engine not starting

[c320]

My c320 sometimes will not start? i get no error message but when you turn the key nothing.

Then it just starts and i will get a esp message telling me its not available? I turn off restart and all is fine?

Battery seems fine - all electrics are working etc.

Any ideas anyone?

Ok, you have transition resistance on the contacts of the ESP control unit, this leads to an offset error in the brake preasure sensor.

You can try cleaning the contacts with a good switch cleaner but the only long term fix is a modified wiring connector to the ESP control module.
