mercedes w204 defective ABS sensor displayed at the rear right

mercedes w204 c220 170ps bj 2009 read out device shows ABS rear right at sensor exchanged 2x ATE and once original mercedes, problem still there. Cable was also checked and the whole rear seat out but the cable is fine. then the wheel bearing was made and the problem is still there, I got rid of 850 euro. the car is jerking in the first gear extremely and in the second gear from time to time especially in a right turn. Can this lie on the ABS block or has the control unit e inen weg ? I would look forward to news that could help.
