Battery Drain
Hi guys. Hopefully someone can advise with my problem. I've not been able to pick up a similar issue on the forum so here goes.
Car - 2008 Disco3 "S" 4.0 ltr V6 petrol.
On numerous occasions my battery loses power. At first I'd taken the car to have the battery checked by three different workshops (AA & the LR dealer when I lived near one) and all confirm the battery is fine - no issues. But the problem hasn't gone away & seems to be getting worse.
I've now taken it to an auto electrician in town (by the way I've since moved & the nearest Land Rover dealer is a 4 hour drive away) & they found that whilst the car is locked & parked there is a 6 amp draw on the battery.
The next time I had the battery run down, I took it back & they pulled the fuses one by one & found the stereo was drawing excessive power - even after 10 minutes after turning it off. They apparently googled the problem & found this to be a common fault with the Disco & the solution (they believe) is to replace the stereo?
This car is a Japanese import & when I tried the satnav with a New Zealand map at the Land Rover dealer in Auckland 4 years ago, they advised that the satnav & stereo were Japanese specific & could not be replaced with the New Zealand configuration so to change/repair the stereo is a now major issue. (The stereo is fitted with a band expander to work in NZ).
I have now had the stereo (& a/c in case this adds to the drain) off for the last two weeks & still have the battery drain down.
Terribly confused. Now have to park suitably to enable jump starting.

Do you have a cubby box fridge?- they draw a lot of current if left on whilst parked It can when others can't,
It will when others won't,
It goes where others don't.

Thanks for the link but I'm neither this technical nor have the suggested testing equipment.
Looks as if a trip to the LR dealer in Hamilton is the only way to fix the issue. They no doubt will need to keep the car for a day or two (or more) so this means a 4 hour drive in two cars there & 4 hours back. Then when it's fixed & ready, another 8 hour round trip. Not to mention the clearing out of my bank account to pay for all this.
can't you get hold of the gear to follow Robbie's guide ? it would save you a fortune and time AND you'd have learned a bit too !
I'm sure folks on here will "talk" you through any bits you don't think you can follow..

Sorry mate but I have an issue understanding half of what has been said. Gt lost on point 3 !
For the record I am over 70 & am not too confident in this stuff.
From what the local auto sparky told me about the fault being with the stereo, I have removed the fuses to the stereo - namely fuse #42, 43, 53 & 58 hoping one of them will just shut the stereo down but having done that, the stereo still is on just no sound. In addition, although the fuses do not indicate they control the central locking I am now unable to lock the car with the remote!
Rain has stopped me going further but in the morning I'll replace the fuses to get back to where I started.

Update - pulled fuse #58 & no more battery drain - YAY.
This fuse is for the telephone which is not an option on my car, infotainment display, multi media module & TV tuner - all of which I do not use. Only issue is it still seems to connect to the stereo as the display works but no sound comes through - including the CD's. The screen on the dash is now dead.
Having identified this at least should point the dealer in the right direction to resolving the fault & hopefully save me a couple hours labour in the process.
Now I just need to find the time for the 8 hour round trip to Hamilton. Will need to leave at 3.30 am to be there at 7.30 in case they need the car for more than a couple of hours. Hopefully this can all be done same day or I'll need to book into a motel.
Crikey … I travel for less time going on holidays !
Good luck with this.

I had an issue and mine was related to the ECU's not sleeping. The Radio also showed a drain, but it was the infotainment display not the radio (i think thats what you have identified) i removed the fuse links near the battery, i posted on here with the exact ones. Not sure this will help but it fixed mine and i have not had the issue since.2008 TDV6 HSE

Great. Thanks. I'll have a look for the posting & check. Been too busy with the house renovation to worry about the car. Have not used the car much lately but need to get this sorted before it's WOF in July.

great reading
i’ve not got a satnav as mines the base model, got to try and find a battery drain
have the T max dual battery system but when the main battery goes flat , i press the manual link and doesn’t make a blind bit of difference , aux leisure battery is fully charged
when the main battery if fully charged it works fine, relay clicks on and off
but still got a battery drain, will flatten the main one within 7 x days if left standing
main battery is an exide EA1000 , tested all the fuses in the engine bay with the bonnet switch linked out but to no avail
so think my next port of call is to pull the plastic covers off all the larger fuses and put a multimeter on them
wondering if there’s an ecu not switching off
am getting 0.40 m/amp drain instead of under 22m/amp , also wondering as mines the base model if there’s fuses that i may not need or maybe a more common feedback where others have had issues with a particular ecu drain error
