I've been searching for the plug to fill the hole (16mm I believe) when I remove my wiper assembly and am confused about what I need to order & where to get it.

One post I saw indicated that I needed 477 845 333
- when I called the local dealer, they said that the system says that it's just a screw.

Another post said I need the following:
011 11 814
477 845 331
477 845 333
477 955 439 - i think 2 of these.

Which is correct?

Does anyone have one or know where I can get one fairly quickly?

Thanks much.
