Steering wheel is off

[ld757]

Just wanted to ask if anybody has experienced the same problem. My steering wheel is a little bit to the left. When I am driving on a perfect pavement it is OK, but when I am driving on anything other than straight pavement, the sttering wheel always seem to be to the left. The more crooked the road the more it goes to the left. (as far as 5 degrees)
The car doesn't pull, I have checked it at the dealer and the allignment is fine.
It is really annoing, specially not on the straight pavement.
Do you know if this could be fixed, maybe I should ask a dealer to adjust it, if it is at all adjustable or not?
Mayne I am just comparing to my 2004 X5 4.4 where the steering wheel experience was completely different. My 07 X5 4.8 steering wheel is too light ( I don't have active steering) and reacts to any road surface, where my 04's steering was just perfect, but some people said that it was too tight.

Any advice?
