Why do you want video in motion. It’s illegal and not activated for a reason.
As far as I know you are correct. I think the RS6 comes with the system that monitors individual pressures but as you say that requires extra hardwareI was under the impression for TPMS you needed the proper sensors in each wheel and receiver somewhere for it to display.
The alternative monitors the wheel speed via the ABS sensors and pings an alert if there is a variance against the other wheels / tyres to check.
