I'm not sure at this point but I'm guessing :)

I could use these two keys that don't work right now...

You need Lin module

the buttons should work like this:

Left button - Main Menu

Right button- View

I'm considering soldering the Seat chip into the Skoda.

As I understand it, there are three types of button connections to microcontrollers:

- direct (1:1 each input pin has its own button)

- analog (several buttons can be connected to the same analog input, the detection of the activated button is in voltage, such as 3V....)

- network (this method is usually used with more than 8 buttons, this is how computer keyboards are also made)

When determining the connection for the steering wheel buttons on the printed circuit board of the keyboard type: 3V0 919 719E, I found that an analog connection of buttons is used, which are supposed to be two-channel. This assumes that microcontrollers could have more buttons programmed, the actual operation and use is hardware-dependent. If we wanted to confirm this, we would have to solder a potentiometer instead of a resistor behind the button, with which we could set any resistance, which would consequently change the input voltage. With the help of VCDS software, we could determine the function of the button....

In case of using a newer version of the steering wheel buttons: 5E3 919 719E, it would be necessary to check whether the circuit is made in the same way. I assume that this could change the operation of an individual button that does not work for us, we could probably change an unused button for new functions, such as using a phone call.
