W212 E-Class Car turns off while driving once a day
I am facing this issue since 15 days my car is turning off some days when driving first pick up goes followed by all systems shutting anf then the car just turns off while running. And when I scan the car it says in all modules high voltageScan report attached below I showed the mechanic but he is unable to diagnose without it happening infront of him and it does not happen everyday so it's a issue which can't be reproduced on the spot

thats a HUGE number of codes. When faced with a mess like that, I generally clear them all and see which codes come back first. if that high voltage thing comes back on, check the charging voltage when the engine is running, it should be between 12.6 and 14.6V, no higher.
but wait, that report says its a 2006 ?? huh, i plugged the VIN into Mercedes Parts, and the datacard says its a 2011.

I am not too good with software, but you have bunch of stored codes, who suppose to be cleared and recheck later.
The only current code who can affect driving I see is faulty CAN

I'm far from an electrical expert, but I can read and what I read is that your system voltage is toooo high.
Get the charging system checked, probably a bad alternator/regulator.
The reason your car is shutting off is that the fuel pump module is over voltage and it it shutting down the fuel pump.
