    Default Electrical fault

    Hello, I have a Smart Roadster Coupe 2005. On occasion all the warning lights come on, engine will stutter, Rev-counter fails, power steering fails, hill start assist fails. The transmission mode and fuel gage disappears and is replaced with flashing bars. The car will not start. Turn off the ignition and leave for 5 to 10 minutes and it will restart and then run fine all systems restored. My Smart has a new SAM unit and new engine all work by Mercides Benz Truro
    Has any one out there experienced anything similar ?

    When ?

    And were the leak problems that undoubtedly caused the SAM replacement sorted too ?

    What you describe is classic symptoms of power supply failure and the systems gradually shutting themselves off.

    Read this topic on the roadster forum for more advice:
