E65 Steering Wheel buttons stopped working & Airbag error

[csatu]

Hey guyz!
All of my steering buttons stopped working.(The horn stopped working too,lights on the steering buttons gone too), and i got an airbag restraint system error.

Theres my error codes from SGM airbag module:
93D9 Abschalten von Modul 3 (SZL E65, TEFAT E6X) (Switch off by Module 3, SZL E65)
9446 Pre-Drive-Check n.i.0. wegen Modul 3 (SZL E65, TEFAT E6X) (Pre-drive check not ok. because of module 3)

And my SZL module stores these errors:
94EA Kommunikation zwischen Lenkrad und Lenksaeule fehlerhaft (Communication between steering wheel and steering column fault)
951A Spannungsueberwachung LRE unterer Grenzwert unterschritten (Voltage monitoring LRE below the lower limit)
9518 Spannungsueberwachung ASE unterer Grenzwert unterschritten (Voltage monitoring ASE below the lower limit)
94E3 Klemme U_Isis fehlt (Terminal U_Isis is missing)

This can be a broken steering column cable or clockspring?
I think not my SGM module cause the error(or I might be wrong)

Thank you for help

Same happened to me... Long before the steering wheel buttons and restraint faults my heated steering wheel was out too.

This what I found:




Thank god I had new clock spring already so I just replaced it and cleared the codes and everything has been working ever since. I bought a cheap one from china for testing purposes and it's over half a year and still good. I think it cost around 25-27USD.
