Silly question , but have you checked that your brake lights are working. AFAIK the car uses the brake light circuit to check that the brake has been applied , which it wants you to do before allowing you to take it out of park

It seems to think it's in Crash Mode with the hazards on, it does this automatically. Not sure what might have triggered it though.

Crash Signal
When the restraints control module outputs any of the
fire signals, it also outputs a hard wired crash signal to
the Engine Control Module (ECM) and changes the
high speed CAN bus output message from 'no crash' to
'crash condition'. The high speed CAN bus message is
used by the Central Junction Box (CJB) and the Fuel
Fired Booster Heater (FFBH).
On receipt of the crash signals:
• The ECM disables the fuel pump.
• Operation of the FFBH is disabled.
• The CJB enters the crash mode and:
• Activates all of the unlock signals of the vehicle
locking system, even if the vehicle is already
unlocked. After 3 seconds, the CJB activates the
unlock signals again, in case a lock button is
pressed during the crash, by flailing limbs for
example.
• Ignores all locking and superlocking inputs until
the crash mode is cancelled, when it returns the
locking system to normal operation.
• Activates all of the courtesy lamps, except for the
approach lamps. The activated courtesy lamps
remain on until they are manually switched off
at the lamp unit, or the CJB crash mode is
cancelled, when they return to normal operation.
• Activates the hazard warning lamps. The hazard
warning lamps remain on until cancelled by
turning the ignition switch from position II to
position I or 0, or until the crash mode is
cancelled.
The crash mode is cancelled by cycling the ignition
switch.

Daft question but is your battery flat or low

No, that would normally do it unless one of the crash sensors is permanently giving a crash signal.

Can you remove the battery & then attach that by jump leads to your other car in the garage? If you then run it for a while, it should put some charge into it (unless of course you have a battery charger) 8)

would also give the Disco time to completely lose any rogue signals. Also touch the positive and negative cables together for 10 seconds on the Disco (obviously with the battery disconnected!) that'll also clear any spurious signals i hope.
