Good morning. It's been ongoing but when the car sits more than 2 days OR It's below freezing(22 this AM) the idle is VERY rough like a misfire(only once did it throw a misfire code), smooths to normal after a few minutes and doesn't do it when it's warm out or being driven everyday. Oil is fresh every 4-5k, plugs about 5k ago and new serpentine belt at the same time. Could this STILL all be a battery issue? 2017 2.0T Q4, 49k miles, and as far as I know original battery. It has never not started just the rough idle as described along with start/stop light on dash then that goes out after a restart later in the day.
