Engine not starting, engine still clicking after trying to start engine
your help is greatly appreciated...thanks.
Does the engine try to turn over or is there just the clicking from the starter?
These cars have a crank-till-start feature, you actually don't have to hold the key in the "start" position for the car to crank.
From experience with other cars, clicking might mean the battery voltage is too low to drive the starter. So I'd check that. (Either use the voltmeter or google w203 dyno mode)

Either low voltage or a cooked starter/solenoid is likely. If you can hear it clicking then the starter relay is operational.
Have your battery properly load tested.

Starter relay is in Cavity S of the front SAM.
If no joy try jumping direct from +ve battery terminal to starter solenoid.
