hallihallo smartgemeinde, I already found out for my smart cdi bj 2010 the second time that he suddenly no longer took gas and became slower and slower. the latter time on the autobahn, where I drove full throttle and all of a sudden the power from now on was no longer given. suddenly the tachopin went back from 150 to approx. 90 km/h. if you pick up, restarts, runs again perfectly. can someone dissolve this rattle?? what can that be??
