

Great, cheers guys, someone had disconected it because it had a noisy bearing, glad to hear it\'s nothing that important, although our planet is important.
