at about 1500rpm I am getting a strange squeal sometimes, its coming from the engine and sounds like its coming from the passenger side but its hard to pinpoint, above and below 1500rpm it is not present

 

after about 5 minutes of driving it goes away and doesn't appear until the next day,

 

any ideas what this could be? I only notice it because my coolant sensor plays up sometimes and it idles at 1500rpm

What type of squeal, metallic or perhaps more like a drive belt ?

Im not sure really it doesn't sound like a metalic grating and it goes after a while, but it doesnt sound like a belt,

 

it is basically at 1500rpm and only then, if i didn't idle at 1500rpm sometimes I wouldnt even notice it

 

it wouldn't be a turbo bearing at 1500rpm would it?

Belts can make a horrid noise sometimes. As it's just when it's cold then I would expect that one of the belts is a reasonable possibility. Try checking the tension of them all.
