Hi. New A4 owner. 2004 A4 B6 3.0
I'm a bit embarrassed to ask this question because it may be something stupid that I am doing wrong. A manual did not come with the car. I've searched online and haven't found anything that seems to be my particular problem.

When I stop the car at night, the interior lights and fog lights come on after I turn off the engine. When I open the door, the car honks. The fog lights stay on for a while. Sometimes, but rarely, the car will honk again a little while later after I get inside my house. This will go on for about a week or two, then the car will stop honking and behave as I expect until the annoying honking starts again. About a week after I got the car, it was honking whenever I opened the door whether night or day. Now it is night only after I have turned on the headlights.

Please help. My neighbors are going to kill me as I generally arrive home around 3:30 in the morning and have to be sick of waking up to my honking Audi.

Question answered on another forum. Car has coming home feature. I disabled this feature and horn no longer sounds. Evidently it needs to be hooked to VOC to tell it to not honk the horn when coming home.

...odd. ive never heard of this,any idea what else it does?

just lets u know where u car is when u unlock it. apparently all the euro models have this and ive heard. Not sure how much truth there is to that though.

This isn't the little honk, but a looooooooooooooooong honk that would drive a person crazy. It was very embarrassing.

Thanks for all the help.
