Center Command Knob not aligned
Hello, I have a 2010 Mercedes E550. Recently the common issue of where the Center Command Knob shaft breaks. I went on ebay and purchased a new aluminum shaft to replace the crappy plastic OEM shaft. After doing the installation/replacement it works fine. But after using the knob for a bit (rotating left and right) and I noticed when you turn the wheel you feel the click, but command doesn't respond until you turn until the click then slightly rotate another centimeter or 2 before the command responds such as going to the next song. It only happens if you rotate clockwise. Sometimes the command changes on the click for a brief amount of time then it slowly reverts back to the turn to click then continue turning which has become extremely annoying. I know Im not the best at explaining things but basically its, my command knob doesn't respond on the rotating click, its out of alignment or sync.

I did this fix myself a few weeks ago on a C350. I can think of a couple things.
After replacing the shaft the knob slots into the top of it and screws in. I doubt that this is the problem but it would be an easy(ish) check to make sure that was installed right.
Maybe more likely is a pinched wire? That ribbon wire was extremely delicate. I don’t know about an E series but the console on the C was over the wire and required me to cut it and splice back together after getting out. There was a lot of stress on the wire to the point of breaking it right next to the unit when pulling it out too.
A good test test would be to remove the trim and pull the unit out again while still connected. This would be a 5min job on a C so I hope it is easy for you. Then use it while moving the wire around at different angles. See if it has a pinch in it somewhere.
Did you do the repair yourself?
