I tried starting my Land Rover 90 2.5 NA Ex-MOD after a winter in a cold damp garage. Turned the key to heat the glow plugs for more than 20 seconds, a smell of acrid burning and smoke started to come out behind the instrument panel. The car started but the orange light for the glow plugs does not go out and the burning behind the panel continues. Switched off the engine.
Any thoughts before I remove the instrument panel?
