Servotronic problem
 

Guys, I'm having some servotronic issues.
When the car and the power steering oil is cold, everything works fine.
When it heats up and I steer when stationary or moving with walking speed, the steering wheel goes and moves to the left effortlessly, as it should. But doesnt't to the right side. It's hard, almost like no servo at all. I pulled the Servotronic relay and bought a new one, that didn't cure the problem. I flushed the power steering fluid twice, no improvement at all.
It's wierd as when the car is cold, everything works fine. Now I have two options, pull the steering rack and do what? As it's bone dry and not leaking a drop... and refurbish it. Or buy a new non-servotronic one, as the Servotronic costs like 1200 EUR. :Confused:
