No cold start when cold?
Anyone have this issue?
This past year I moved to a very cold climate. I noticed my car would cold start often as it should. But if it’s very cold like 30 degrees or under, the car will not cold start and just start up normally. Yes even after a long 12 hour shift at work.
Car is on the stock software, no tuning.
Anyone experience this?

It cold starts normally if its over like 30 degrees or so. But if its very cold like 18 degrees or 20 degrees, the car would not cold start at all. Even after not driving it for 12+ hours sitting in this cold weather. Very weird. Will see if dealer has ECU update.
I'm guessing higher idle that slowly drops down to normal, vs the initial high start rev and immediately dropping to normal idle.
I recently read very interesting article:

I try to follow this religiously, but when the windows are frozen you can’t immediately take off.....until now? I’m off to read that link real quick!
Interesting! I’m not sure about the kitty litter in a sock, but I don’t have an issue with ice inside the car. I would think rice would do the same thing as it is a desiccant.
But the water/alcohol mix to spray on the ice to melt it sounds just about right for me! For those that don’t read it, put one part water and two parts rubbing alcohol in a spray bottle, and use it to melt the ice on your windshield!
Good info for all of us about warming up the car! Thumbs up!

I’m not sure how many people actually read them these days, and also a lot of used cars are missing the owners manual, but in mine it specifically states the fact about not letting it warm up the way we used to with older cars. It basically states that as soon as the idle drops you are ready to go, as the engine warms up faster and safer under varying light load, than simply sitting with no load. You are just supposed to drive it reasonably and stay out boost as much as possible until it reaches operating temps.

I guess to clarify, I do not immediately put in gear and start going, I do wait for about half a minute to a minute or so, until the high idle from the cold start drops to normal, then I go reasonably until it’s fully warmed up. The government angle is one I had not considered. But I am seeing this more and more in cars, especially ones with direct injection.
