I assume to lose coolant would be a leak (nothing under car on driveway).
I also assume it was a duff fault warning, anyone had similar?

I had a similar problem recently. I have about 23K miles on my X3, and this was the first time that I had seen the message. On cold mornings, before the engine warmed up, I would get a low coolant warning. After it occurred for the second or third time I splashed 1-2 ounces of bottled water into the reservoir, which was sufficient to turn off the warning light. I had an oil change scheduled for later in the week, so I had the dealer top it off with BMW coolant during the service visit.
If I hadn't had the oil change already scheduled then I would have gone to the dealer on the way to/from work and had them top off the reservoir with approved coolant.
