Sorry if the question was already here but I couldn’t find anything. I am in despair because of the diesel prices bought me a Smart 450 cdi Bj. 2005 to drive to work. Daily 110km To first everything was tip top and then it went off. From now on he jumped on straight away and the starter doesn’t turn either. So he still recognizes the gears N or R or A or 1. I was then towed by the ADAC to the workshop that had already had to. Next day I went to the workshop and he jumped without further ado. 5 days later the same again. One day waited and he jumped again. 5 days later again again again. Did he have a few meters close to 100 meters it then tried again no reaction. Next day he jumped again. The whole thing happened at all temperatures no matter whether icecold or warm engine. Has here perhaps an idea about that could lie? Thanks for any help.
