Tire Pressure Sensor: Removal

  1. Raise vehicle on a suitable support. Remove tire/wheel assembly from vehicle.
  2. Dismount tire from wheel. Ensure assembly head for top tire bead is positioned about 15 cm behind valve to prevent damage to wheel electronics. When removing lower tire bead, position assembly head about 5 cm behind valve.
  3. Release and remove the wheel electronics unit from the valve using a Torx socket screwdriver T 20 (counter with a suitable assembly pin if necessary, e.g. steel pin with diameter of approx. 1.8 mm in bore at valve foot) and remove it. The new valve comes with an assembly pin. This can also be used for removing the wheel electronics unit. See Fig 1.
  4. Unscrew union nut and remove valve.
