Have you tried rebooting the autopilot (i.e turn off and then on again)?

We had it happen to us that the autopilot did a doughnut (360 deg turn) in the middle of the gulfstream under sail at 25 kts of wind - a bit scary.

Once I got the boat under control the autopilot indicated that we were on a course of 90 deg while I was heading due west towards Florida.

M resourceful wife solved the problem by turning of the autopilot for 5 secs and then turning it on again. Worked a charm and never had problem since.

Also check for big pieces of metal objects that you may have placed close to the aitopilot compass unit...
