Went to the service today to book the car for tommorow (again, replacing the sump). When I returned to the car and turn it on, I've got a warning on the dashpod and 2 or 3 beeps. Checked the expansion tank, 2 inches below min. What the ***k is wrong with the car, I topped the expansion tank yesterday, there weren't any leaks below the car (except oil leak from cracked sump). 1-1.5l of coolant is missing.
