Question about 2001 Audi A4

1 Answer

Alarm going crazy, horn not working!! Help!!

It seems like you might know a thing or to about these cars...I have a 2001 Audi A4. First the alarm would just go off for no reason either a few seconds after I would lock the car or after 10-15 minutes when the car auto locks. Now it still is doing this but now the horn doesn't work and when I push the lock button on my key the lights do not flash and the car doesn't beep.... Do you have any clue??? I could not find anything in the manual for the alarm system.

    I said that wrong...I apologize!! The horn works, it just doesn't beep when I lock the car, like it normally does.

Sounds to me like you have a problem with the central locking control unit is faulty,go into the boot below the rhs tailight under the right side inner lining,it is possible the unit is full of water and will have to be replaced,andy

You may have a sort circuit in your alarm system. Most alarm system only went off about 5 min. then will back to on again. If you plan take to the shop you might consider to buy a new alarm system will save you $$$

My alarm keeps going off on audi a4 the dashboard is showing that the boot lid is open but it mis closed how do i stop the alarm going off?


Have the lock checked on the boot. It might have got out of alignment and is not making a good circuit back to the alarm. Might be a loose wire.

Alarm for audi A4


Try disarming the car from the trunk. Sounds like the door lock switch is not deactivating the alarm, which it should, with or without the remote.

Find where your fuel pump relay is and check for power there. Most alarm tech's and alarm system dis engages the fuel pump at there relay's.

Simple things to check is the fuse first then go for the relay and if everything there is working properly, it could be your alarm may have gone bad or your fuel pump it self.

Good luck and hope this helps
