Is my alarm siren faulty?

[softscoop]

Yes it's a direct fit.

It comes with wiring as it's sold to be installed in cars with no factory alarm siren.

You can swap the module over and bin the wiring

Thanks soft scoop, I'll get one ordered up.

just to add about alarms , mine would chirp when locking/unlocking but just flash the hazards lights when activated by locking with window open and waving about inside.

  So I took out the alarm from under the wing ,cut it open and checked the battery , at 7/8volts and no corrosion around it assumed it was ok. Sealed it up and refitted it and it worked as it should do.

 

  A week later it had stopped working again and a scan with vcds gave this :-

The other fault was a bulb out in DRL s

 

I find it strange that by disturbing it and swearing at it made it work for a while

 

Going to order a Chinese one and fit it to see what happens. (incidentally its supposed to be Bosche, Made in Hungary )

 

Any ideas anyone.

I would try a replacement unit. It is not just the horn sounding unit, it is the pcb electronics as well. Could be a failed component, dry solder joint.  Replacing would be the place I would start.

Fitted a replacement from china , ( made in Hungary ) and works now , although when first trying it out it wouldn't work .   Worked after second try but with a different accent , Chirp is a more musical sound ,( to me anyway )

[TheClient]

Battery in replacement unit probably had no charge initially.

That's probably why it didn't work first go ,  thanks

Thread revival!! I'm now having issues with my alarm constantly going off. Within maybe 30 seconds of arming. Scanning for codes using my bluetooth device two codes come up. 01134 and 01135. Alarm horn and interior sensors. Swapped over the sensors in the glasses holder for known good ones but still going off. I'm now thinking maybe the siren is faulty but it is making a sound when it goes off. Any ideas anyone? 2007 vrs tfsi. Is the siren under the front drivers side wing?
