I own a 2000 C230 Kompressor. I have the same problem. I have replaced the switch 2 weeks ago and the lights went away. That is until this past monday. Now they are constantly on. Cruse control works but at times the trans goes into limp mode. I have to re-start the car and all is well with the exception of the lights. Battery is fine alternator is fine grounds are fine. So, is there a posibility that the new switch may have gone bad that quick? Should I try another one? Any sugestions would be apreciated.
