HI new member. Long time benz owner. I have read a lot of the threads on this still confused. Vin WDBUF56X57Bo98585 should be engine no 542314 witch is not in the affected range unless the range has changed.Generic codep0335. Am I safe from the dreaded camshaft balancer replacement? If so would I replace all 4 magnets with the new part no 2720510177? I have not tested by rotating cam to 305 degree. Any help would be greatly appreciated.
