Hi, I lost power steering, ESP, ABS and tyre indicator on my C220. I had it put on a diagnostic and it came back as 50001 N30/4 control unit internal fault. I took the module off and set away for repair. They have come back to me and said there is no fault with the module. Now I'm stuck. Any help would be appreciated
Fault Code 50001 N30/4 Please Help

If it is W204 , N30/4 is ESP control module (next to brake pump). Check the wires and connectors. Also ABS speed sensors on all wheels.

I took the module off and had it tested, came back fine which is puzzling. I will attempt to check speed sensors....not something I have done before but I will have a go
