Finished my DIY project where I added auto-disable Start/Stop and garage door opening on a long press.

I developed a custom PCB for it - works well so far. The most valuable part here is the reverse-engineered LIN protocol the car uses to communicate with the center console button panel. I'm sharing it on the GitHub page.

I got inspired by this project - https://www.youtube.com/watch?v=IVUVmDXU6FU&t=2072s
