the cl and s class v-12's are probably one of the worst engines benz came out with. the oil leaks from the oil cooler is common and misfires from faulty ingition modules are common. now as far as oil in the harness, you first need to find out what is causing the leak. once oil enters the wiring harness, current carries the oil through the harness untill it reaches an end point, usually other connecters or the me control unit. as that point, it is wise to replace the harness and the leaky component as oil causes extra resistance. the usually part that leaks oil are the shutoff valves on the driver bank.
understand that not all techs out there care to point out things wrong with the car. others if they notice something will try and sell it. its best that you find a dealer who will point out potential issues and whats wrong with a car. my advice to you is get rid of the cl600, or get a really good extended warranty because repiars are not cheap. especially the oil leak. once oil hits the ground, its expensive, around $5000 to start. the parts that leak are cheap but the labor to replace them arent.
