Good evening, I would to say thank in advance for any help. I am new to the Mercedes Benz copy. I am wanting to know if you change the valve body and conductor plate from one 722.9 to another one. What has to happen? Changed mine now the car will not start. Please can I get some help. Thanks again.

 

Need to virginize the used conductor, initialize and readapt. Or buy a new conductor plate from MB which only require initialization and adaptation. Or you reuse your old conductor plate which only requires readaptation.

The latter require Xentry and the former requires someone with tools and knowledge to virginize (still need Xentry for remaining steps)... not something authorized by MB as these are theft relevant parts. That’s said, the services exist.
