Thanks for the reply mate but mine doesn't fit directly to the washer. It's separate with a spring but can't work out how to actually fit it can't find no videos or threads on it. The mind boggles 

You're welcome, ah I see. Is it worth speaking to Audi parts department as they'll have a schematic.  

Yeah think I might have to take it in to see them. I've got the cover and the spring but it's as if there's something missing from the inside of the bumper for the spring to fasten too along with with the cover. I've looked and looked online and can't find nothing. Thanks for your help 

If one of the plastic prongs are missing off the bumper the. I believe the cute might be a new bumper. 

Hi did you figure this one out? New owner of a 2011 S4 B8 and both mine are broken but an online stripdown of the bumper shows a headlight washer guide frame, part no. 8K0807788H. It looks like this clips into the bumper from the front so it could be a very easy fix, I'm waiting for the warranty people to get back to me on this issue as they should sort it.

Hope the warranty company sort it. Make sure they don't bodge it!
