I have a noisy VCW Sine TCW Vaillant Combi Boiler after bleeding the rads?

I bled 2 upstairs radiators which were cold at the top and let out quite a bit of air but having done so, the boiler now has a whining noise which I suppose is air related. Any ideas how to remove the noise. The pressure is also lower at about 0.5bar now..
