Steering Wheel Up/Down Adjustment Not Working




The issue is simply a couple poor adjustments.
No amount of greasing and motor replacement or banging the wheel can replace a quick tweak.
The many TSB repairs released year after year, point at doing additional busy work without adressing the root cause.
Owners incentive is to keep the steering column in working condition because during collision the wheel is repositioned at high-speed by the SRS module. When jammed you may get served a wake-up blow by the Takata airbag.

> For techies :
Have a look at this fix !
This will show you how to adjust smooth mechanism to resolve jamming & clunkyness.
> For non-techies :
-- Disable "convenience entry" using menus
-- Do NOT BANG on the wheel: column module has many fragile solderless electronic assy that are anything but rugged.
Hope this helps further enjoy ownership.

As it's covered by warranty, just get it replaced. If you want to try, use the knob to force it to the highest position (yes, I realize there will not be any apparent movement due to the issue you presented), then take your arm and bang down really hard on the steering wheel. Chances are it'll get it working again...

He did a quick job with only a single item limited to the Tilt motion.
This video is a good way to get into fixing these steering columns.
It's interesting to see how W166 share the same component & same issue & ultimately same fix too.

One case is the steering column getting stuck in its highest position when easy entry/exit is enabled. There is nothing wrong with the function of the motor, it's just jammed, requires a beating and reprogramming.
Mine happened again after the dealer corrected. I simply turned off the easy entry/exit function for now. Have another appointment to resolve.

I used the "smack it like a red headed step-child" approach....and it worked for me.
Held the switch down and gave it a good downward hit.
