Range Rover battery problems

I've just bought a used (2004 model) Range Rover and heard beforehand about a simple fix to stop the battery draining every couple of days or so. I've had a "hedgehog" or "Porcupine" fitted in the heater circuit which has had no result and there are no error codes which plugged into a diagnostic system.

Land Rover say take it to a local dealer, but when I tried to book it in, they said they don't have the kit to test and fix it. Any advice?

I had heard that people attending events were doing their batteries in by running iceboxes off the accessory socket in the load area, so I wonder if the wiring for that might be suffering an overload.

The standard answer to this problem is to try switching off the interior light entirely. When these are fitted with 'see you out' dimmer switches, the switches can remain live, draining the battery, even though the interior light has gone off.

Two other JLR possibilities are a fault with the gearshift quadrant not registering that the car is in Park. And another is that, if you don't lock the car properly, the Bluetooth system will continually search for the phone it is paired with, eating up the reserves in the battery.
