I'd love to know how they did a proper 4-wheel alignment and the car still pulls to the right UNLESS the frame is out of alignment vertically (one corner higher than the other three). Even that ought to be obvious, and I cannot imagine an MB dealer service department releasing a know problem car with the problem still there WITHOUT telling you, or well, with my experience with MB dealer, I can. Take it to a good independent shop, they are sometimes better. A very good body shop with experience in frame straightening might be even better.

Lowering tire pressure on one side in the front having that much effect makes me thing something still isn't correct.
