sounds like you are in LIMP MODE, not positive and not familiar with non-U.S. spec cars.
1st thing to do is use the search function on this site and try to get as much info as possible.
Usually a Mercedes Benz specialist that is FAMILIAR with transmissions will pull the codes and know the way to go.

First use the SEARCH function at this site, I am certain I have read many posts with this problem and the cure.
