The tachometer "spring" just sits there

[Ferguson]

I'm confused.

I've read several postings that talk about the "spring" on the tach, the hashed lines above the red line that are supposed to move to indicate, on a cold engine, where you should not rev.

Mine never moves.

There are 4 lines shown, they sit there. They are the same whether the engine is cold (well, as cold as it gets in Florida) or been running for hours.

I read another post (which I cannot now find) where someone said this feature no longer existed, but I clearly have a recessed area around the tach and the hashed lines are there, they are just static.

Broken?

Does anyone's on a new-ish X5 move? mine is a 4.8L sport 2007 built sometime summer 2007, delivery in mid-July.
