C230 CEL Code P0304
Had a problem with my wife's car CEL, engine runs rough, sounds like a volkswagen beetle - P0304 Cylinder #4 misfire. I searched the forum and could not find a direct match for my engine (non-kompressor).
I fixed the problem by replacing the sparkplugs and both ignition coils. Just posting this for someone else's reference.
