MERCEDES STEERING LOCK NO FURTHER A MYSTERY

Unlocking and locking car is effective. All other electrics do not operate. Batterie is ok, fuses are also Okay. Do you're thinking that it may be the ESL or maybe the EIS. In case the minimal motor within the ESL device is damaged and I set in a completely new motor do one should reprogram ? I observed your video and know how to take out the ESL.
