98 a6 alarm system keeps going off in middle of night, i have disconnected horn in boot for system but lights are still flashing. what is the easiesrt way to disconnect them from the alarm system

There is a fault with the anti theft alarm system or someone is trying to tamper with your vehicle and is triggering the security system.

It may be easier to just disconnect the battery at night. You could even buy a disconnect switch.
The siren is powered by a 10 or 15amp fuse number 12, but you would still have the hazard lights flashing. That is a different fuse. The actual keyless entry and alarm module gets power from several sources.

If a aftermarket alarm then disconnect it ,these auto remote start alarm things are useless and all go wrong with age

holdboth the lock and unlosk buttons on your remote simultaneously for about five seconds until the lights flash and horn chirps.that should do it.if not i believe these models used a separate horn for security system.possibly fuse for this horn is bad or the horn itself is bad.to see if this horn works lower drivers window.stand outside vehicle and lock doors with remote.wait about a minute and reach in window and MANUALLY unlock and open door(do not use power door lock button)this should cause the system to activate...horn should beep and headlamps should flash.if horn beeps try my first suggestion.if it doesnt beep and just the head lamps flash check fuses and horn for security system.

raise the hood and disconnect the battery. after the dealer disables the system make sure he notes it in the owners manual so the next owner is not on this board a year from now asking about how to turn it back on.

You need to reset your alarm system and the only way I know how to do that is to disconnect the battery and reconnect it.

You probably have a faulty door,boot or bonnet lock.If you put the inside light switch to the setting for the light to come on when the doors are open,close all the doors and see if the light goes off.If your model golf has a display on the dash,it shuold tell you which door is open.It could also be a faulty interior sensor or a faulty alarm horn.A diagnostic machine will be able to tell you which was the last alarm activation.

i took the car to a mechanic and had the alarm system disconnected and the horn reconnected

find the horn and look for a wire then cut the wire that goes to the alarm NOT THE HORN WIRE

Just voluntarily fire the alarm off yourself each nite before you go to bed. Just hit the horn alarm button and let it blow once and hit it again to stop it. If you do this each nite it won't go off in the middle of the nite.
