Audi B6: Install Massage Seats from S5 B9

Hello everyone,

I am Morris and I come from Hamburg.
So far, I only know what a CAN bus is and what it's used for. But now I have a problem where I need some hardware.

Okay, so I bought the new S5 B9 seats, and they have pneumatic lumbar support adjustment that's controlled via the MMI, but the control knob for it is attached to the seat itself.

There's also the button to activate the massage function.
Nothing happens when I press the button unless the B9 Can system is active.

"So, I would need a circuit board that can transmit the analog signal from the massage button and the signals from the lumbar support adjustment to the seat control unit (ECU), and which would allow me to make adjustments."

You would need to tap into the signals from an S5 with massage seats and program them onto a circuit board so that they are sent when the buttons are pressed.

Is there anyone who would make something like that?

Thank you very much.
Best regards,
Morris.

Does anyone feel like tinkering a bit?

People who want seats like that could simply buy an A5 or S5...
