No, there is no such thing as original equipment mudflaps for an S3. If you ask an Audi parts dept they will tell you that the A3 ones do not fit. But from personal experience, buy two pairs of rear A3 ones. The rears fit easily with self tappers into the bumper. The fronts are a bit more difficult as mentioned you have to make or buy some clamps to hold the top of the mudflap onto the wing to avoid having to drill it.
