Same with mine, registration document C02 emmissions are listed at 216g/Km but can't say ive seen the blinds behind the grills. I got mine the same week as Fredo so ill have to check when im next back home

i have a week 48 build and don't see those auto blinds behind the grilles..

and i do have the auto-hold option too!!

For the benefit of others who may not have (Efficient Dynamics) Could someone explain what Efficient Dynamics is in some detail?

Fredo i was under the impression that some of the very early potentially ex demonstrators were not ED's aprox 3/4 weeks before the week 40 dead line..

I have a week 48 build and i have the shutters and auto hold too...

Quicksilver - Effecency dynamicis is basically an emmisisons change that BMW made to most of the range, "aparently" it means more performance with less emmissions, it has effected us here in the uk due to the tax banding of the vehicle...Any diesel X5 built after week 40 dropped below the 225g CO2 (3.0d now 216gCO2 previously 231g CO2) it lowered the anual tax on the car by £95 plus allows you to dodge the £25.00 london congestion charge and pay only £8.00, the SD model also dropped below this figure of 225 imposed by the government here.

BMW achieved it with tweeks to the aerodynamics and engine management although i cant see any aerodynamic difference with the pre week 40 builds...

This very small change will potentially have bigger impacts here in the UK than the US on residual values of the car... i hope this helps. if not check this thred for more info ...

im not sure what happened with the petrol versions to be honest.

Correct me if im wrong but i thought features such as auto hold etc were not part of the efficiency dynamics but just additions to the 2008 spec???

Thanks for all your answers. AS it has 216 Co2 it must be the ED model.

Just use the search feature:nanana:

Here's more

I am not fully sure but I think my SD is a production week +48. I noticed that my new SD does not have these "active air vents". Like the other guys here, its has autohold and it has a CO2 emissions of 216g/km. Hummm:(
