At only 2000km (1200+ miles), assuming your are not towing full time, you shouldn't have used enough DEF to trigger a change in the reading. Remember, it will display ok until it drops below 1/2 full. Then the next notification is when you get to 500 miles left. I just added 2 1/2 gallons when the display dropped to 1/2 full. That was 4500+ miles with only 200 miles of towing.
