I just did a software update and it seems it solved some issues ( I hope ).
I did not receive any more suspension warnings ( which my Range Rover friends say it's normal when the temperatures are low ). The top speed became higher and the jerking on full speed desapired.
Also I always wait that the system check goes off and I think it helps.
( I'm a Apple mac user and I know how unstable Intel PCs are and that is what is controling our RRS )

On the other side the engine sound seems to be louder and and the board computer gives me less range on the same fuel amount ( full tank).

But anyway a great ride[/b]
