Have you done any work on suspension recently and need to get the tracking realigned? That can throw the angle sensor out.
I had a ABS sensor with bad wire, damaged wire during other work(shorting interm.) that made those lights go on.Probably not yours probl, but just in case..
Have you check the new wss with vcds to check there isn’t still an issue with them, would be rear but obviously still an option that the new items could be faulty
