Alpina B7 no start

Anyone know about why the car won't start if coolant is low? I replaced the thermostat on the B7, filled it with 50/50 mix until max level at the coolant expansion tank. The expansion tank for the intercoolers is still empty. I'm wondering if there's a sensor that is triggered to not let the car start of coolant is dangerously low or if intercooler expansion tank is empty.

You probably leaked coolant earlier or are leaking coolant due to a blown line. If there are no leaks then the water evaporated and air pockets formed. The pockets are being shuttled out and low coolant is happening. I suggest using less water and more coolant ratio.
