Mixing other manufacturers coolant or a generic brand runs the risk of causing a reaction and causing precipitates to come out of solution and clog your cooling system. Considering that the turbos are cooled by coolant and that the N63 already has a reputation of a very fragile cooling system makes it even more so.

Thank you for the quick reply! I have no issue buying the BMW brand stuff- It is a hassle to order it though when I just bough the car and I'm already getting engine lights 😒. I want to drive this thing and not wait for this stuff to ship LOL! A local Autozone has this Pentafrost Part Number: 8114117 Coolant that says it's manufactured to the same spec as OE. I am tempted to put a bit of this into the car until my order of a few gallons of the BMW stuff arrives... Is that a horrible idea?? Based on your previous reply, it seems that I should just be patient for the genuine stuff to get here 
My vehicle is still under warranty, and I'm taking it into the dealer in a about 10 days to have two open recalls fixed (apparently the previous owner ignored them?). I would think a coolant leak should be fixed under warranty, am I correct? |
Have you looked to see how low the coolant really is? If it's just below the min line you should be ok. You can put just a tiny bit of distilled water to take it over the min line to get rid of the warning. That little amount shouldn't cause problems. Coolant leaks should be covered.
