Hi Steve
First off get the vehicle in a state where you can work on it without disturbing 'sleep' mode. So bonnet, doors, tailgates and cubby box all open but latched to fool vehicle. I would then do 2 tests one lock the car with the remote and check drain after 16 - 20 mins and then do same again but just lock it with the key in the door. The difference should only be the volumemetrics. You are going to have to have this switched off to do your testing or you could cover them up - up to you. I prefer to do it the way I was shown! You may want someone to check to readings for you whilst you've got your head buried behind the glovebox or in the boot. I would remove each fuse in order and refit it and then note down which make a difference. Again this is how I was shown I find it easier to check each fuse in order then going back and forth etc. Let me know how you get on.
Best of luck,
Brian

Hi brian
Thanks dor all your help , im unsure how to leave doors tailgate latched,and fool the car to go into sleep mode ,how do i fool it? i know i can tape down the bonnet and cubby hole pin switches, also the second test with the key to lock the door will that not set the volumetric alarm,
Thanks
Steve

I just a slim screwdriver in the latches to put them in the latched position. Then you can just pulled the screwdriver back out to unlatch them just open the handle - sometimes you may have to apply abit of pressure on the claw mechanism if it's abit stiff. In theory locking the vehicle with the key disables the volumetrics eg: leaving the dog in the car. By doing both locking tests it allows you to elimate ( or identify )the volumetrics quickly.

I will let you know what i find

more info
started to pull fuses found when fuse 52- 25amp fuse is removed the amperage draw goes down from 150ma to 50ma, the fuse controls the front heated seats, but when fuse removed it stops the heated seat controls and the climate controls fan controls fan speed switches etc
anyone have any ideas?
thanks

could be the fsr [final stage resister]

the fsr has been changed 5 days ago new genuine land rover part 2007 supercharged ,Cairns Blue with Navy & Parchment Interior

Fuse 52 serves the HEVAC ecu which also controls the heated seats.
If you pull out fuse 12 as well as fuse 52 it will isolate the heated seats and leave only the ac / heating controls.
This should indicate where the current leak is ie seats or ac controls.
It's possible the new FSR is leaking current, I don't think they are particularly well made from new hence all the problems.

[mod edit-no need to use the quote when replying ]

so could the new fsr be faulty? 2007 supercharged ,Cairns Blue with Navy & Parchment Interior

It is possible

Not so much faulty but I don't think the manufacturing quality is particularly high.
I have a suspicion that if you checked a batch of new FSR's a good proportion would leak current to some degree. Some would be better than others.
I know when I changed mine due to current leakage the new unit still leaked current albeit to a far lesser degree than the unit it replaced which I accepted as being "good enough".
I still think they are a unit that could be significantly improved at manufacture.
Hence them routinely failing after a few years even though the design has been changed at least once.
They get very hot in use particularly in hot weather which I assume adds to the failure problem.
I would still carry out the Fuse 12 check to clarify things.

ok, thanks will check fuse 12 2007 supercharged ,Cairns Blue with Navy & Parchment Interior

Hi
Did amp draw again draw was 150 ma removed fuse 12 no difference, removed fuse 50 draw went down to 50ma so its somthing on fuse 52 taking out fuse 12 makes no difference, 2007 supercharged ,Cairns Blue with Navy & Parchment Interior

hi guys

I’ve had a battery drain for months every 2 days battery is flat

so I check yesterday and when the car went to sleep it was drawing 0.586 amps

so I started pulling fuse after fuse to i pulled the stereo fuse.

straight away it dropped to 0.060 i carried on pulling all the fuses but it never went any lower then that

it was the satnav unit not turning off so I’ve left that out now as its anyway

is 0.060 amps good enough or does it need to be lower

I’ve got the big 110amp bosh battery

hevac control module on fuse 52 and 34..have you pulled fuse 34 to see if it makes any difference.. ... - .- -.
