Steering Failed problems of the 2014 Mercedes Benz C250

The airbag light came on. Dash board displays left airbag malfunction, horn no longer works, display can not be cleared. Steering make lots of of clicking sound when turned on either direction. Took the car to the mercedes dealership for diagnosis. The initial response was that the steering module failed and my assessment was it is probably due to recall no ground wire recall number 17v627000. . Upon further inquiry the dealer told me that the steering module broke and came apart. I suspect this either due to defective steering module or recall # 17v252000 steering bolt. I had communicated this issue to mbusa via emails and several phone calls. They still haven't agreed to cover the cost of the repair. After several calls to the dealer, they finally shared the picture of the steering module as you can see it attached. Other owners have reported the same problem. Please see picture of installed and new module.
