Windscreen washer fluid capacity figures still seem to be a secret. There's no mention of this in the thick manual for my new 2019 B180d. Anyway, the "top up" warning message finally appeared and, in line with the results of my experiment with my old 2017 B220d, I mixed up 5 litres of fluid. However, I only got what looks like 4 litres into the reservoir before it appeared at the top of the filler neck. Therefore, and assuming that the warning message comes on as before at 1 litre, I suspect that my new car's reservoir is only 5 litres in total. So, when the warning message comes up again, I'll repeat my experiment again and post the results here.
