Where To Find Breakout Diagrams For OEM Blackoptics Grill and Underbelly Pan
 

Hello All,
I have poked around on Google with no success, so i am hoping someone might know how to do this because I have asked other questions about parts and how to attach them and people reply with break out diagrams.

I want to determine the OEM part number for the 21.5mm dowel pins that secure the front underbelly pan of a 2014 S4. Where can I find that information on the internet - preferably as part of a breakout diagram? An image of the dowel pin locations is in the post below this one. I also want to know the OEM part numbers for the S4 badge and Audi rings on the 2014 black optics radiator grill.

21.5mm Dowel pins for underbelly pan of 2014 S4.

If you are wondering why I am posting an image of an aftermarket underbelly pan, I purchased my S4 used and the front and transmission underbelly pans were missing. I ordered metal underbelly pans from ECS tuning for model years through 2012 by accident. The only difference in the kit I bought and the one for 2014 is that three 21.5mm dowel pins (and three wide speed nuts) are not included.

ECS Tuning sells the dowel pins and nuts individually, but when I search other internet sites using the manufacturing part numbers, the sites state the dowel pins and nuts do not fit the 2014 S4. I am confused and want to determine the correct OEM parts and then purchase those parts.
