Alarm goes off when charging at night!
I moved onto an EV tarrif which is cheaper to charge at night. However, I’ve found the car alarm goes off about 5mins after it starts charging at midnight! Has anyone else had this problem or have any idea why it would happen? Thanks

I also charge mine overnight using a cheap tariff but I’ve never had issues with the alarm.

Have you tried varying the way you lock your car, single press and double press? Not saying it will make a difference but but it might help in diagnosing the issue. Single press will not enable the internal movement sensors is my understanding. 2019 Range Rover SDV8 Autobiography

Thanks Buz1500 I’ll try this and see if it makes a difference or at least helps diagnose what’s causing the issue.

Update for anyone who this happens to as well (although it seems extremely rare) - the main dealership updated the BCCM (whatever that is!) and thought it would resolve it. It hasn't and they advised calling Optimised Land Rover Assistance.....the button doesn't work in the car (!) so called old style on my phone and they're sending out a Land Rover technician this morning - can't fault them on getting someone out quickly! Let's see if they have any idea why it's doing it!

another update (just for anyone that has the misfortune of this!) - the Land Rover optimised technician was great and arrived within a couple of hours. Identified that it's not the full alarm that goes off (i.e. no horn, no hazard lights, just the audible siren)....but that it does not log an alarm trigger so he couldn't fathom what's causing it. Back into the dealership next week.....!

The saga continues! The dealership couldn't recreate the issue in the workshop, which means they can't raise this with LR centrally! So I got it back with nothing fixed.....lo and behold, the alarm isn't going off at night on timed charging......but now it won't precondition and pings up with a message within a minute of starting preconditioning that the battery level is too low to continue....even though it's charged all night!

I had looked into this whole issue myself and got a second opinion, and thought it could be the 12v battery as this feeds the audible siren, which I informed the dealership of. They wouldn't do anything about it as they said the battery was fine. Now they think it could be the 12v as the message on preconditioning could be due to the 12v. Anyway, back to the dealership in the New Year for more fun and games!

I too have alarm going off (auditable, not full) when charging at night occasionally!

Hi JARowley, I thought I was the only one! Does this mostly occur when you use the timed charging function from the car or do you use timed charging set from your EV wall charger?

Mine is with the dealership again this week (third time) and they have finally raised a TA with LR centrally. They initially tried to tell me it was my wall charger and kept handing the car back! They also said they couldn't re-create the alarm trigger in the workshop and so couldn't raise a TA. I have to say they have been awful in actually listening to how the alarm triggers for me at home and attempting to re-create it in the workshop - lots of just plugging it in, not using the timed charing correctly.

However, after the last time, I also started getting a preconditioning error message (you've got to be quick to see it as it disappears almost immediately from the app - see pic). The dealership then said it could be 12v battery, which I had already mentioned to them but they said the 12v was fine when tested. I'm going to speak to them again today as they've had it over a week and should be getting more assistance from LR centrally via the TA - I'll let you know what they say.

I’m keeping an eye on this one. Mrs Fifer’s hybrid Evoque is in this week for the same thing - alarm going off when on a timed charge.

She’s got a new Disco Sport for the remainder of the week. Last time it was in we had a new RRS which was lovely.

Hi Fifer, that’s really interesting that Mrs Fifer’s Evoque is in the workshop. Have they said what they think the problem is and do they have a solution for it?

It was in before Christmas and they said they’d need it for three or four days to test. It was dropped off this morning,

They only confirmed they’d run the diagnostics and hook it up to their charger. I’ll update this post at the end of the week.

Hi Fifer, it'll be interesting to hear what they say for the Evoque - it seems to be an industry fault with hybrid and is related to the 12v battery being drained, although I'm not sure what the exact issue is. Whereabouts are you located, generally - in case my dealership (Basingstoke) just try to hand the car back again? I can at least explain that I'm not the only one with this problem.

Haven't had the issue with the BMW Hybrid and a good point on the 12v battery. Not sure how the BMW keeps this topped up as ours spends the vast majority of its times in EV. Can only assume it takes a charge from the Hybrid battery

The car is at Pentland, Edinburgh West. To be honest I fear a similar response.

I didn’t have this issue when I had my I8, although from experience with that and the Evoque I’d not run a PHEV without a top to tail warranty.

Just got the below update from the dealership, based on the technician advice via the TA:

Instructions: 1. Carry out the Helptext actions for BCCM P3039-68

- Refer to the electrical circuit diagrams and check the battery charger control module low voltage circuits for short circuit to ground, short circuit to power, open circuit, high resistance.
- Check the electrical connectors for evidence of water ingress. Check the terminals for damage and corrosion. Repair the wiring harness as necessary
- Check the cooling system for leaks. Rectify as necessary
- Drain the cooling system. Refill and bleed the cooling system
- Check the operation of the coolant pump. Rectify as necessary[/list]
