Need some advice. I recently had a wiper stalk replaced and after that I am getting 2 messages. 1. Speedtronic visit workshop 2. ESP faulty. Garage I used tried resetting and erasing the messages but he said it is not going. Then he said probably there could be problem with steering angle sensor!! It was all fine before he changed the wiper stalk. Any idea what could he has done? I have driven the car and it works fine. I have not tried using the cruise the control.
