My W203 C240 Estate has developed a random ignition problem over the last coupe of weeks. Sometimes the engine does not start, ignition lights will come on in Position 1 & 2 but nothing happens when I turn to start the engine. Engine does not crank. It will not start for 6 or 7 times then randomly start. Have looked at threads on here and tried having foot on footbrake or headlights switched on, this seems to help but not all the time. Have also now noticed that if dash is in Trip Computer mode when I turn to position 2 if the Miles/Duration/Speed/MPG digits stay displayed the car will start. But if I turn to Position 2 and the digits arent displayed but just dashs in those fields the engine wont start.
