Hi mate
Check battery for first, i think it creates a mess up when is coming flat :top:

i'd start by checking battery connections, then earths & ecu connections. mercs can be prone to body earth faults

Battery is new. I was thinking on poor earth too.

What it is Sam? Is it in engine area?

Print from diagnostic in attach. what is wrong with the car?
In Mercedes servis they told mi to change N73 (EZS)
but WIS told not to change N73 in case of code B1000, WIS say programmed module.

You can check your EIS car with Carsoft or Star.
Reset DTC from EIS. After that disconnect 30seconds and reconnect again Battery. Check again DTC if you have again B1000 you have to replace EIS.
