Steering Column: Notes
The steering column adjustment range has been extended plus the new adjustment unit now supports the airbag and the steering column. An integrated crash element (metal tube) located in the upper area of the steering column are designed as load bearing parts.
The metal tube is pre-perforated in a defined longitudinal area at the upper end of the steering column. In the event of an impact, this metal tube begins to crack at the predefined points. This perforation is required for the purpose of converting energy in the event of an impact.
The steering spindle sleeve or collar is also new. On the E46, this collar was held in position by the pedal assembly. The new collar is connected in the bulkhead and is doublesided, which results in a lower reset force for the steering column height adjustment.
Together with the Electric Steering Lock (ELV) System, the steering column forms one component and may only be replaced as a complete unit.
