If the alignment is right and the caliper is releasing.... the only thing I can guess is radial pull.

Radial pull is completely out of the way, two sets of tires has been balanced several times using the new balancing machine type at the dealer.

Caliper release: only visual so far. How can I thoroughly check this?

If everything appears to be in spec, you can try adjusting as recommended by Mercedes for the W203 C class (follow these links):

Jack the right front up and see if the wheel spins freely.

So I need to add +1 degree caster to front passenger side? I need to buy chamber plates? I thought these cars have variable chamber because of the lower control arm.

As you've now gone through 3 sets of tires, I'm inclined to eliminate tires as a cause of your pulling problem (and I have some background in tires and tire "pulling" issues). It would be rather EXTRAORDINARY to experience a pulling issue due to tires after going through THREE sets.

If you had mounted a NEW set of tires and experienced pulling where it didn't exist before, I would be SUSPECT of the tires...but this is not the case here.

I think we can eliminate the tires in your case.

The only other thought that I have is that a LARGE difference in castor from left to right (alignment) may cause pulling...but this would be highly unusual on a BMW.

It seems very odd to me that your steering wheel is centered as you experience this pulling sensation.

Good Lord! Keep caster identical, side t'side. Remember to check toe.

Front end camber relatively un-adjustable. Not that it wouldn't be a kick -- -2.5 neg camber's a hoot. So's tire wear, a diff kind o'hoot....kindofa agonized shriek.

Your problem isn't caster, judging from alignments past. Look deeper. There's a reason the previous owner is.

That's what I thought. The Mercedes links above state that +1 caster change. I doubt that would work with our cars.

Yes, tires could be eliminated definitely.

@pointandgo:
As the car pull to right, the steering wheel turns with the pull.

Any issues with tire "conicity," (built in to the tire due to steel belt offset) would result in a steering wheel offset if the "bad" tire was on the front - steering position).

I can't see that this is a tire "conicity" issue after THREE tire changes. It would be highly unusual.

New revelation:

I had the front wheels off and spun the rotors. Front right rotor seems to be warped and worn out and seem to be catching the pads at one point of the spin. Overall there was a lot more resistance in that wheel compared to other side. I will be replacing pads and rotors soon. Just hope I don't have to replace the caliper or the bearing for now.
