Popping Noise when Passing Other Cars

Recently bought a B9 S4. Love it so far but noticed when on A & B roads, when passing other cars, there is a popping or dull knocking comes from the rear driver's side.

Would take it back to dealer, but I travelled from NE Scotland to Southampton to get the best spec/deal.

Any ideas?
