SO it makes a noise for about 15mins then goes away??? whoes anyone know what its is? and why it does it?? and how much it might cost to fix ??? aaarrraaagggghhhhh

bearing may be shafted..oil level may be to low..belt slipping.

l am not a saab fan, but l would check fluid level warm/ also check belt tension 1/2 inch deflection or less. good luck

First check oil level and fill the reservoir with recommended oil ( do not mix) if the level is low. Hopefully the noise will go away if there has not been extended usage in this condition. Then check for the leakage, it probably is minor o-ring replacement or a leaking steering hose. Cost depends on the damage.

Check the fluid

Check the fluid level in the reservoir. It explains why in 15 minutes the sound goes away. As things heat up they expand, and then and only then do you have enough pressure to stop the noise.
