I am getting a pulsing sound, sort of like a fan slowing down then speeding up (not a brillaint description I know) coming from what seems to be the power steering when I turn the wheels.
I very rarely happens in the morning, but when I am parking the car at night it is nearly always there. It doesn't appear to be doing it during normal driving, but I am not sure whether it is the engine drowning the noise.
A garage recently checked the steering rack/column and it briefly disappeared
Any ideas?
