C55 All Steering Wheel Buttons Not Working!
(C55 AMG) So I had an ESP malfunction, did a diagnostic, and replaced the steering angle sensor assembly. The ESP issue is now fixed, except now none of the steering wheel buttons work! This includes all front buttons on the wheel, the "paddle" shifters, and the reset button on the left side. My code reader pulled these codes for the SCM: 9346, 9359, (also 9358 but that's unrelated [windshield washer inoperative]). Really stuck here as don't have much Merc experience and couldn't find much out there. Really hoping to DIY this as I don't want to take it to the stealership.
TIA

Any update on this?
I bought a 2003 E55 and both shift buttons on the rear of the steering wheel don't work. All other buttons work as expected. I can also shift manually using the gear selected as expected.
