Hey all

2000 A4 1.8T my car alarm always going off for no particular reason, sometimes I'll standing next to the car & the alarm went off beeping & the lights start flashing & then just stop. Ex the wind blew by the car & it went off, other car pass by & the alarm went off or just randomly the car just start to beep, but now I,m getting tired of it & I don't know what to do to make it stop. My friend told me about the car sensor to turn it off but I don't where it's at or anything about the sensor. so if anyone had to deal with that kind of situation please help cause it's annoying & kind of killing the battery also, so please help.

 

I have a 1997 Audi A4, with the same problem! It goes off mostly if I leave the windows cracked and lock it. I do that because It's too hot to leave them rolled all the way up, and all day long that thing is beaping.

 

Also, (As Im sure you've done) there should be something in the manual explaining how to turn the sensor off. I did to mine once or twice for those reasons.

 

There are pressure sensors at the top of the door frame so if you leave the windows cracked and wind blows in there it will set the alarm off. There's a button down next to the driver's side seat on the b-pillar(?) that you can push to turn them off. You have to do it every time you lock the car though.

 

You can also recrease the sensitivity of the alarm using a Vag-Com.

 

Thanks yall

How do I recrease the sensitivity of the alarm using a Vag-Com. Please explain with details please. For a minute there I thought I had to bring the car to the dealer to get the probl fix. So please any one

 

I just got a 2001 Audi A4 yesterday and I am having the same problems. I tried to lock it manually from inside of the car and all of the doors lock except the drivers side. I tried to lock it manually with my key from outside, looks like it automatically turns on the alarm because the red light on both drivers and passenger side doors pop up. I have tried to press the button by the door to turn off the sensor, I locked it by pressing the alarm button and the red light does not come up for a minute then a little later the red light comes up, does this mean that the sensor is off still? I don't understand I thought the red light would not come on. I tried to put my alarm on and then try to open with out pressing the alarm, it wouldn't go off which is really weird....please help tell me what the best thing to do to prevent from the alarm going off by itself.

 

start a new thread

 

Usually has to do with the motion sensors.. Think I read something about this, do you leave any windows open or your sunroof open when you leave the car? Because wind or a even something as small as a leaf could cause these issues... I think the motion sensor on and off button is located somewhere around the drivers side floor... Id know but I havent seen my car in over a week I HATE MY CLUTCH!

 

Wasn't there just a thread about this? Why resurrect a thread from last year? Haha.
