Hit an animal on the way home today and everything on the car is fine with the exception that on the bumper, this plastic cover thing popped off. It's about 2 inches by 2 inches and I dont know what it is. Anyone got any idea? The model is a 98 A4.

 

is this cover on both sides right under the headlights???
i think you're talking about the headlight washer...

 

Well its not directly under the headlight so I don't believe its the washer
