Based on the picture, it's missing the third port on the drivers side. The challenge with "RS6 Fitment", is apparently some of the early production cars didn't have the afterrun-pump routed back to the radiator, so those cars would not need the third port. The fitment guides don't seem to differentiate between the early and late designs, so they say they fit the RS6, but most likely don't.

It would be interesting to try and verify if the early cars really were different, anyone with a low VIN care to check?
