Hello, I want to make myself clear here whether someone has the same problem (only found it once here in the forum). I have the new Smart (model year 2010) for three weeks and have now about 750km down. First two weeks everything ran perfectly, after that however, the car began to vibrate more and more when it is warm. Listens or fills up then, as if I was speeding up all the time low-touring (with short driving time only easy to take, but always gets stronger). If he stood overnight, however, sounds the first 5 min. drive everything as I picked him up. Did now bring him to Smart and get the statement, that would be normal with this model and would come from the gearbox. That would be so with everyone. (???) So, now to all, who also have the 84ps Smart, you really have this problem and do not bother you at all??? Especially when collecting everything perfectly ran???????
