Took on my first real DIY upgrade on my new to me 2017 TTS. I knew that I wanted to do something like this after cleaning leaves out of my wife's 991.1 this past fall, but I'm not sure I would have attempted it without having this forum as a resource. So after spending a lot of time reading and watching how to remove the front clip, I took the plunge and ordered the Rennline grilles (decided against the Zunnsport based on fitment esp with my ACC, although it also looks like a quality product). Overall the install took me a few hours since I wanted to take my time and learn the car as I went along, and I had to improvise a bit with the actual install of the grilles as the photos in the instructions were an exact match for my vehicle (and they don't go into a ton of detail). Additionally, I had to remove and reinstall my sensors for my laser system (which probably added a good hour to the process so that I could properly prep the area for the install). That said, it's pretty easy overall. It just takes a bit of time to get everything taken apart and then back together. I'd estimate that I could probably do it in half the time now that I've gone through it once, but hopefully I won't need to..

Lastly, thank you again to all who post their questions and to those who help answer them, it what makes this forum so great. Here are a couple links that helped me tremendously:

Now on to some pictures, as we all know, it didn't happen if there aren't any pics (and apologies that I don't have more of the actual grille install, but I was getting pressure to finish up from the wife).

Getting the front up on jack stands to get better access to the screws holding in the fender liner. Helpful tip: I used a hex offset drive adapter ($20 at home depot) to remove most of these screws.





Side marker removed. To remove, pull the whole light housing backwards towards the rear of the car. It will move backwards a couple of millimeters, then you can rotate the front of the light away from the car. Once the front of the light is out, the whole assembly comes out easily.






Taking stock of the screws, so that I can keep track.






In process of removing all the plastic covers from the frunk. I removed the top, then the sides, and lastly the bottom. Easy enough, just need to be gentle and patient.






Bottom of the fender liner released.






Tubing for the headlight washers is located behind the driver's side fender liner. Push the whole tube towards the center of the car to release from it's bracket. Then remove the clip that holds the tubing to the connector. Once the clip is removed, the tubing pulls away easily.

Front Clip removed





Tubing for the Turbo/S front spoiler. Located on the passenger side right above where the fender liner and the front clip meet. Two tubes are simply disconnected by pulling apart. Reconnecting, is just the reverse.

Note: housing around the ACC unit. This housing will actually go around the grille once installed.






All done -- hard to see in this lighting, but happy that I won't have any more debris collecting in front of my radiators!






Center grille: Note that ACC housing that is attached to the vehicle goes around the installed grille. This takes a little manipulation to reinstall the first time, but with a little patience it is easy enough.






Driver's side grille installed. You need to remove the 4 screw for the lighting housing to install the top of the grille. You do NOT need to remove the entire light housing or the headlight washer nozzle (ask me how I know


Passenger's side grille installed.

It would probably be marginally easier with a lift but likely not by much. What was key for me was access to the screws for the liner (I contemplated just using my front lift function) and having clearance under the front to remove the screws at the bottom of the clip. I’ve seen it done without any of the above, but seemed easier to just lift up the car.

Good luck!

thanks. You’ll find the connectors inside the fender liners: 1 brown connector towards the top of the drivers side and 1 brown and 1 white connector towards the top of the passenger side.

sorry I didn’t snap additional photos of the grilles prior to install. Do you want to try posting pics of everything you have and we might be able to help you identify which is which?

Biggest pain for me on the install was the center grille. I could not get the housing to separate from the bumper in order to drill the holes for the screws and lock nuts that hold the grille on. Had to do it while the center housing was still attached but their is little room to fit in a screw driver on the outside to hold the screw while tightening the lock nut. No instructions on how the center comes apart. Took me as much time to do this as the entire R&R of the bumper and side screens together.
