What is this secondary air pump for, what does it do?
I have a slight whine on mine, that I've always put down to the PAS reservoir being so hidden as to not get checked during regular services. (I make certain that they check it, but the former owner will not have). Perhaps this is the thing that's causing it. D3 S8
