Ok, I changed my order to and SD, got the automatic supension with it.
I used to drive a 320d tuned to 200hp and am now driving a car the dealer leased my whilst waiting for the X5, its a 318d. Car is nice, but it's missing a lot of horses ;-)

In belgium we have the choise to remove the sports suspension, but I kept it on. Anybody thinks this supension is to "hard"?

Can't wait to get your feedback on the SD's!

@DutchX5: Could you send me some more info on the chip your ordered?
