The programming options (Version coding) between US and EU
cars varies. Some of the options they can activate like speed limiters (LIM), warning chimes, and other functions are un-available to us due to our USA licensed Diagnostic Computers.
Sometimes as a model gets a year or two old, the programming options increase for that model as we update our machines monthly.
When your 55 goes in for it's first visit, maybe the tech can check for you to see if it can be done. I would ask for a Foreman however.
Enjoy your new car. They really are a kick in the pants!
