Power steering has rest points, steering step ruckelig hakt

Hello! It’s about the power steering on the small one. Who also has the problem that soft rest points can be felt with slow steering wheel movements? One could also say that the steering wheel runs in a step, ruckle, hooked or sticky lightly. Especially at higher speed on straight distances a really annoying problem. If you want to make slight steering corrections, you have to overcome a small mechanical resistance each time, so that the steering at the next rest point “catches”. Straight ahead is almost impossible, because you have to move the steering wheel constantly between two rest points. You always drive a slight line of snakes, so to speak. This soft griding occurs more strongly after some driving time and is then noticeable even with standing vehicle, if you move the steering wheel very slowly. In daily city traffic it is not so noticeable, because you have there much higher steering strokes. The friendly person felt it himself, but otherwise remains a clue If someone knows a TPI number, is there a field action or a software update for the power steering? Whether VW Up, Seat Mii or Skoda Citigo.
