Hello, I appreciate that I am new here, but any help would be greatly appreciated.
My 2001 TD5 Disco has been off the road for around 4 years, stood outside. When it was first parked up it started fine and had a full MOT.
Tried to get it started again but a significant part of the electrics isn't working. Key in ignition and turn it - all of the warning lights come on and then gradually go out except oil light, battery and the S&M lights flashing. There are six bongs and the gear indicator is flashing with what looks like a D with a line through it. Immobiliser light is blinking all the time.
The following are working: radio, heater, windscreen wipers, horn, screen wash, electric mirrors but everything else is dead.
So far, I have fitted a new battery (a good one recommended in another thread on here), key fob is working, cleaned out ECU red plug, checked fuses in the engine bay, cleaned the three earth fittings next to it - but I will be working through other earth connections.
I know that the damp has got in over the years through the sun-roof and so I think it might be a dodgy earth lead somewhere?
If anyone can help, it would be much appreciated. many thanks.

Welcome to the site.
Check for water ingress behind the glove box. It sounds to me as if your BCU is dead.
I suggest you post this in the Discovery section where more D2 experts will be likely to see it.
