Steering Column Adjustment Drive Unit: Notes
WARNING: This page does not describe the selected car, but rather 15 other vehicles, including the 2006 BMW 530i, 2006 BMW 525i, 2006 BMW 330xi, 2006 BMW 330i, and 2006 BMW 330Ci. However, it is still accessible from the selected car via links, so may be relevant.
Two motors are built into the drive unit. 1 motor drives the tilt and fore-and-aft adjustment of the steering column. The second motor changes the direction of adjustment via the adjustment gears.
The adjustment movement and position recognition for both tilt and fore-and-aft adjustment are recorded in the drive unit for the steering column memory. There are 2 Hall sensors and 2 magnetic rings (16-pin) integrated in the drive unit.
