220 clc diesel. When cold power steering is fine, when car

This answer was rated:

220 clc diesel. When cold power steering is fine, when car is warm at very low speed steering very stiff, but will suddenly become easy again then stiff again. Stationary at 800 rmp steering ok, ref to 1200 and it becomes stiff. Any idea?
Stan :

The steering rack on CLC has a speed-sensitive power steering valve, which is meant to reduce power assistance at higher speeds for better handling. It seems to be failing in this case. The valve can be replaced separately from the steering rack.
