Hello to all, I have the following problem with my Smart 450 year of construction 2006. In the gears 1-3 a heavy jerk is pressed at full throttle only with accelerator pedals full. With careful operation of the pedal no problems. In the gears 4-6 I have then with full throttle thrust-wise acceleration. As if the turbo times starts and sometimes not. Now the strange thing comes back when I slowly with the gas pedal comes back at some point a point where he pulls through fully when I leave the accelerator pedal on this position he pulls as he should also after gear change but I have to keep exactly the gas pedal position otherwise the whole from the front again. That was already carried out/checked: All spark plugs new all 6 images/forum/smilies/icon_biggrin.gif of course. Wastegate and pressure can tested rods was a bit fixed then they got cleaned up again but still works out of it a little quiet running. Last week I had a small crash but at least before then the memory was read out without having to use this problem. Nevertheless, the same problem still remains quiet again.
