Limited steer angle on New Holland T6 CANBUS

I am having problems with getting UTurn to work properly on my New Holland T6.175 2018. The tractor has a factory installed auto steer valve and AOG is connected through CANBUS. All calibrations in the tractor menu are done successfully and AOG steers just perfectly on straight lines.

With UTurn, however, I can’t get the wheels turn all the way. Does anybody know if the tractor limits the steer angle when auto steer is enabled? And if so, is this configurable somehow?

When steering into a curve, the wheels only turn roughly 75 % of the maximum. Still AOG reports that the steer angle is at the maximum value set (40 at the moment). When I touch the steering wheel and auto steer disengages, the reported steer angle drops to ~22. And then when I turn the wheels to maximum manually, the angle goes to 35.

While driving manually, the reported steer angles seem just normal, so probably the WAS is working ok.

You did steersettings with wizzard? Could be CPD wrong and/off max steerangle

Yes. I have also tried different CPD settings without luck.
