A4 Doesn't Honk and beeps when car doesn't arm
 

My car sometimes beeps intermittently when arming the system. It eventually goes off after 30 seconds.

When I arm the car with the remote, the lights flash, but no audible except for a slight beep, very faint. Unless of course the 30 second beeps starts again. The panic button triggers the beeps again.

I'm guessing something's off, and the previous owner disabled the horn audible???

Anyone know what the issue might be?

When arming, your confirmation is a quick beep; there is no horn honk. If you don't heard the beep it means it's not armed. This happens when a door is not properly closed, etc.

It sounds to me like everything is normal for you...

Thanks for the update. I do hear the beep indicator when the car arms. However, at times, the car will continually beep for 30 seconds after arming. The used dealer I bought it from said it's b/c the car didn't arm 'properly'.

When the Panic button is hit, the car doesn't honk, it beeps like the arming issue noted above. My experience is usually the horn sounds when the alarm goes off or if the panic button is hit. the beeping is just too faint a sound to really be a deterent.

The beep is the way the Audi works it should not be too loud bit it should not be too quiet either!

Re: A4 Doesn't Honk and beeps when car doesn't arm
 

Thanks, but should it beep instead of honking when the alarm or panic button is set off?

Also, is it normal to beep continuously after the car is armed/mis-armed?

Thanks,
George

Further to this, yes, I hear the one quick beep when arming, however, for some reason, some times, when the car is completely secure, a series of beeps goes off for an extended period of time, lasting about 30 sec.

yes, the panic button only sets off the beeps. There is no horn "alarm" or indicator on the car.

thank you all for the feedback. i'll sleep better knowing there isn't some electrical anomaly creeping through the wiring of my car.

i have the same problem with the beeping...drives me nuts when i lock and it starts going off. I read online that the battery might be dying and being that the electronics are so sensitive in these cars it is not getting a constant voltage thinking that someone cut the power on the car...

Re: A4 Doesn't Honk and beeps when car doesn't arm
 

i also was wondering about the alarm part of this issue. So Audi dosen't have a LOUD alarm even if someone is breaking into it? Or if you need the panic to notify people your in trouble. what's the point if it dosen't deter someone or let people in the area know.

Re: A4 Doesn't Honk and beeps when car doesn't arm
 

Precisely what I was concerned about...it seemed off that the horn wouldn't sound. Now that I know it's not a mis function I feel a little better.

Re: A4 Doesn't Honk and beeps when car doesn't arm
 

Not sure about my battery, will have to test it. Seems ok, though. I'm worried about having to replace the battery, as i don't have the radio code yet.

Yes, drives me a little nuts too. At least we're not alone.

Re: A4 Doesn't Honk and beeps when car doesn't arm
 

yeah I get a high pitch beep too. Im sure if someone came busting through the window the horn alarm would sound... atleast I hope it would. That small beep doesnt even scare cats away... WEAK!

Re: A4 Doesn't Honk and beeps when car doesn't arm
 

Nicely said, and you hit the nail on the head...lol

Re: A4 Doesn't Honk and beeps when car doesn't arm
 

heh, hey anyone know how to get the horn alarm to sound? i wanna make sure it hollers...

Re: A4 Doesn't Honk and beeps when car doesn't arm
 

from what i know from my other alarm sytems. if you rock it or give a firm hit on the back window. should set it off if it has a shock sensor. if not get in and arm it and try to get out with it armed. I;m going to try it when i get mine back form geting winthers put on.

good to know

Re: A4 Doesn't Honk and beeps when car doesn't arm
 

Go to a store that sells Boat alarm horns, or trucker horns :D I personally like the boat... you can basically retro fit an aftermarket horn with the one in the back which honestly really sucks. I know that with a vag-com you can connect your horn to go off as well in the programing but I havent looked at it. I remember there was a setting in there though

Re: A4 Doesn't Honk and beeps when car doesn't arm
 

I have the same problem. It began after a battery was changed in a key fob. The dealer reprogrammed the system and both keys. No improvement. Said the "siren" must be changed. They called the beeping thing in the back of the car a siren. It seems there are rechargeable batteries in the siren assembly that die and are not replaceable. Very expensive. Does anyone know if the siren can be disconnected without triggering the anti theft system?

Re: A4 Doesn't Honk and beeps when car doesn't arm
 

why couldnt they just use a normal alarm hooked up to the horn...sometimes these engineers are real idiots.

Re: A4 Doesn't Honk and beeps when car doesn't arm
 

The alarm system has a secondary battery and that tends to die sometimes and needs to be replaced. That is the issue!

Re: A4 Doesn't Honk and beeps when car doesn't arm
 

mine does honk(back of the car) when i arm it but sometimes the alarm goes off for know apparent reason like if someone hit the panic button, light flashes and all that, i unlock the doors it's stops lock then again and it's starts all over again. I check all the doors if they are closed right but it still does it, I have to unlock and lock it several times before it stops.

Re: A4 Doesn't Honk and beeps when car doesn't arm
 

Mine dies the same but no flashing lights. Sometimes nothing turns off the beeping except waiting 15 or 20 seconds. After the beeping runs its course the lock and unlock operate normally with a single beep cofirmation. After driving the car a bit the same cycle occurs. Does anyone know if the alarm horn can be disconnected without confusion the security system?

Re: A4 Doesn't Honk and beeps when car doesn't arm
 

I can say for a fact that the "back siren" is as loud as it gets!
My car was broken into in the wonderful city of Edmonton, this is how I know!

The reason for the faint sound is that nobody in their right mind will approach a break-in in progress and there is no point pissing-off the neighbours! THat is only a warning to the people who are damaging your vehicle.

In the AUDI case, when the car is "attacked" the doors are immobilised: they do not open/unlock and the car will not start unless a FOB is used. Also if the car is locked and armed with someone in it the doors do not unlock... the siren will sound faintly.

The vehicle also has a "tilt" alarm in case of being towed illegally or lifted while the wheels are being stolen... the siren sounds and the car immobilises: no ignition no doors can be open without a FOB.

Re: A4 Doesn't Honk and beeps when car doesn't arm
 

I did read every single thread…
All of a sudden when I lock my car with any of my key fobs, and making sure all doors, hood/trunk…etc are fully closed. Pressing the key fob, he lights light up the car close up.
The driver side red light stays one for a few seconds and then blinks which to me means that the alarm is armed/activated but no chrip/beep as before!
Same goes when pressing the panic button, hazrads lights go on non stop but no sounds whatsoever

I guess the battery inside the horn module should simply be cracked in order to replace the 3.6 volts battery?
This module is located on the right side of the trunk
Would this work or I need the dealership?
Or screw it! Who needs alarm and beep as long as it locks completely???

One post said it was a costly $250 part (voice coil shorted internally)
Any suggestions please?

Re: A4 Doesn't Honk and beeps when car doesn't arm
 

doesn't it run from the car battery? if so it sounds like the horn module is gone.
