Thank you folks for your inputs. I am still new to BMW world and any unusual events like this one always throw a warrning light in my head.
In a week or two a vehicle is gonna be at the dealership for some minor CPO warranty work so I just wanted to know (besides my previous post) if there is anything else for them to check prior for winter arrival. I have been reading on this form for infamous CCV/Oil Separator issues due to cold wather and this is gonna be my first winter with my X.

Cheers to you all
