Yes, this is standard. The conditions are basically: cold engine and outside air temp above 15 deg.One question i have, does anyone’s cold-start cycle occasionally seem really aggressive? Like it seems when the outside temp is in a certain range when i start the car it will run in a really aggressive mode for the first minute or so where it’s popping and banging until it gets a bit of heat in and then settles back to a normal idle?
If it's colder than that then it's as quite as a mouse.
