Thank you again. I have removed the glovebox and find condensation on all the units inside, so that probably to problem. I guess first port of call is to put a heater in and try to dry it out?

Thank you, I'll certainly take a look at the BCU & IDM - especially as it's been very wet and the truck has been standing. It's a shame because I thought I'd found my forever Landy, considering the very, very low mileage (genuine). Regarding my introduction I have filled in the details required...

Thanks for that. I was hoping for an easy fix but looks like a trip to the vet. I don't have a computer/analyser.

Yes.

Left my 2003 Discovery 2 for three days, came back and won't open with radio key. Can open with the key with no alarms and a padlock showing on the warning lights (Immobilised?). Battery good, lights work but indicators or hazards, engine obviously dead. Checked fuzes. Any help greatly appreciated.
