Delete SBC?
I searched but i couldnīt find any info on this. Could the SBC system be deleted?
The facelift W211 came without the system. Is it possible to have an SBC car converted to the facelift system?
Might be a dumb question but since iīm no engineer, might as well be the one to ask.

SBC is Traction and Stability control along with ABS and the brake proportioning valve. There isn't really a master cylinder and there isn't a brake booster. The pedal assembly would have to be changed out since ours is a hall sensor with a feel simulator on it.
At least 6 ECU's are tied into the SBC....
Any more questions?

So, short and concise, SBC is so integrated with our cars that itīs impossible to delete it for a reasonable amount of time and money. Might as well buy a new SBC unit if the old one burnes out. Thanks.

I also believe that there were structural changes to the firewall when they went away from sbc. I don't believe a standard brake booster will even fit. Having never tried, I'm only assuming though.

my full plan is to remove the drive train ( 2.7 CDI & 722.6 NAG1 ) and replace with a Cummins R2.8 crate engine and 6speed Eaton fuller fso tranny I only wanted to do the tranny, but since the ECU depends on input from it, it seems the five cylinder will never run without the AT
My biggest questions are compatibility with other systems without the ECU sending its data
this is in 2005 Mercedes Sprinter 3500 RV

Electronically, you have the SBC ECU itself, which is wired up to the ESP ECU (ESP acts as a CANBUS Gateway for SBC since on Maybach Cars, there are actually 2x SBC ECUs which ESP will take to directly to regulate braking on each side of the vehicle).
On the facelift cars with a more conventional ABS pump, the ABS unit acts as ABS/ESP in one.
Now due to how unique the SBC system is, multiple other ECUs have specific software on them to work with the SBC module:
1. Engine ECU (ME/CRD)
2. Gearbox ECU (EGS)
3. As mentioned before, ESP
4. Cluster (KOMBI)
5. Gear selector ECU (EWM)
if any of these ECUs detect SBC not present, the car will enter a failsafe mode.
Now my write up here is just on the software side of the ECUs. I'm not even considering the physical restrictions mentioned by others here (where to put the brake booster, the fact that there is no vacuum system etc...)
So yeah, it's impossible. Well, at least without super advanced knowledge on how these cars work. Even with what I do, I'd never consider doing this, it would open up a can of worms even if somehow I did get it installed and working (for instance, no ABS module has the programming or the calibration for our E55s braking system).
Just keep the SBC system, and if your worried about it's life, get it overhauled . Please for the love of god, do not use one of those Chinese SBC reset tools. I'd be more than happy to explain why, just not in this post

Everyone gets funny with these SBC systems and I must admit I was too when I bought the car, and 10 years later my new unit is still sitting on the shelf.
These systems work VERY well and can generate huge amounts of brake pressure to bring these cars to a stop from very high speeds. To me it's the least of my thoughts with the system failing as my rotors turn purple and the calipers are now a dark red from the heat...used tp be bright red so SBC ok in my book !!

When it does fail, it isnt good. Just like all Mercedes, they work well until they fail mostly catastrophically. If it was such a good and safe system, it would still be in use today, but it isnt the safest engineering design.

It can be done on MY 03 & 04 but after that too much computer integration. Now this guy right here took it next level with a drifter handbrake even:
not sure why youtube link won't show but look-up 'dapper drift' to see w211 drift car w/ hand-brake
