I just got a 2001 330xi and the dsc,abs,brake light stays on and when I got the car the guys said the power steering was not working. I have replaced the power steering pump with a new one and had to replace the pressure side hose to work with the new replacement luk lf20 pump. The power steering seems to works at lower speeds but when the car is at highway speeds the steering is still gets tight? I dont know if the dsc problem has any thing to do with the power steering problem or not can anyone help me out with this?
