Indeed it does, you can get it from the BMW dealership. It's BMW orange coolant that is nitrate free (though it's not silicate free.) This is what you should
be using. It's not very expensive either.
High end GM coolant is silicate free, and phosphate free. (i.e. Prestone), however it is not nitrate free... which is the main thing with BMW coolant. If you can find a good nitrate free coolant from Canadian Tire, that is ALSO Silicate free... then you can buy this instead.
