Steering Groan

[Paul72]

Hi i have a 2005 e53 x5 , recently ive been getting a decent groan from the engine bay , it is definately connected to the power steering because it gives me different pitches of sound when wheel is turned one way then the other , power steering seems to be working and noise goes after a while but always there in mornings , !Removed! neighbour actually commented " that sounds expensive " cheek ha can anyone help !!!!??

I take it the fluid level is correct? Does it feel heavier when it is noisy?

[Paul72]

No its ok diesnt go heavy at all . Looks like level is half way but not sure where level should be because doesnt seam to have any level indicator . I can put finger in its about an 1.5" from bottom of res .

The cap has its own dip stick with level marks that you should be reading. Half way sounds low I would check for any sign of leaks, noises can be caused by air in the system if topping up makes sure you use the correct fluid. Moving the steering lock to lock will bleed the system.
