Mini One 57plate loosing coollant
Discussion
If it were losing water at that rate through the cap I'd expect it to be visible. I would be more inclined to think that it is only losing under pressure and possibly post thermostat. Get it up to temperature so the rad is hot and work your way around the circuit. If not visible then get a garage to pressure test it for you..
