I tried another sensor (SRF-02) which also returns sporadically wrong values but not so often.
I have one room, where both sensors are totally unuseable. This room is under the roof with one diagonal wall. I assume that the echoes in this room cannot be compensated properly.

The Differential pilot is one of the most commonly used classes in leJOS, I'm pretty sure that it works correctly. What about things like the floor surface are the wheels slipping? Does your robot have some sort of castor wheel is this dragging and causing the robot not to turn correctly...
