SBC Usage Reset

[spenttherent]

My warning came on at about 168k

MB reset it and told me if it comes on again it will need new software at the price of £132

Those are low values, if compared what one indie mechanic said in FIN forum, he said usual mileage >400 000km. Counter values have been between 350k-550k cycles. On the other hand, distances in Finland are long, no much traffic - perhaps less braking events needed per mile. I have 376k in my counter (no alert), 180 000 km but car has been7 years in Germany.

Forgot to add. The only number which really matters - the counter value - was approx 417,000 in my case.

Mine has done 90K+ and is just a bit noisy (I think).

I have decided to wait until it turns up its toes. My mileage is all motorway work, hardly any braking. I ended up not poking about inside the new SBC unit. Didn't feel it was worth the risk. The Hardware has been upgraded as well as the software. Wasn't sure if valves / modulators have been changed for lower voltage or current types. As advised by STAR, I felt mixing and matching was not a good idea. I have driven my car a few yards with SBC switched off. Take my word for it, you don't want to be doing it at 70mph, there are effectively no brakes!! It is a sure fire cure for constipation.

I think the pump can certainly be swapped over but I would not like to go any further than that! New SBC unit is back in its box!

Cheers.

Well, my reset device arrived from China in record speed for the princely sum of £44 including postage and... It works like a charm!

You plug it in and wait for a bleep. Then you have the option of pressing one of 4 buttons; 25%, 50%, 75% or 100%. This is how much you want to reset the usage counter by.

I pressed the 50% option, after about 15 seconds of bleeping and red "No Brakes" signs in the dash (which I must admit was a bit alarming!) The normal display came back and the blue LED lit to say it was completed.

Checked the car, waning gone, no malfunctions

I'm very happy to get some more life from an otherwise perfectly working unit. There are several other sensors to detect problems with the brakes so merely resetting the usage counter doesn't phase me and at least I can confirm this definitely works!

Here's the link for the one I bought: http://www.ebay.co.uk/itm/111148488386?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649

It would be nice to know how often these reset devices can do the job (to same unit I mean). Because there was a discussion where was said that even with star, the reset can be done only twice... ,now if this rule apply you cannot make reset -25%, -25% and -25% (I bet no one want try that with their own car? )

That device will be doing the same as SDS in Dev mode, resetting the operations counter. This is just for the C249F error.

I have heard that you can only do this the one time, but looking at how SDS works, I don't think there is a actual limit, more a limit that MB are willing to carry out.

One Finnish forum member (why I have a feeling that I'm using that phrase all the time nowadays ) tried and failed to reset his unit second time (or third, really cannot be sure anymore ), but of course it's possible that there has been other matters which prevented the reset. Like BlackC55 in other forum said, reset is succeeded only some % of the units even at the first time. Again, it's not known what's the original reason for unit fail, why reset is failed, other major fails or what. When thinking, pump cycles and duty cycles will definitely increase if there is troubles in pressure production (leaks, motor electrics etc.).

Edit: maybe there is a hidden counter for counter reset you'll need a developer's developer mode = god mode to reset that

should I buy one or not?

should I buy one or not?

If you have a W211 or an R230 and you want to reset the SBC usage counter to get rid of the error nag, then yes. If not, no

did you have to deactivate the sbc system before using this tool and then re-activate it once the fault was cleared?

did you have to deactivate the sbc system before using this tool and then re-activate it once the fault was cleared?

For Mercedes Ben z's Safety Precautions had stated that before attempting to repair the brake system on its models W211 (E Class) and R230 (SL Class), the Sensotronic Brake Control (SBC) system must be deactivated first using its STAR-DIAGNOSIS tester.

Deactivation of the SBC system is absolutely necessary before carrying out any maintenance work onthe brakes like changing of pads, discs and fluids because the system is under a pressure of 140 bars. Mechanics who perform brake services on these car models must have the proper tools to avoid the risk of injuries to themselves and damage to the brake system.

Until the introduction of this inexpensive, convenient, light, safe and easy to use SBC tool is another alternative to the STAR-DIAGNOSIS tester when working on SBC system. It can perform the tasks equally well which is efficient and safety.



After the repair had done, the SBC system can be activated and restore back its pressure. The memory is erased automatically.

The tool does all that. You see it deactivate the SBC system, reset the counter then re-enable it again. Takes about 15-20 seconds.

Or you could just go here & pay £100-00

Nothing to do with me I might add, just spotted on E-Bay

Same thing but they do it for you.

Can't imagine why anybody who knew about the reset tool would pay someone £100 to do it when you can do it yourself in 20 seconds for £44 and still own the tool for future use!

hi all ,reading with some horror about this pump. can i change this fluid myself ans bleed the system ,? is there a set proceedure ?

 

[gizze]

Bosch are now allowed to supply the SBC units direct, so no longer have to go through Mercedes at £1200+vat.

I hope they know which pump fits what as they are different for certain chassis breaks on some models.
