Recently replaced the HEPA filter on my 2017 75D, took a look at the brake fluid reservoir and coolant reservoir while I was in there.
Coolant appears to be below the "MIN" line, but I checked in service mode and there is no warning for low coolant.
Is it normal for this level to be low through evaporative loss over nearly a decade? I realize this is a sealed system and not normally topped up.
I would estimate probably 1 to 2 litres low. No signs of leaks on underbody panels or floor, although I know the 3 way and 4 way valves are a common failure point.
