Meals together, I’m new here in the forum and despair so slowly. I have a Smart 451 2010 MHD and this one is now really worrying me. To the problem: Regularly jumps out during the drive the gear or unplugs the car simply off or occasionally it just stays stuck in some gear and switches neither up nor down. What I have done up to now: New clutch + actuator, cable and plug checked, mass connections checked, gears learned (unfortunately not with Star diagnosis). When all this did not work out, I got an accident and exchanged further parts: GSG, gear, partly cable tree etc.! Also the battery is new but still it always hits this error again and again… Does someone have a similar problem or a tip or idea for me? Ideally it would be if someone from the area Dortmund/Unna could help me. Maybe someone near a Star Diagnosis device!? I’m curious about your answers and would really be happy about help! Currently no errors filed in the STG but then P08 is always present and sometimes there too.
