Why is the Door Ajar Warning Light on in my Audi Q4 e-tron?

Will the Door Ajar Warning Light reset itself on a Audi Q4 e-tron?
Sometimes the Door Ajar Warning Light on a Audi Q4 e-tron clears on its own once the condition that triggered it no longer exists — for example after several good drive cycles.
