I’ve noticed on my e89 zed4 recently that albeit I do some Very short journeys that steam emits from the exhaust, basically since the cooler weather.
Anyone else have this situation?

Normal effect of burning a hydrocarbon and then passing out into cold air where it condenses

OR

You have a crack allowing coolant into the exhaust.

How does it smell ?

All cars 'steam' when the air is cold enough to condense the gases though of course (except when the exhaust pipe is so cold it condenses fully in the exhaust itself and drips out of the tailpipe), when fully warmed, the exhaust hot, the gasses disperse more before condensing and you dont see it
