5. Remove the steering column switch assembly (see subsection above).
6. With the steering column in the central position, gently press the locks (arrows in the illustration) and separate the coil spring (2) with the angle sensor (1) from the steering column switch unit.
8.6. Removing the coil spring with the sensor.
7. Remove the bolts (see illustration) and remove the steering column electronics control unit (1) from the steering column switch assembly.
8.7. Fastening the steering column electronic control unit.
8. Installation is carried out in reverse order. After replacing the control unit, it should be recoded using a diagnostic tool (see chapter 5).
