SBC hydraulic unit warranty about to expire, failure symptoms? - Mercedes-Benz Forum Post #64
People can die when this happens yet some wish (for an unknown reason) to think it's the drivers/owner's fault.

Please quote posts where anyone in this thread ( or PP site ) suggested that a sudden red is the drivers fault.

I still think it would be prudent to replace the SBC as soon as you buy a car with one in it... If you chalk it up to maintenance costs over the course of ownership its not really that much, especially for the piece of mind...

Will someone with a BW account please have the sudden red / shutoff guy post the actual trouble code that triggered red / shutoff. Also, have them post the number of actuations and the i_vzz and i_vzzMax info outlined on page 6 of the BW link. Partial quote below:

Quote:
There is one procedure that I've run in STAR that may be relevant. It is "Check operating time of component (SBC hydraulic unit)." When I ran that procedure not long ago what I got was precisely:
i_vzz=22282300
i_vzzMax=59801600
I don't know if this is telling me that I'm not yet half way to the red zone or if it's something else altogether.

There's the white messages with two different messages, and then there's the red message with SBC failure.

If you get to the point where the SBC fails, you've been basically ignoring the previous message. It shows up EVERYTIME you start the car. You'd have to be blind and deaf to not notice the beeping and the cluster message.
blind and deaf driver/owner?

owner intentionally ignoring ?

Plenty of driver/owner blaming here. Bosch and MB spend nearly a billion on the SBC and then shortly into it they stopped using it. Why? It can fail without warning and cause a catastrophe.

You don't comprehend the question I posed, read it again slowly. " Please quote posts where anyone in this thread ( or PP site ) suggested that a sudden red is the drivers fault.

Sudden red as in: Everything was fine , no white messages, primary brake system shut down and the dash went red.

The driver / owner is being blamed if they _CONTINUE_ to drive the car long after white warnings were issued or the system has gone red. Same goes for driving on a punctured tire / steering linkage worn out / . .. . .

When a regular brake system suddenly malfunctions due to a failed master cylinder , rusted steel line, brake pad becoming unbonded from the backing, rubber hose rupturing, are there any warning lights that turn on before there is a failure?

Apply data and logic not blind emotion.

Don't autoscan all systems on your Cdi while driving. I was surprised the Maxidas scanner I have would do this on my car. I was pulling out of my driveway when the Sbc scan came up. My brakes totally went out , dash turned red and I couldn't stop for a second. I was just moving the car to a different spot and was ready for this to happen. I was shocked it would perform a scan that would take out the brakes while driving. Bad software programming there. It should say -- put car in park ... Turn off engine -- something. I warned you. And really never scan your car while driving unless the manual says too.

Maybe not, what does the scanner manual say about running a SBC scan and driving the car?
