New steering wheel now brings up "Lane keeping Assist Inoperative"




I'm assuming you bought and installed a complete steering wheel.
If you're lucky, your steering wheel has this "Lane Keeping Assist" installed and you just forgot to plug into the steering wheel control unit. (2-pin plug, top / right) Remove the airbag and you will see this.
If you're unlucky, the "Lane Keeping Assist" (a "vibration motor") isn't built into your new steering wheel.
This part is permanently installed on the GT 190 steering wheel with "Lane Keeping Assist" and cannot be replaced or retrofitted.
(There are also bigger MB steering wheels where you can swap this motor unit)
Unfortunately, your only options are to replace the steering wheel with the right one, or code out the “Lane Keeping Assist”.
This means delete code: 22P
But now activate code: 234 at the same time.
Otherwise you will also lose the “blind spot assist”. (mirror triangles)
To complete:
Current MB steering wheels no longer have this “vibration”. Here the vibration (or counter-steered) is generated via the electric power steering.
GT190 is one of the last MBs with hydraulic power steering.
