Parasitic load central locking
I’ve noticed I have a parasitic load, tbh it’s been there’s while and just have had the time or the weather to look into it Shocked

At rest I have 65-72mA
It was spiking from in the hundreds to 56mA disconnecting the UltraGauge from the OBD has fixed it.
After removing all the usual culprits eg relays with no luck, I then started on the fuses and found that the central locking is pulling at rest 40mA removing this fuse drops to 23 and as low as 7mA
I’ve disconnected all the actuators one by one but no difference. I think this fuse is also linked to the immobiliser because when removed the red led stops flashing.
So where would you suggest I look next? I’m a bit stumped Big Cry 2016 Range Rover Autobiography 4.4 TDV8

Have you tried disconnecting the internal volumetric sensor?
