Hi my girlfriend just bought a 98 Audi a6 and for some reason the alarm keeps going off in the middle of the night. Can someone enlighten me on how to fix this?

 

Can you tell us if the alarm is the factory installed one or an aftermarket unit?

 

I have yet to look over the car, she might be bringing it over today so I can check it out.

Lets go with stock for the time being.

 

Ok. If its an aftermarket unit, sometimes they can be easily tripped if it has a shock sensor that is set to sensitive. You might also check the battery in the car. I have a Camry with an aftermarket alarm system that for a while would sound for some unknown reason. I found out later after having a dead battery and replacing it, that the alarm never did that again. So it may possibly be a battery with low voltage causing the problem.

 

What if its stock?

 

It might be the internal motion sensor - Can be turned off with the switch on the post just to the feft rear of the driver.

 

if its stock (beep sounds like a sick horn) even a light breeze with any window open (incl. the sun roof tipped) can set it off. On the drivers side "B" post at the bottom above the trunk pop is an overide. Push it and then close the door and arm it. the lights at the top of the door will blink faster to let you know it worked. That will disarm the "reach in" sensor.

 

Is there anyway I can just turn it off indefinitely? I don't want to deal with it right now, too many other things to do.

 

I have a similar problem. I have owned the car for some time, but today the stock alarm has been going off for no reason at all (or at least that I can tell).

I have tried the button on the side of the drivers door to turn off the interior sensor(no luck), but after about 30 seconds, it goes off. I pulled the fuse out to stop the alarm but instead of the horn and the lights going off, the turn signal lights just started flashing.

It starts up

Anyone seen this before?

 

i had same problem with mine A6 1999. It was motion sensor,
