Fully understand.

My car still does the random neutral thing despite reprogramming. Similar to yours. See video.
Dealer unable to fix.

Did you try a different dealership? Some dealership is just better than others in terms of their technician, services etc. in my experience.

There was an absolute master mechanic that initially worked on the trans issues. He has since been poached by a new electric car company.
The current tech seems able to get the trans info off the car. They are working on it with support in Germany. Keep you posted.

The dealer has been pretty good actually. It is not the same one as where I purchased. They were useless.

In the end, Merc corp makes all the decisions and tells the dealership what to do. We'll see.

I thought this would happen to me but it never did.. some times it would not start right away but it does even if it is 2 seconds.

Because I have never heard of this, I hope MB can help you.

Sounds like you are actually in good hands, looking forward to an update.

After repeated visits, video of the situation and them replacing the torque converter (yes, the trans was pulled out), they have finally decided to replace the transmission on my C43.

I think there is an issue out there with these 9 speeds. Seems to be reported here and there in other models.
