My horn just stopped working today. Maybe it's the cold?

Went to the dealer today. Fuse was blown and kept blowing. Both horns replaced, allegedly there was snow/salt in them, which is strange because this car has never been driven on snow.

Mine died last night. I don’t drive it in snow/salt, but it was 15F here. Will have the dealer take a look. Hopefully this isn’t an issue for more M2’s.

Had this issue as well; it seemed to sort itself out before I took it to the dealer. Based on what I'm seeing here however, it seems to be more cold temp than snow related (although I do drive in the salt/snow).

I drove from 5F Boston to the -10F New Hampshire mountain areas.

Also had my iDrive reboot on me all of a sudden.

It warmed up here and my horn is back. Apparently our performance M2 horns do not like cold weather.
