With the VW, you establish a proper condition by setting tires pressures properly, then you hit the rest button in the dash and drive it far enough to let it calibrate a baseline.
Personally, I like this system because it allows you to use non-spec tire pressures without throwing a TPMS warning.
As an experiment, I set the pressures on our Passat to 18psi (35psi is spec). I reset via the button in the dash, drove the car, and let the system calibrate itself. The TPMS light cleared even with 18psi in all four tires, which is exactly what I expected it to do.
So anyway, you have a TPMS system, just not sensors on the wheels.
