FSD FIX ON MY 2017 MODEL S!!

I felt a sense of commitment and needed to post here for my fellow Model S legacy/facelift owners that struggle with FSD.

For context, I purchased a 2017 Model S that had the upgraded MCU 2.0 & HW3 FSD package installed. With FSD engaged, it struggled with these scenarios:

- Very hesitant driving well under the speed limit for no reason

- Lane change abort/failures roughly 75% of the time

- Touchy throttle while maintaining speed (always)

- Coming to a crawl or jerky speed in the intersection at a green light left turn.always struggled with various things like (roughly 75% failure rate)

I can confidently say and can confirm 100% without a doubt that installing the C revision side repeater cameras completely resolved my FSD issues on my 2017 Model S that had the A revision chrome repeater cameras. I had to deep dive into Facebook & Reddit forums and piece together information and noticed some key details people had success with which I combined that led to my success.

Here is what I did that completely resolved the issues I was having with my HW3 FSD on my 2017 Model S 75 RWD:

The part numbers for the C revision side repeater cameras I used are:

Left: 1495866-22-C

Right: 1495867-22-C.

The procedure I followed was:

- Replace old A revision chrome cameras with the new C revision parts

- Initiate "camera recalibration" in basic maintenance settings

- Go into the deep service menu (password: service), chassis, steering, reset steering offset)

- Let the car go into deep sleep (take the key and walk away for 30 mins)

- Then drive roughly 1 mile on city roads and then let the camera re-calibration finish on an 8 lane highway (4 lanes each side)

- DO NOT IMMEDIATELY ENGAGE FSD when the re-calibration finishes, go park and let the car go into deep sleep again (take the key and walk away for 30 mins)

- Then go for a drive and enable FSD and BOOM, completely resolved every issue.

I'm unsure if the deep sleep cycles in-between steps or the steering offset had any influence or not but that's just what I did and it worked and I don't want to reset my cameras ever again lol. The theory & logic is that the deep sleep cycles might allow the car time to clear old settings/calibration and then solidify the new calibration and settings. Again, just a theory, but it worked.

Doing that made my 2017 model S FSD drive just as good as my 2023 model 3 with FSD. I'm soooo so happy. I hope this post helps someone else with similar Model S FSD issues.

Some side quests I did while in search of finding the resolution:

- Get an alignment (good to have a clean baseline to build from) (no notable FSD improvement other than not pulling to one side anymore)

- Reset DAS and camera recalibrations individually in the deep service menu (no notable FSD improvement)

- Clean the front facing camera windshield glass (on the inside) (no notable FSD improvement)

- New set of tires (no notable FSD improvement)

All these side quests did not resolve the issue or improve the FSD behaviors at all but could have possibly contributed so I cannot rule that out. Ultimately changing the cameras and following the procedure was an immediate night and day difference.

Good luck my fellow Model S owners! There is hope for your FSD!! I hope this helps someone!
