I have a 2011 w204 c class.

I'm really happy with it but the handling is very odd and I was hoping other owners could tell me if it's normal.

I do a lot of motorway driving and I find the car is constantly pulling in one direction or the other.

When the road cambers or if there is any crown in the road, I have to steer into the camber/crown. In order to drive in a straight line, It's as if I have to keep the steering wheel level with the horizon as the car rolls with the camber/crown. Is this normal?

It's driving me nuts. On occasion i have to use opposite lock on very shallow bends, where the camber is pronounced.

If it's not normal could anyone give me advice as to what may be wrong?

Cheers in advance,
Luke
