I noticed my 05 V8 SE had this issue just over a year now and has gotten bigger present day. Extended warranty wouldn't cover it. Said it was cosmetic and the airbags wouldn't deploy because of it.
Spoke briefly to a LandRover dealer service advisor and was no help at all. Just said "It's real expensive to replace, around 3-5k" what a ****.
Spoke to my local mom and pop LandRover shop where I get all my stuff done and they said a used one would be about $500 dollars plus install but they couldn't gurantee that the replacement won't crack later down the line. He said he looked around in forums and other folks are trying to fit and LR4 dash instead.
Any online LandRover salvage parts shop also quoted me $500 but if they had some in stock.
Spoke to some uphostry shops and they all said it can't be fixed. The filler they would use will just unstick depending on the weather. If you noticed in hot weather it will seal up and disappear and once temps drops it will reopen. They said it would just get worse.
I might eventually break down and just get a salvaged one. To me it's more about knowning it's cracked and being and eye sore to look at for a LandRover of all cars.
Pics below are from late last year. The cracks have gotten bigger since.
