Anyone have a similar video for the N63TU2. I have a 2018 m550i and I noticed that the main reservoir has required a top off every so often but the secondary is actually overfilled. The main reservoir coolant is blue but the secondary is filled with green... Should I have this bled and start fresh with the blue coolant? I did notice that my a/c is not as cold as it should be and my heat is hot only at 84 but if I turn it down to 80 it becomes very cold, no heat. Anyone else have similar issues?
