You guys are right, thanks. Steering wheel on the "Options" screen
clearly shows that you are right, thanks.
But, this isn't that easy. 100% drive so beautifully, and this is
the ultimate judge. But, thanks, you are right, somewhere else is the
problem.
Well, I already checked absolutely everything, and the only thing
that is left is the calibration process, which I started to fiddle with.
Here somewhere I must be getting slack.
Thanks again, : ).
