Autopilot slow roll in flight

[Remy]

Hello
Sometimes in flight my autopilot seems to make a light roll right and left ( dutch roll?)
Any idea?

Thanks

This is from the Dynon autopilot tuning guide, a worthwhile thing to carry out if you haven't already.

It will really make a difference to how well the AP performs.
