it may be broken, but not sure yet. I need to do a little more digging. I upgraded my steering wheel 3 weeks ago. Now suddenly, I have no electrical power the the steering wheel. None of the buttons on the steering work no, horn doesn’t work, paddle shifters don’t work, backlight in the wheel doesn’t work. The wheel worked perfect the first few weeks. So I am not sure if it’s the electronics on the new wheel or not. If the wheel itself is fine then it must be the clock spring (unless there is a fuse somewhere just for the steering wheel electronics).

That new sport wheel really looks good in there ✌️
- Did you follow a specific procedure to index you spring. If not... then that would explain loss of connections.
Have you checked the live data with a scanner ?

Does your scanner do bi-directional?
I thought when you go to a newer wheel, you must use the steering column module (clock spring, turn signal/shifter/cruise/distronic/column adjust stalks) from the newer model and make sure it has all the same features as your old one.

Steering wheel. Also, another sign of a broken clock spring is a rubbing noise come from the steering wheel. Mine is silent.

Live-data and bi-directional control would give you insight into whether its a issue with the wheel and/or SCM. Without that the best you can do is continuity between SCM and and power/ground checks for the SCM (unlikely if all your other controls work, i.e. turn signal, shifter).

W212 wheels don't have a module (signals are passed thru clock spring into SCM, which is all one unit), these newer ones I'm not familiar with.
