Just decided to test mine, and the little indicator lite on the button doesn't go on when deactivated and the door security lite doesn't stay on for a few seconds like it's supposed to when you deactivate the motion sensor. Anyone else have this problem? Do you think this means that the motion sensor itself is malfunctioning--not providing protection--or that only the turnoff switch is malfunctioning?

I use mine all the time and you must activate it with the driver's door open. If it doesn't work after this, then you might indeed have a problem.

The coupes and all other Audi's have an air pressure sensor. It is really designed to detect window breakage rather than detect motion. It will detect motion in some cases. The Roadster has a radar sensor that is designed to detect motion when the roadster top is down.

Interesting, how does an air pressure sensor work? (curious because I have a giant hole in the trunk

I don't think this is correct. Motion detector works even with the window open all the way.

Microwaves if I remember right. I may not be right, I remember the right things for the wrong q's

Not true: coupŽs do have a motion sensor. Ask my daughter!!

DuTTchman

Thanks! That works. Now why isn't that in the manual?

this prevents those 3:00 a.m. unwanted alarm engagements Glad I could be of help.
