The ABS system checks the rotation speed of the individual wheels.
If one wheel is a lot slower than the rest, then it is probably skidding, and the brake on that wheel is released a little.

The Tyre Pressure Monitoring System is a piece of software, that takes the same ABS systems information and says:
If one wheel is a little slower than the rest, then it is probably flat, and turns on the warning light.
It just needs to be reset, to know what "normal" is, when You change tyres.

Therefore, the Tyre Pressure Monitoring System does not need any additional hardware. Just the reset button.

No skidding. Does not spin slower.

The systems initially takes its calibration from pressing the Tyre Pressure Indication switch on the assumption that the tyres have been first checked for correct pressure.

If the tyre that is going flat, it has an effective smaller diameter and therefore smaller effective rolling circumference of the tyre. This results in the wheel speeding up and the wheel's ABS sensor register's this.
The algorithm in the ABS calculates over a short period of time each wheels characteristic following calibration. So recognises a tyre deflating by the rotational increase in speed. At a specific tolerance, the system warns. The warning can also occur due to abnormal loading of the Scirocco on one side or anything that changes a tyre's effective diameter.

No braking or releasing of brakes is involved.

Well, tried 27 as the Golf instructions said - no dice
Found the elecronic diagram that someone posted earlier in this thread, it says pin 35. That did the trick
It was bloody hell to get the wire out from the wrong hole though!

PS It has nothing to do with the ESP system. It is part of the ABS system (not being an authority on the subject).

"select the second to last bit/field." in the Roccopedia might be better expressed as "Select Byte 16 and set Bit 2."
