The small amount of adjustment on a C-Class for alignment should not be able to correct for a front end that is pulling.
This adjustment is done with special bolts & "off-set" washers at the lower control arms. THERE is less than 1/2deg of CASTER adjustment available on this car. I would have someone look at the lower control arm bushings, as wear on these bushings will cause problems.
