Nope - exactly the same, at least for my 2004 it was.

I bought one of the VW/Audi parts and swapped out the old water inlet/outlet fitting from the MB part it was replacing and presto - I have the exact same thing that Bosh would like to sell me for $200+

That guy on eBay knows these parts are cut from the same cloth and that MB charges more because they are MB, so he's pulling a fast one on unsuspecting people who can make this swap themselves.
