Strange steering feel A4 2013

[Leggy]

Has anyone experienced problems with steerlng feel. When driving in a straight line I have an intermittent notchy feel. It means I can't make a slight input adjustment.
Actually feels a bit scary.
It had a software update about a year ago for the same.

All I can say is mine has no notchiness but then again no feel whatsoever , lifeless ,

Just a thought you might have a stick track rod end or the like , had a car years ago that exhibited these symptoms and 2 new racks later and the stupid dealer found a seized track rod end !! But I am sure the Audi dealers ability with diagnostics would find that immediately !!
