just noticed i got a whistling noise under the hood, as i look at the engine it seems to be coming from the the unit top right of where the belt runs, its a black square with a screw cap on the top, its just a constant whitsle

is it possibly the powersteering pump or the water pump

my cars a s reg w202 2ltr auto

im pretty sure thats whats making the noise, just cant identify what the unit is
 
Sounds like the power steering pump.
Make sure there is enough fluid in it.
