simple question... where is the main loud horn on a 99 a6Q, not the security horn, the main horn that is used from the steering wheel. can someone show pictures and exact location. thanks

 

I think the horns are located at both sides of the front bumper, they are attached to the same assembly as the fog lights if I remember correctly, jack your car up and look under the bumper cover and you should see the power cable for the fog light and another cable, follow the order cable and you will get to the horns. This is how it is in my A6 I don't know if some other ones are different.
