air suspension button???

[mariosp]

Hello!!
According to my last post, finally I will go over the X5 11/2003, fully loaded with extras! but the dealer insist that the car has as an extra air suspension,

I went to a BMW specialist engineer and his computer showed in the field of air suspenion off,

In the back of the car in the space where the extra tire is located there is the mechanism of the air suspenion and pumps (that the specilist told me are)

I wonder why the computer doesnt show the air suspension and also I would like to know how it can be seen in the car , is there any button?

I hope you understand me

Thanks
