hi, I tried to retrofit the electrified steering column on the G31 LCI, the wiring was built according to Tis diagrams, new electric column, button and control unit, obviously code 459 from the BDC, it seems to work but once activated it retracts inwards as if I were holding the button pressed, not even ista can initialize it. 
do you have any ideas for solving it?

If i rmeber correctly there are different buttons for different years. You sure your part is correct ?

I have no idea what help you expect here. NO information what part numbers you've put, no information what faults you have, no information if you looked at live data, NOTHING.

P.S. Isn't 459 electric SEAT adjustment??? No info if you have electric seats... Electric steering column AFAIK is 245.

Thank you for your interest in the discussion, on the G31 series the electric steering column is mounted only in combination with electric seats with 459 or comfort memory, there is no dedicated code 245 as for other vehicles

naturally, full electric seats with memory were installed first and they work perfectly, returning to the problem, Ista notes that the lever to lower it remains pressed, I have already replaced 3 buttons and they all have the same defect, even a couple of replaced ECUs (this it cannot be encoded because it communicates with bdc and szl via lin bus)

Steering column movement must be "normalized" (calibrated) using ISTA. Have you done that???

Normalized finish ok only if disconnected button 
With button connected on szl give error

And You are absolutely sure that wiring is ok?
If You look in ISTA when pushing buttons, are those correct results?

Check wire diagram and all ok, unless there are errors in the diagrams, I can't know that
the movements are all performed correctly, except that in the rest position the steering is positioned completely towards the dashboard and then goes into protection. I'll try to buy yet another button, a new one this time
