Does anyone know if the 2020+ M550's share the same Big Coolant tank as the M5? I'm guessing yes. My car has been in twice now with "low coolant" and coolant smell inside garage. They keep telling me its "normal" which I know is bullshit. The next time I get a low coolant warning I'm going to insist they swap the tank. My 2020 M550 has 13,300 miles.

They "Pressure Test the System" and say that rules out any cracks. Which I still say is bullshit. I can SMELL the coolant so its leaking out somewhere.
