Basically, is a piece of cake 10mins to finish everything!
Now this is the package I ordered from Audi for B8 A4 S-line.
Make sure you ordered the right parts!


1) First unscrew the only one screw under your fender.


Open it up and put your hand in it and try to touch the clips located
There are 6 clips in total*
2) Push the clips down in the other time try to pull it with the other hand


As you can see the top clips should be located, and the bottom one should be easy to find.


3) Now if you sure all the clips are pushed down the grill should be easy to take off


4) Make sure those should be the first thing to put in first if yours is S-line or S4


5) Pop the whole thing in and make sure all the clips are clipped.


6) Put the screw back and done!

Hope this will help from my experience guys
