  Q: How to service and replace the steering angle sensor, ride height sensor on BMW Z4?

  A:

  DSC comes as standard across the range together with ABS and Traction control The main aspects of DSC are Cornering Brake Control (CBC). This system measures the movements of the steering wheel, the suspension ride heights, the road speed and the lateral acceleration which controlling the brake line pressure at each caliper when applying the brakes to avoid understeer or oversteer. The replacement of the steering angle sensor can only be done if the complete Steering Column is dismantled, which is best left to an authorized BMW dealer or specialist as it needs a steering angle offset procedure after that, which requires special diagnostic equipment. The front ride height sensor is the control rod which has the nut removed, the retaining screws pulled out and the electrical connector disconnected during removal; during installation the process is reversed and a headlight alignment check is performed. The DSC control unit which is integrated with the ABS control unit must also be replaced by a dealer or specialist. Whenever the DSC pre-boost pump is replaced, the brake high pressure hydraulic system has to be flushed or bled by using the right equipment. They are found preferably beneath the brake master cylinder, and this means that the supply hose has to be clamped and disconnected with special attention in case of splattering of the fluid. The lateral acceleration sensor is located under the driver seat, therefore the driver seat has to be taken out and then penetrate the floor panel, shift the insulating wedge. Finally there are three screws which need to be undone at the back to unlock the sensor bracket and with gentle pulling the complete assembly can be drawn out from the front - extra care has to be taken while handling the sensor as it moves very sensitive to any form of vibration. If necessary, loosen and disassemble the sensor from bracket and overall procedure of installation is similar to the removal procedure; however, should there be fasteners, these should be tightened to their respective manufacture's torque specification.
