Hello! I have a 2012 200 with the V6. It is a hard top convertible with 35k miles. The car runs and drives perfectly. Everything is functioning as it should. However, after returning home from a short drive, we heard a beep coming from under the hood. You had to be outside the car, standing next to it to hear it. It wold emit a beep every few seconds as it idled. I can't say if it does it when you are driving. You can't hear it from inside the car unless you are in an enclosed garage and listen carefully. Has anyone had this issue? Quick fix? Is this something purging inside the engine like a PCV or a purge valve? Any ideas will be appreciated.
