Hi. Bought this beautiful car and it had a dealer buyback history. I pulled codes with my fuxwell 510 and showed steering angle sensor error. So replaced it w a new bmw unit and it wouldn***8217;t accept my calibration. Still showing the trifecta of lights and goes into limp mode at highway speeds occasionally. Brought it to an Indy beat here and they are unable to calibrate it either I don***8217;t have detailed records on why it was a lemon so that doesn***8217;t help. What other issues can prevent steering angle calibration and limp mode. Replace a wheel speed sensors last week. Any help would be appreciative. Who is the best Indy bmw guru in Austin area?
