Wiring diagram for ESP button?

[komseh]

Does anyone know where I can find this? I have scoured the Internet and the Bentley manual and have come up with nothing. I've found diagrams for 2 pin ESP buttons on other VAG cars, but ours has 4 pins connected at pins 1,3,4,6 on the button.

I've forgotten which pins are which, but the wire colors are:
green/black | | brown/white/black
brown | | blue/grey

Obviously brown is ground
Green/black is +12v output

What are the other two?

Here we go:


It's in the Bentley manual but the term anti-slip switch threw me off.
