2008 Mercedes R350 nothing happen when ignition on
I checked all fuses they seems ok
Battery OK has 12.5V
So when ignition is turned on nothing no light on dashboard
gages does not move only clock works .
key in ignition turns no problem but car completely dead .
Of course can not shift it from park to neutral
scan it with diagun ECM,TCM and some more module does not recognise
instrument cluster shows no errors
when trying to activate gages or light no work
SAM module no errors but activation test fail .
Can you guide me where to start please
