The 5 errors greeting come back this morning also for me.
I got a software upgrade to latest version and reset of some components from dealer 2 weeks ago. Seems that the procedure didn't solve the problem, only avoided them for a while.
Personally, I prefer not having the full steering rack changed, or the car overhauled. For my experience in previous car (not VW), I prefer to keep the car as far as I can from workshop, and keep interventions at minimum possible. I don't want to enter in a spiral of new faults caused by workshop.
For the time being, my VW experience is not so great, as the new car has come to workshop more times than the older one in same previous period...
