Kobelt steering gear rudder found hunting between 5 degrees P and 5 degrees S with period 2 seconds. This happens only underway sailing 5 knots and more. All terminals checked for tightening, all feedback linkages checked and found ok. Any ideas?

I think incorrect adjustment on servo control board. Re adjust on the Auto pilot Servo control board . we have the same problem. in my case this adjustment is not stated in the manual

This trouble related to internal leakages inside of steering gear hydraulic control unit. First of all inspect check valves (2 pcs) for wear, broken springs etc.
