waffles

so the other day i stupidly didn't see a huge pothole and drove over it, and heard a hard scratching noise under my car.

as it turns out, there is a plastic/rubber covering over the metal frame where you basically put the car jack on; the long steel bar on each side under the car. that plastic thing is now half ripped off, so i'm trying to just buy a new one and install it. can't seem to figure out the name of it or part # though; any help would be appreciated.

this is for a 2013 S4, passenger side
