But draining your coolant and filling it is super easy. If you have ramps, 8mm socket, screw driver your good to go. Simple as draining old coolant, then refilling then doing the bleeding procedure. Theres a DIY tutorial in the DIY section of this form with step by step guide.

This is correct. What you are seeing is the Styrofoam float on the bottom of the level indicator stick; it’s just been discolored by the coolant. BMW coolant is blue. Fill the reservoir with BMW coolant mixed with 50% distilled water (50/50 mix) until the second ball on the end of the stick is level with the top of the filler neck. Simple.
Here's the DIY if you want to drain and fill the system.
