I've had a couple of cars (not BMWs) that the colder it got the more electrical gremlins would hatch, especially if there was snow or it was snowing. One would get to the point it wouldn't start. If I let it idle for 30-45 minutes in the garage after I had driven far enough to get it up to operating temperature for 20-30 minutes it would be fine for a week. I would also put my shop light inside overnight sometime to get rid of condensation. It's those times where it only gets warm enough in the car to melt the snow dragged in but not enough to dry out the carpet.

BC...I hope the garage door was open and you weren't in the car :nanana:

Just kidding ;)

I have a heated garage and yeah I was thinking of parking it in there for a day or two. Problem is my garage is like a showroom with many 2 wheel toys inside. I do keep another classic car inside, not sure if I could bare to take her out over night :(

Temps dropped again, light back on....

Good to know.....not good it happened. The light might go off when temps get warm. My service engine soon light went of for about 5 days than turned off.

I have a friend at a body shop that can reset it but like others said it will probably come back on. I'll wait for warmer weather. This winter is kicking the crap out of all my cars. My 2014 GL has frozen windows that would not roll down, cars has about 400 miles on it.
