So say the engineers from Stuttgart.
It's isn't electrical supply problems it the failure of the SBC system itself.

I have not been through a failure analysis to determine root cause failure analysis as a customer. That is MB engineering's job. But if they want me as an Engineering Consulatant for a LARGE FEE I will gladly tear into it for the failure mode. But then they may not want to hear what I have to say. After all it is German Engineering.

This is absolutely pathetic in all honesty. This gives me even more reason to doubt the Infamous W211 SBC braking design.

If one became available, I'd probably install it. I'd say SBC was a case of over-engineering a solution to a problem that didn't exist.

SBC Failure STOP

The Issue has not been fixed because the dealer could not duplicate the problem. I dont drive the car simply because i feel its a death trap. I would like to just sell it but who's gonna want a mercedes when i tell them "Also the brake s might go out occasionally".
