Summary
Complaint: Height adjustment of electric steering column adjustment jams in upper / lower adjustment position or it generates a cracking noise when exiting the upper /lower adjustment position (e.g. for Easy Entry function). Cause: Height adjustment runs into upper / lower limit stop and jams there or generates a breakaway cracking noise when exiting the jammed limit stop. Remedy: 1.

Commission driver's seat control unit. While doing so, - the control unit software is updated, if necessary - the limit stops are cleared and normalized again - and any renewed jamming is prevented 4. Once commissioning has been completed the vehicle can be handed over to the customer.
