a non red brake message dash indicator?
Hi guys,
I recently got this message today on the dash on my 04 E55.
From what I have read it's either my SBC unit is nearing the end of its life or the switch under the dash is the problem.
Has anyone else received this service message before?
Thanks!

$121 on FCP Euro or RM European has them for $87. I paid close to $200 around a year ago, they've really come down.

no code with reader
Hi guys,
Thanks for all the help.
I hooked up my OBDII reader to the car and no codes are showing.
The message is on the dash as soon as the key turns to the on position.
It does not go away.

You aren't really gonna know what it is until you can get a star scanner hooked up to it. Until you do, you are just gonna be throwing parts at it. If you want to try the switch, I remember it being <$30.

Assuming it's the open circuit failure mode:
If you have Keyless go, it simply won't work.
If you don't, you can get to it pretty quickly and manualy short/open the switch. Opening it is quite annoying (been inside, took a while without breaking it), so it might be easier to just bare some wire and momentarily short.
Use your imagination.

I had the same message. Thought it was a sensor as I had recently done new pads/rotors but didn't replace both sensors.
Turns out it was the SBC pump itself that had failed. Dealer indicated I needed a firmware upgrade and after they did this it tested OK. They didn't charge me for the upgrade but I think it was only $75 if they had.

Owning a car like this you really need a star system,i have used it a lot during my 6 years with the car.i got that brake message a while ago and for me it was that the SBC had reach its brake activation limit,after 300000 brake activations it sets a code (c249 i Think)and the sbc need replacing,the brake counter can be reset but is definitly not recomended,if you value your Life!! sounds strange that the sbc need a software update after 13 years.

When I came back they told me the message was due to SBC pump failure. They then did the firmware update (I'm assuming this was a re-flash of the ECU) and the pump started working again.
They actually didn't even end up installing the wear sensor. The told me that the one I didn't do was the "50%" one and they don't even install those anymore.

In the mean time I found a shop that'll do a star readout for 60 bucks. Will keep you guys updated on the progress

Well, you have more or less 3 options then, buy a rebuilt SBC unit, rebuild it yourself, or reset the internal counter on it with a cheap Chinese tool and hope for the best. The last option is obviously the sketchiest. Rebuilding the unit, from my understanding, is really just replacing the brushes and accumulator and resetting the counter.

Getting the "Brakes, visit workshop" message on a '03 W211 E55.
The dealer checked it and wanted over $2000 (USD) to replace the SBC pump.
Shouldn't this be covered under the MB 10(12?) year unlimited miles SBC Pump Warranty?

I had the C249F error I pulled the pump opened up the pump motor housing replaced the carbon brushes(5x5x13) soldered in new brushes, also replaced the pressure accumulator with a new one at the sametime. The brushes still had quite a bit of life left in them but I accumulator was starting to lose pressure, reinstalled SBC unit, bled the brake using Star and a motive bleeder this took longer than rebuilding the SBC. Once complete everything tested okay I then reset the SBC counter, all up cost me around $300 NZD to rebuild not overly difficult if you have the correct equipment and tools the dealer wanted $3500 to replace the SBC and install.
I talked to one company that does rebuild the SBC pumps some only reset the SBC pedal count others offer a full rebuild service which includes new brushes and new accumulator only if the existing one is not within spec the valves I was told are never replaced and if they do need replacing the units are deemed to uneconomical to repair.

Just online they are just standard electrical motor brushes pull the old ones and take an exact measurement as later model SBC pumps had larger brushes.
Mine were 5x5x13 in size you will have to solder them into the existing copper braided wire.
