I'll bet Porsche will cover entire cost of repair in appreciation for you letting them know about their error message spelling mistake
No need to replace sensors... If you're going to be diligent about checking pads/rotors for wear, you can kill error message by shorting out the sensor (at plug is easiest and makes most sense):
Be sure to adequately seal up spliced ends to protect from elements (I solder together and then double heat shrink tube 'em.).
Good luck
