Just had a call from the dealer, I think they are going to try changing all the Dunlop 20" RFT tires, I think they are just changing things for the sake of it.

They put 18" wheels & tires on it last week and it still pulled to the left, so changing the tires won't work.

The fact of the matter is the distance between the front left & rear left wheels is less than the distance between the front right & rear right wheels, this is fine on a LHD car but on a RHD cars this needs to be reversed.

The problem with the X5 is they have not allowed any adjustment to occur to pull the left front wheel forward and push the right front wheel back and with the combination of Adaptive Drive & Active Steer as the car remains level at all times when driving through corners & on straight roads.

Also, when the X5 on a slanting road (slants to the left) does the Adaptive Drive actually keeps the car level and thats where the problem is coming from. Is it jacking up the lefthand side of the X5 and droping down on the righthand side to keep the car level, thus changing the suspension settings which because of the present castor settings makes the X5 pull left. The whole lefthand side of the suspension alters when you jack car up, you see it when you change a flat tire

A normal suspesion X5 won't show the problem as the car does not remain level when driving through corners or on uneven roads.

It boils down to the fact that no testing was done as the these RHD cars with Adaptive Drive & Active Steer were only just manufactured in mid May 07 and they had not allowed for the opposite camber on our roads. I think they just got caught out.
