Hello too, yes I know this problem treatment already exists – but mostly older. Have a 451 EZ3/2009 – year 02/2009 approx. 34Tkm (women’s city car). The problem with the brake switch we already had, THAT’s not it! Sometimes – quite often the reverse turn does not go in. It only helps ignition off, 5Sek wait, ignition – goes in. Mostly. Last I had to push it out of the parking gap so that it can drive forward. That’s not funny for a woman and can possibly a I said something about big clutch repair! I’ve already read that there is sometimes a culant control for this “serial error”. What prerequisites must be met? Warranty+extension are of course over. How are the experiences regarding cost frames of such repairs. Here in the country there are hardly any free workshops that dare to do so, except Smart (MB) itself. Thank you for the answer!
