I have been considering purchasing a FL2 for a while now but in light of this and also the PAS problems i'm seriously having doubts that another Land Rover is the way to go which is a shame!
I've had this problem twice. Once below 50K and again at around 95k miles. Both times the dealer has repaired it using their fix rather than fit a new rear diff. Thankfully both times it was under warranty, but, I fully expect to keep my FL2 for another 50k and have this go again at some point. Overall, it has been massively cheaper to run the my previous Audi A4. Other than this it hasn't missed a beat.
