Range Rover Sport 2008 - suspension failure

[Sym7]

My RRS 2008 has just presented me with a red fault light stating suspension failure and to switch engine off. The thing is, it looks and drives perfectly well (2 miles back to girlfriend's house). I live 70 miles away but not sure if I should drive it back or not. Other forums say it's a sensor etc.

I'm keen to know or hear any suggestions as I know very little about Range Rovers. Thanks.
