Hi Friends !
Mercedes W212 16 year, I replaced all the airbag and the positive battery terminal, watching the MB Star no errors but the starter does not run .

All fuses good !
I checked !

All fuses good !

If got star then use it to check for start authorization if all is good then nothing hold it back and then just check starter.
