Hello dear people, for about a week we have a smart 450 petrol truck for the work path. After initial difficulties, because the previous owner neglected the service and the car ran like on only one cylinder I changed the candles, cables, oil and filter and now it runs again very clean and calm. However, the turbo worries me because the rod after the valve was totally rusted, I removed the exhaust and looked for the problem. The rod can no longer be moved, the cracker has a hair crack, the turbo loader does not run with and the small “shovel” in the cracker is broken, see photo. In addition, I noticed that the tiptronic switching operations are unfortunately anything but gentle, probes are more beaten in. Can someone help what I can do and if I can drive with the broken shovel in the cracker so?
