Alarm keep going off and after a service now indicator lights flashing when car switched off. Alarm still keeps going off. Have taken off bonnet switch, clipped off the wiring still happening

Is it a small light somewhere on the dashboard? I'm not familiar with that car, but any vehicle I've had with an alarm has a blinking light to warn you/intruders that there is an alarm on the vehicle. Check your owner's manual for more info.

Sounds like the bonnet switch might be going out. You have an electrical contact switch that tells the alarm computer if the bonnet is open or closed. Either a miss adjusted or worn switch will send a false signal to the computer making it think it is open when it is not, you will also want to check the wiring that goes to the switch for signs of chaffing or kinks as the wire itself could get and send a false signal.

your alarm system needs to be reset, it is indicating that the alarm had been set off by flashing fast...

CAR ALARM ISSUES

It can be any of the car doors not got properly locked or the door is locked but the switch is not sensing the door locked. Open and close each door again properly.

Or else its problem with any of switch wiring getting in contact with alarm wiring causing it to happen.

And last thing alarm connections need to be inspected. It's getting short somewhere in between.

There are few help links with solutions, to troubleshoot these types of problems. I suggest going through these links.

These details will help.

Thanks.

Check the bonnet pin (small switch that is pushed in and out by the bonnet opening and closing) which tells the computer if the bonnet is open or close, maybe its faulty or broken and the computer thinks the open is always open even though its closed.

Check under the hood. Often, there is a small switch that needs to be closed when the hood is shut. This switch sometimes comes loose and when the hood is closed the button is never pushed. Find the magic button and reattach it to it's mount so that the hood will press it when the hood is closed and that should solve the problem. This button works with the alarm system.

dear friend-when you use the remote it activates the alarm,and when u use the key it only activate the central locking,please open the bonnet and look for the bonnet switch,if you find the switch look where the bonnet and switch come together there should should be a rubber grommet that will push the switch when closing the bonnet.if it is not there the alarm will not work,do the same with the back door.

Hi,

I just wondered if you have had this repaired yet and what was causing it as my Audi A3 2005 model has exactly the same problem!!

In response to bs77bird - the two things are definatley related. When i am stationary and the bonnet light is on neither my front wipers or my windscreen wash work. when im moving, my wipers do work, but my windscreen wash still doesnt. When the light turns itself off occasionally, both the wipers and windscreen wash work when im stationary and moving.

Any help would be great as i dont want to get ripped off for something i could potentially fix myself!

I had the same problem with my 2003 x5..I took it to main dealer as it was going on for wks and wks and after putting it on diagnostic machine it turned out to be the tamper switch under the bonnet. It is a trip switch if anyone lifts the bonnet when alarm is set.....it is located top left hand corner. Hope this helps

I HAD THIS PROBLEM ON MINE,TRY CLOSING THE BONNET FIRMLY (SLAM IT SHUT) TO SET THE BONNET SENSOR SWITCH PROPERLY.
