Please help! Freelander 2 2006 Weird electric issue

Hi guys.
I'm having an issue with my Freelander 2 SE (LR2) 2.2 TD4.
After Christmas break for 2 weeks, tried starting it and it just turns the hazards on, temp gauge to max, locks doors and doesn't even attempt to start.
AA came out and read codes, said that it thinks it's been in a crash, tried to clear them but they just came back straight away.
Battery is full and good (replaced 2 months ago and shows healthy voltage).
Tried a few battery disconnects. Tried unplugging the 3 ECU plugs aswell.
Any ideas on where to start? Probabky going to an auto electrican at this point...
Tempted to hot wire to starter to atleast get it running?
I tried to upload video but can't for some reason.
Thank you
 
If CRASH status is set, then only LR diagnostic equipment can remove it.
This status is set when the BCM registers a battery voltage drop quickly below 8.5 Volts. This can happen when the battery is very low, and the starter pulls enough power for the battery to plummet below 8.5V.
Once set, the hazard lights will flash, the door locks will attempt to unlock, CRASH will be displayed on the LCD briefly, and the engine and other systems will shut down.

The way around it is to fit a new and fully charged battery, then cycle the ignition a few times. This will allow the various systems to boot up again, although the CRASH status will still be set in memory, until it's cleared by LR diagnostic equipment.

Are you sure the starter is functional? as it should still start ok once the battery is fully charged and the ignition has been cycled a few times.

What ECMs have you unplugged? Just unplugging random stuff is a sure way to screw stuff up. These are seriously complicated and heavily electronic vehicles, so various modules are best left alone unless you are sure there's an issue with them.

Cheers for reply.
There's no "CRASH" on the LCD display.
Starter worked 2 weeks ago absolutely fine - What's the best way to test this? Direct to starter with battery?
Sounds like I'll need to take to Land rover...
Unplugged the engine ECU at the back of the engine as recommended by AA and a few forum posts I found - hopefully didn't do any damage...
