I dont drive my m2 i this snow weather, but i still will let the car idle for 10 mins when it gets real cold like this if i haven't driven it in days.

Do you do the same thing?

id let it idle for a few and then go for a 10-15 min drive. never been a fan of just having a car idle for too long not exactly sure why but....

Once mine is parked I don’t do anything other than run the battery tender. I don’t see any value in a 10 minute idle. I can’t imagine anything gets hot enough to evaporate any condensation that occurs, especially if you are not driving.

What do you see as the advantage?

It was just really cold here

No need to do that. Just turn the engine on and see engine RPM goes to normal range after cold start and slowly drive away. Just make sure dont go crazy on throttle until engine is warm enough, and keep it under 3k. (Well if you go WOT you will kill yourself in this weather anyways)

Now weather is getting better and I need to wash mine

My ///M master tech said if i am gonna start it, i should let the oil get to normal temps before i shut it down,

(so it would be def longer than 10 mins)

I simply don’t start mine until it is out of storage. I can’t imagine any benefit if you aren’t driving it.

Driving is the proper way to warm up a car so rarely ever more than one minute and it's been -20 up here for a few weeks now. I just keep the revs down for the first 10 minutes of driving and it warms up pretty fast.

The point is for a car that going to sit in the garage for the majority of the time through winter, is it worth to just start it up when you have some deep freeze days

You probably won't make a meaningful difference in anything by doing so. I think you'd likely "contaminate" the fluids with condensation unless you ran the car long enough for everything to get hot enough to cause the condensation to evaporate. Whether that condensation is worth any benefit is likely not worth arguing about any benefit.

Letting it stay dormant isn't going to do anything, either.

Let it idle if it makes you happy. It certainly sounds lovely.

Didn't he also say that he has recently seen a couple of N55 seize up due to condensation/freezing issues? Seems the safest thing is to park it, slap a battery tender on it and cover it up until spring. Biggest concern there would be flat spots on the tires, but there are tire "ramps" available for that.
