When I set the timed climate to come on in the morning (7am) it fires off the alarm. Its happened twice when I've set it, and the alarm goes off about same time, (7.10am)
When I cancel the timed climate it doesn't fire off the alarm. I'm I doing anything wrong or could there be something I need to look at that might be causing the alarm to go off?

Are you confident the battery is fully charged and in tip top condition? I'm thinking a voltage drop as the heater starts up could be triggering the alarm. Previously..

Get away!!
The exact same thing happened on mine this morning!!

I'm putting it down to the battery showing its age, so getting it checked out this week.

could be a faulty bonnet switch which is going off with the increase in heat from the fbh.. ... - .- -.

That had crossed my mind but it was in at land rover this week and I asked them to check the battery with their wizardry machine. They said it was good and in need of a good charge. Which I did over the weekend and it was back in this week again to finish off a warranty job and I asked them to recheck it and it came back very good 75% and they didn't recommend a change. But I'm thinking sack it get a new un on. A hard frost will shorten its life.

In a post only last week I couldnt get the timed climate working so looks like it could be clapped out.

Ah, Stan where abouts is the bonnet switch? and can I use WD40 on it?

It's never going to get as hot under the bonnet as the engine running. If it were temperature related when you locked the car after a run then that would trigger the alarm... I would have thought.
The FBH will soon drain your battery if it is not perfect. Previously..

Ok, it's firing off after about 10 mins of the FBH working. I've read on here that the FBH really takes the juice out of the battery.

Genuine question - why would a FBH put strain on the battery if it's using diesel fuel and not battery power to generate the heat...?

Runs quite a few electrical systems as well, there are valves involved and the fans in the cabin run along with the water pump in the fbh and the diesel pump in the rear, also several ecu's fire up to monitor temps.

Pretty decent drain there

It doesn't require much of a drop in the battery voltage to cause all sorts of problems. There is nothing that can't be fixed with a hammer😜😜

Makes sense now you've listed what it uses.
Ta.

My car has had a long a complex problem with the FBH/park heating failures but that aside, one of the things LR advised me during one of the many fixes they applied, was that alarms triggering while the park heating is running is a known problem and there is a fix for it. Apparently the trigger is the warm air being pumped into the cabin by the FBH is fooling the alarm ultrasonics. The fix is a software upgrade to the relevant HeVAC / alarm systems.
