    Hi, as soon as my 456M starts rolling jumps the speedo gauge to 115kph and stays there. When I stop the car the speedo drops down to 0, but as soon as the car moves it goes quickly to 115kph again regardless the real speed (even if this is above 120kph). After a long journey (>200km) is everything OK up to the next cold start.
    Any thoughts?

    Thanks, best regards, Jan

    It’s your speedo. Remove it and have the circuit board resoldered, as there is most likely a bad soldier joint. It cures it in most cases. If not, your speedo will probably require replacing.
