Alright guys so for the past month or so I occasionally get a very faint sweetish/hot plastic smell after I turn off the car. It is can't smell it when I drive. The first time it was noticed was when I was driving very hard on a canyon run and the guys I was with could smell it. Took it to the dealer, they checked things out and said all was good. The smell has been faint and I don't see any leaks. Never found coolant on the ground and as far as I can tell my coolant levels have stayed half way between min and max. I have some faint white "water spots" around my engine bay. Mostly near my intake box and then along the radiator. That makes me feel like I could be leaking coolant. I've read on the focus ST forums that the smell is common with them, but I feel like it shouldn't be normal. Any help would be appreciated.
