Grinding ring

Moin, I’m back and with a new problem, since I’ve been having the problem for a long time with the errors of airbag resistance value too large and steering angle sensor defect, I now come to my question my grinding ring(part number: 6N0959654A) is over and a new part is relatively expensive, because I know that you can’t talk about the installation and building of such things here, my question is whether someone knows a cost-effective alternative, such as someone who has one over and possibly gives it off cheaply or someone who can repair this grinding ring for less than 200 €, I would be very grateful.
