Why won’t the def fluid low light go away even after filling it up?

What is your question?

The def fluid system is saying the engine won’t start after 250 miles due to low fluid. I’ve cycled the car several times driven multiple times and it still saying this. It started at 500 miles now it’s down to 250 left.

How long has your 2015 Volkswagen Passat had this problem?
