Oh man. I went through this with ShopDAP in back in JUNE!
I even sent them multiple e-mails about their site not being clear enough for 2017 SE and Autobahn models without the full DAP package or just rain sensing wipers. For 2017 VW changed the mounting geometry or something which is why 17 SE and Autobahns need the "F" revision if they have rain sensors. There is some confusion about DAP and no DAP because pre-2018s can have DAP but not have the optional DAP stuff like the lane keeping and auto high beams, which relies on the camera mounted by the rearview mirror. 2017 Cars with rain sensing and/or DAP WITHOUT the lane keeping and auto high beams should get the F.
For the "C" revision to work, I had to cut the car's black cover piece with a dremel to make it fit. You can see on the bottom of the right side piece in the image below. I had to cut the upside down U shape to make it fit.
I also tried to buy a '16 trim piece but it WON'T work on the 17.
I asked if they could update their website to be more clear, and if they could swap me with an F revision. Guess what? No response. It soured me on them because they were initially responsive about it, but once I showed them the issue, with pictures and everything they just stopped responding completely.
Since I have a mild case of OCD, I ended up getting an F later and selling the C privately, since ShopDAP wouldn't take it back. The F fit perfectly.
