Already scanned, no codes.

A basic OBDII scan won't show problems on the canbus, if there are any. Not sure what scanner you're using, but when I got a Smart at the start of the year that's all I had and I did not find it sufficient. When I got a more capable scanner, I was able to locate my issue as a problem with the shift motors. Not suggesting that's your problem, but if you've got a basic OBDII tool, it's probably not going to read much beyond basic engine controls.
