Cud it be the bonnet sensor?? Where is it? Is it on the bonnet or in behind the latch?

Mine is on a little bracket by the scuttle panel on the right hand side.

you are looking for a little plunger somewhere where the bonnet meets the rest of the car when its down, also check the boot light is turning off (phone on video in the boot)

Can also be a sign of a failing car battery

Is it a little sticker thing goes up and down? What do I do to adjust it? I seen previous posts about weather temp affect it so the car sense the bonnet is open?

I am pretty sure it's the bonnet. Opened it yesterday and played around everything that moves. It went ok for a day and the alarm went off again last night at 3 am. My neighbour must appreciate this so much now. Lol

if it is the bonnet sensor, you should see 1 wire coming off it, disconnecting and insulating that wire should bypass it

Oh? Can I just disconnect it? Great... Thx.
Just to make sure that it's the one on the right hand side, close to the firewall, 10 cm left to the strut tower if u r facing the engine bay right?

no idea, its aftermarket, so not a standard place, if you want to get an answer, you are going to have to post a pic

Best thing to do now is go round and apologise to your neighbour(s) and tell them your're fixing it ;).

My Clifford 650? used to go off all the time from the cabin shock/ proximity sensor. Was a real pita.

I meant they are fitted after the car reaches the uk (if standard alarm) I think, so sensor could be in different places

You should count the flash sequence from the red LED as it'll point out which sensor triggered the alarm- might not be the bonnet! :)

i think the problem is my driver side door lock... coz i can see the lock open signal on the dash when i closed the door. then i opened it and shut it hard and the light goes away.. im so annoyed now... easy fix?

interior light? do you just have that off, or does it come on when you open the door, and off when you close the door. The actual plunger for that door are easy to replace, cheap enough, but also they are possible to strip down and clean up the contacts

its the actual plunger itself. If i push it up and it doesnt come back down. Feels like something stuck inside or too much dirt.. lights goes on and off no problem.

If the light goes on and off correctly i wouldnt think its that but, im going off the setup on my 5, not sure if later cars maybe slightly different

the door lock thing I assumed worked off the same plunger, but I could well be wrong

now, the car was taken apart a month ago doing undersealing... a lot of dust and dirt gone into everywhere... did compare the passenger side, the driver side seems a bit less smooth for sure.
