There's another forum here that is saying that turning DSC off stiffens the steering in comfort mode.

One theory here is that the steering wheel vibration is being caused by the EPS.
I wonder if disabling DSC would reduce the vibration effect by reducing the EPS boost? Has anyone tried that?
I don't have the issue, so I can't tell if it helps or not.
Someone want to volunteer?
