Does anyone happen to know the part number for the clock spring on the 2010 e350 sedan?
thank you

What happened to yours ???

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 ?

thanks man - well I didn’t didn’t need a new spring because all I did was change the steering wheel (which doesn’t require a new spring). Now I lost connection, which may or may not be related to the spring. Ahhh, yes I did scan it last night and got code U100800

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.

no this wheel was plug and play. It was coded to work with the older model.

By your admission let me praise how cool the new steering wheel looks good on te W212
Great job, I had also replaced my steering wheel to AMG too
Great job
Sorry for intrusion

thank you - Also, does anyone know for sure that if a clock spring is broken will the SRS error message come up in the instrument cluster those throwing an error code for the airbag? I do not have any error messages or codes related to the airbag. So I am thinking the clock spring may be ok and the issue is within the electronic connectors in the
Steering wheel. Also, another sign of a broken clock spring is a rubbing noise come from the steering wheel. Mine is silent.

What do you mean you lost connection? As in you cannot access the SCM?

I would contact whomever did your coding...

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.
