thanks for the reply. after we changed the acceleration body sensor(about 150 parts) and bleed the system. The height actually return to near normal. The shop sent the car to alignment. Could anyone tell me what is the height of the car since this can be adjusted. The left is 1/2 lower than the right from the fender flare. is this normal? The alignment shop has no clues.
Also i try to reset the steering angle sensor as per advise. Car has a sharp whining noise upon the steering is turned to the extreme end on both sides. Any comment appreciated.
