My C230 Kompressor with 16,000 miles started idling rough at stop and rougher at lowest speed as in taking foot off the brake as car starts forward and than today check engine light came on. Has anyone experienced this ?

 

There should be OBD codes stored as a result of the CE light coming on. I assume you are under warranty so just go to the dealer and have them scan the car. Rough idle is often a misfire caused by problems with engine electrical and/or fuel system.
