Anyone measured the quiescent drain of the D3, alarm on with ultrasonics on ? I'm seeing 1.2A still, 15 minutes after locking it. Someone somewhere said that it can take 40 minutes to "fully go to sleep" but I really can't see what might sensibly be designed to take 40 minutes to turn off after you have locked your doors...

1.2A seems a bit high.

I'll leave it and have lunch now, and see if it goes down any more... Confused Very Black 07 HSE. Sometimes with added mud. Sometimes towing a boat. Always grinning.

Hi Bornslippy, once you lock the D3, watch your park break light.

When it goes out ( about 3 minutes ), your computers should be in sleep mode.

You need to see if anything else on. 2008 TDV8 RR Lux + 2009 D4 2.7

I've tried this a couple of times now and it's not going under 1.2A.
Maybe the tracker is using a lot for some reason ? Very Black 07 HSE. Sometimes with added mud. Sometimes towing a boat. Always grinning.

Namibia 2006 Discovery 3 TDV6 SE Auto Atacama SandDiscovery 3

Hi, if I use my Disco it is normaly for the open road, 400km+. That is once a month and now and the to town, 60km. Must say, I think thats not enought. What worry me is the Amps that is so high. I had my tester on for more than a hour and it stayed on 3,5Amps. Whats allso worry me is that the suspension go down with the battery. According to what I read, if you disconect the battery the suspension need to stay at that level, now could it be that the leveling solenoids try to level it and drain the battery? They replaced my driver side block and on testing it seems to be in order. I will just spend more time on all this, sure I will find the problem.

FWIW my Disco has not moved, been opened etc for 2 weeks.

The battery voltage before I opened it (Voltage measured at the towbar 12S socket) was 12.6V. Which is the expected voltage for a battery at rest.
