Yes MBDoc the SRS light was on as well as the ESP.

I had all steering wheel functions before I did the work. NOW nothing, I also thought is was the clock spring as I have tried two others straight from Mercedes thinking I could have gotten a faulty part. The steering wheel hookups come straight from the clock spring. I just don't understand what could be going wrong. The description on the clock spring where it tells you to turn it all the way to the left then two full turns to the right to line up the arrows. I don't see how I could be doing that wrong but could that cause my issue? Also do you happen to know if there is a fuse for steering wheel controls and horn? Or possibly a relay.....? Also could this yaw sensor have an affect on issues Im having? Thanks alot guys
