Completely ridiculous question. I bought a used 2018 Audi A5, very low mileage. I can't figure out how to close the trunk and have it latch. If I start the car, I can press the trunk lid down and it will latch, but that is it. If I unlock it with the convenience key, without starting or even entering the car, the trunk won't latch. The manual says something about a button on the trunk lid, but I don't see one there.
