Thread: D3 alarm going off for no (good) reason

X4. I bent a paper clip into both holes of the bonnet switch connector and have had no problems since.

OK - definitely the bonnet switch - I have looked high and low for the actual switch so I can kill it off but can't find the @#@$% thing....
I've looked in the latches, around all the edges and same on the bonnet itself and no go.

Sorry to ask, but could someone tell me where it is so I can put a stop to it and keep the vehicle locked?

Thanks in advance for help with this!

Cheers, V2

Its in one of the bonnet latches, can't remember which one but if you look closely you will see a flat actuator that gets pressed down when the bonnet closes.
Part number is LR041431

Thanks Tote,

I was looking for it at night with a torch so must have overlooked it. Will check again today and pin it with a paperclip as others have done.

Cheers!

Pop your grill off, 4 tabs at the top and two on the sides underneath the bar.
This is the micro switch underneath the lock on the drivers side on a D3.


You can see the offending part of the switch where my finger is pointing to the shiny part of the switch.



You can either replace the switch or do what I did and muck around bending it until it works correctly.
Or do the paper clip/ wire trick.

Rich, thanks for your time taken to photo the latch and switch - love this site! So helpful indeed.

My problem turned out to be the cable connector just inside the bonnet behind the latch - easy to reach without removing anything.

The connector was loose as I could tell it wasn't clipped into the latch. I pulled the connector off, sprayed some electra clean into the socket and the pins, then pushed it off and on a number of times to "shine up" the connection.
Finally latched it into position and voila' ---no more intermittent alarm (so far so good).

Thanks again all for your kind assistance.

IO just wanted to add to this thread as alarms problems are so annoying.

I had the same problem on my Freelander and tried everything. Alarm resets, vacuuming air vents to catch any huntsman spiders. Etc.

At the next service the mechanics confirmed the bonnet switch and it us a common fault. They did a bypass while they ordered a new switch which they will replace at the next service.

It seems that the bonnet latch or wires are a most common alarm fault.
