Noisy Baxi105e

I have a Baxi105e that is making a noise when the pre-heat is in oporation. It sounds like there is air inside the pump. Otherwise, everything is working ok, including the hot water and heating.
I thought there was an auto-bleed somewhere. If there is, its not working. Can I sort this myself or do I need a fitter?

there is an auto vent on top of the pump usually screwed down
Noise on the instants on pre heat was usually a whistling sound associated with the divertor valve

No, its not a whistle sound. Its sounds like air curculating through the pump. I haven't had the casing off yet but when I do I;ll look for that auto vent on the pump.
