Mercedes plug wires last a long time and are generally not a routine maintenance item unless an owner yanks them off the plug improperly.
If you are having issues and just start throwing parts at the car without knowing what the fault codes are, then that can get very expensive very quickly. The OBD system is there for a reason.
