PS Pump Noise when cold ???
I've noticed a whining noise from under the bonnet when the car is first started in the morning, cold start and turning the steering wheel sounds horrid... could this be air in the fluid? There is no fluid loss that I can see, but the hose on the bottom of the fluid resevoir has fluid over it, so potentially needs new clamps on?
Or could it be something worse like bearings/pump gears etc?
The noise goes away when warm and been running for a bit.
Anyone experienced anything similar?
