Well, its defo the power steering pump. the noise comes on when I turn the whell and also with slight increase in revs, its sounds exactly like a plastic fan when you drag a piece of card in it.
Fluid level looks a little low actually but no leaks I can see; going to bleed it and see if it improves. I guess not a s bad as the other possibilities.
Complete bollox - add this itssomething to do with the fan belt because a spot of wd40 and its gone. Operating the power steering air con etc made the noise cos of the add on stress to the belt; probably just dry cos it aint loose!
