TPMS switch..
The MK7 was designed for 6 functioning buttons, just that the bean counters decided to renegade the TPMS & ASR/ESC function buttons to the touch screen to save costs. Some countries spec the higher end cars (GTI/R) with the ASR/ESC button & only China spec the TPMS button. So no Europe made TPMS button, so ebay & China for the module.
All ABS units have two slave outputs for Aux switches for safety, ASR/ESC & TPMS function, I have wired both switches into my car, fiddly to install yes, but way quicker than the slow infotainment screen.
Also if the infotainment screen goes down how do you reset the ABS unit for the TPMS function if you have altered the tyre pressures? Flipping VW!
