Hello, my name is ***** ***** I am a professional here at Just Answer. I have noticed that your question was not getting a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.

The problem you are having with the no crank condition can be caused by any of the following,

  • Anti Theft Malfunction
  • Battery
  • N65 Pulse Module
  • Starter
  • Wiring

    In order to determine the cause you are going to need to do some testing, I have enclosed the steps in the link below. Copy and paste the link to your browser to open and view them. I am not finding any listing for the fault code you have listed which usually means its not a valid Mercedes Fault code.
