anyone know what the button on the inner b pillar is?

 

motion sensor on/off switch

 

+1, its interior motion sensors for when the alarm is set, like if you keep the windows down or something.

 

The manual for my '04 1.8TQ sport says that there are two switches, which there are in my car, one is the TILT SENSOR OVERRIDE switch, and the other is the TRUNK RELEASE switch. If the switch has a red led lit up when you press it, that would be the tilt sensor override, which you use when having your car towed in order to disable a sensor that activates the alarm if your car alarm is armed and any side gets lifted. Run-on sentence, anyone? (Note: flatbed towing is recommended by Audi for all Quattro models...)

 

thanks...............i was wondering way my alarm would go off at random, i thought the button was an on/off switch for my side air bags.....

 

Nice thread.. i always wondered what those buttons where..
