If nothing worked It would be the brain in the controller for the seat. That one aspect works it's more likely hardware = pricy fix.

Do your seat memory positions still work?

We bought my wife's x5 with defective seat controller board and no memory or steering adjustment until aboit a month ago when I finally put in the replacement controller and all is good.

It's not married to the car : if you have a good friend with e53 you could swap boards in under an hour both ways to confirm (you could also one last time move wheel to the distance you want)

There is a very good chance it's that board. I paid like $30 for mine from an xoutpost member.

Just noticed your location. I go to Chicago regularly it's possible I could do that test if you don't resolve quickly.
