Button on A3 door pillar ???????????

[tigerminx1]

Hi to all, just purchased an A3 (2000 1.6 Sport) and i didnt get the handbook with it.
Ive found a button near the base of the drivers door pillar, and judging by the icon on it i presume it has something to do with the alarm sensors or something !
Could anyone help me out as to what this is, while i wait to get my hands on a manual ?
Mnay thanks in adavance.

P.s. Just transferred from the 'Dark side' of Renault to Audi, so boy am i enjoying life at the mo !!!!

If you press this before leaving the vehicle, it disables the ultrasonic sensors inside the car. Just incase you leave anyone in the car.

It resets when you open the car again

I was wandering what that was for. I think the button has come off mine but it has a red LED in it, is this the same button, mine is a 1999 A3 T ?

yep it is!
all cars have these. its basically if u leave a pet or someone in the car while still activating the door alarms and immobilliser
