The major difference between the Euro & US bumper carrier (metal beam inside the rear plastic bumper cover) is an additional reinforcing metal plate on the US version. It will interfere with the Westfalia (BMW supplier for the factory hitch / tow bar) set-up.

This is why you have the Euro part number part in the US hitch set-up (new retrofit). Otherwise you take an angle grinder and cut the plate out and Weatherite or Rustoleum paint the parts.
