I didn't really hear anything abnormal in that video to be honest, though there was a lot of wind noise outside and what sounded like exhaust drone inside.
I can tell you this, from what I did hear your car sounded a lot like mine does in the cold. A high, loud idle, loud tapping noises, the works after I'm parked outside for awhile on a cold day/night. I think this is just how our cars are. I'll try to get a video of my car sometime, but it might not be for a few weeks or so since it doesn't look like its gonna be below 0c again for at least a week here, and the colder it is the worse the sounds are.
