Our 2016 Ecoboost threw a code a few weeks ago when it was very cold. It went away on my next fill up but it was the right catalytic converter. I also noticed about that time it seemed like I was seeing more white emissions from the exhaust than previously. The car was running fine though. As the weather has warmed up I still notice a little white smoke before the car warms up totally. But yesterday I was on the highway and put my foot into it to pass and there was quite a bit of smoke from the exhaust.
I check oil levels religiously and it's fine. The coolant seems to be staying normal too. My first thought was possibly a turbo coolant leak but I'm not sure? Any place for me to start looking, or if it's normal that's fine too.
