the cdl neutral warning light on the dash will come on in an '03 disco when the t-case is shifted into the neutral position. (gear wheels with an x over them.) i believe this light is orange.
the cdl UNLOCKED warning light on the dash should not come on in an '03 disco unless it has had a lockable t-case installed. this light is the red "tie fighter."

I would say there's a good chance the transfer case may be trashed. I have no personal experience driving in Low more than a handful of times at low speeds (traversing soft ground for a couple hundred feet), however this is taken from the owners manual"
Low range (‘L’)Low range should be used ONLY in situations where low speed manoeuvering is necessary, such as reversing a trailer or negotiating a boulder-strewn river bed. Also use low range for more extreme off-road conditions where progress in high range cannot be maintained. DO NOT attempt to use LOW range gears for normal road driving.
Hopefully others can offer some additional real world experience using Low range.

From what you've described, sounds like the t-case has failed. Either have someone who knows Rovers check it, or start the removal process so you can disassemble and see what's going on in there. Great time to get a case with CDL function if you'll use it. If not you can get a non-CDL cheaper or rebuild yours.
i guess it’s time to brush up on the transfer case, lol

Whenever you have the TC N warning come on at speed you should technically put the transmission into N as well and coast to a stop to prevent any damage then pull the 4WD shifter fully back & then place the transmission into D & see if it moves & the amber TC N warning light goes out. From the sound of it the TC sounds low or out of fluid, and possibly burnt up. The linkage is a cable and it “could” be binding, but the noise you decribed sounds like it’s internally trashed.

Its okay...There was some malfunction somewhere, because the hi low lever was never moved by a human, and all that was required to deactivate the chime on first occurrence was a slight pulling pressure on the hi low shifter. The second occurrence was catastrophic.

TC’s on RRC/D90/D1/D2’s all seep and a lot of them never get checked regularly & then when they get low they run hot & bearings, gears don’t react well to that. I’ve replaced several customer TC’s that were burnt to a crisp inside due to no lubrication.
