SL55/63/65/R230 AMG: Top works, trunk soft close too, why no central locking?
My next step would be to check the system with Star Diagnosis. I would see if any faults are present, and I would see if the pump can be actuated to lock/unlock the car from the PC. Those steps would prove conclusively that the pump is faulty and needs repair or replacement.
