Got the warning of low coolant which went away but I wanted to fill it up.

Thanks
Factory fluid; I see no point in mixing another brand or formula since the majority of it is what the factory installed. Depending on your climate, distilled water may be all you need.
Agreed use BMW coolant only or distilled water to top off. Ideally a mix of 50/50. I had the same issue low coolant in the main reservoir at 7500 miles but the aux was fine.
