Yet another W211 with a SBC failure
There's 2015 C-300 4 cylinder engines with 200 miles on the clock getting engine overhauls. Product defects are present on all makes and models. It's just when it comes time to address or pay for them people want to wave the lawsuit flag/this is a safety issue/it shouldn't be like this ect ect. To each their own, however if you are really that unsatisfied with your you MB or any vehicle for that matter-sell it and get you a TOMOS moped or VESTA. You gotta pay to play and Especially when you drive something with a MB on it!!!!!
It's one thing to purchase a MB-A COMPLETELY DIFFERENT THING TO MAINTAIN AND TAKE CARE OF IT.... product defect or not....
I never whined about anything. I was attempting to learn more about the issue from others who have had the unit replaced; so that I could determine if it was worth it to me to pay for the repair given that the car is older and isn't worth too much any more, I was planning on replacing it in 1-2 years, and that I'm uneasy driving it now.I took the advice to take it to an independent shop, got a quote for $1600, and decided that was worth it to me. You admitted that you replaced your w211, because the SBC failure was lurking in the back of your mind. Well, it's lurking in the back of my mind too.
I'm not complaining because it's a expensive item to fix. I had more costly problems than this with my previous C-class. You buy an expensive car, you should expect expensive maintenance.
I understand that conventional brakes fail too, without warning. But this is a chronic problem with a specific system and MB didn't put sufficient back-up braking capacity in the car, despite what they say. You all aren't getting the point of my argument, and I don't know how else to explain it... so
Shadow5501, I never got a white brake system warning. That would have been nice. In my experience, even after it completely failed, it didn't post any fault codes.
This is good to know! How do you check it? Do you have to have DAS?
Perhaps the result of a class action could be for MBUSA to provide free diagnostics/evaluation of the SBC for the life of the car at some determined regular interval. Only free to encourage people to take their car to the dealership, then they are free to take it to whomever for the work.
OK, I've officially spent too much time on this topic.
This wasn't directly appointed to you-this thread-or topic. I was more-so saying the cost statement because I frequently see people complaining about costs all over this forum for repairs.... Like did you die? Did someone put a gun to your head and say you have to purchase this BENZ?

NYSMITH you did the correct thing in fixing your sbc especially since they weren't going to offer you much for the vehicle. Bite the bullet, like you said aside from this things have been great, and fix the MERC and get it back on the road!!!!

I plan on replacing the SBC when I hopefully get the white warning stop sign in the dash.
We all realize that parts fail. What is an important difference is that this system apparently has a PRE-PROGRAMMED service threshold, which when attained, shuts the system down to a backup mode. The backup is less than adequate according to forum members that have experienced the failure.
Owners with a DAS can interrogate, why can't the dealership? MB should instruct their mechanics how to interrogate and issue a recall for a free check. I am willing to pay for the replacement before the failure occurs.

action lawsuit, wanting a recall, sounds like whining to me. When something fails in your car, get advice on how to handle it the cheapest possible way then move on. Thats what this thread was about up until my first reply. But when people start chiming in about lawsuit and what not, this thread has become a whining thread.
Show me an article that an sbc was the particular cause of death of an accident. NO ONE CAN. Full stop. Now tell me how many W211s were sold all over the world from 2002 compared to all the documented complaints about SBC. I understand that not all 211 owners whine in forums about their problems with sbc, but dont forget that not all 211 owners post their JOY and SATISFACTION with the sbc too.
OP: i fully understand your situation and i will be scared as well, but stop bein a baby, you got your advice, good ones if you ask me, fix the problem and move on. There will be more problems thatll youll encounter with your mb and youll need this forum again. When the time comes to upgrade, go for it like i did. People here a very helpful and knowledgable about MB, but some just get tired of pointing the blame or looking to pass the responsibility to someone else. Again, goodluck and like most of us here, hope you enjoy your 211 til your next MB. Cheers and happy motoring!

I throw the BS flag on this one and call a penalty. If you want to rub this so-called "Service Advisor"'s nose into it, give him a copy of the following. Absolute rubbish on his part. If he doesn't understand it, tell him to join this forum and search.
--------------------------------
W211 SBC countcheck or reset (Must have "developer kit" software).
Start engine. (Note: Engine does not need to be running to only obtain count.)
Start Xentry, go through menus for your vehicle and go to:
-Control units
-Chassis
-SBC sensotronic brake control
-Development data
-Actuations (should be at the bottom of the menu so scroll if necessary)
-Complete index of Actuations
Break: To only get the count, select “Bremsenzaehler (DF_GetBrLiveTime)”. This
returns the total count to date. Stop here if only getting the count and backout of the menu using the F1 key.
----------------
Stuff happens and it sucks. Be prepared for anything. I still complain about the time the Chevy Chevette that I owned while attending university had a rear wheel bearing go bad; bearing overheated, melted the seals on the slave cylinder on the rear drum brake , and I lost all braking power (pedal to the floor!) with my wife and infant son in the car! After a sharp dose of adrenalin entering the bloodstream, I rapidly evaluated the situation, brought the car safely to a stop, and then drove it over 30 miles home on the Interstate using the parking brake when necessary. To make matters worse, that Chevette took most of my money to purchase. $250! Yep. My priorities were a bit different back then....

Quite possible after the lawyers get involved. Surely there is someone in the OP's area who can assist? If the OP were in my area I would be happy to be of service.
SBC has been replaced, picked it up this evening, and saved a few hundred bucks thanks to your advice!! beejAMG, are you looking to pick a fight? You're calling me a baby because I expressed my concerns over safety? Just because you aren't able readily find documentation of a fatality doesn't mean it hasn't happened, or that it won't. Recalls and class actions are meant to protect people (albeit, they aren't always used that way, but I digress). And in order for one to happen - people have to complain. You think corporations do it out of the goodness of their own hearts? I understand if you do not agree with my opinion, but belittling is neither appropriate nor constructive.
bbirdwell and cetialpha5, thanks for the informative posts. I've had the unit replaced, but checking on it every once in a while would give me some peace of mind. bbirdwell, I'm afraid I don't live near you, but thank you for your offer! I'm sure I can find someone in my area with the right tools.

Gave you my 2 cents on my first reply and you came back looking for lawsuits and stuff. wished you well on 2 different occasions already but you still keep coming. Some people...smh
Edit: ill save this thread so i can just copy paste the link for the next guy looking for a free ride.

Technicians in america get paid flat rate. NO tech in their right mind is going to willingly interrogate sbc when a relevant fault isn't present. That is in-efficiency to a T. Until something is broken or has failed nothing can accurately be diagnosed or replaced. Chasing a problem that isn't their is stupidity. SBC isn't really that bad when you think about it. The following chasis have sbc, 211-219-230.
So please, tell me how a lawyer involved will assist any help with the "free ride" people are begging for? There's a small fraction of sbc units that have gone bad in comparison to the vehicle sold with sbc. OP not saying you wanted a free ride, but it seems to me at least in the w211 thread people complain all the time about a mechanical moving part that fails.....
No offence mate, but this ship has sailed a long time ago. Nothing you mentioned hasnt been said or written from previous posts on this thread. So basically you just wasted your time and im just wasting mine now. Try reviving another thread mate ot better yet start a new thread about SBC so i can just copy paste this link to your new thread. That being said...where do i go to read something worthwhile.




You decide if the number compared to years and vehicles with SBC is alarming.
What is still a bit confusing is the backup system.
One of the drivers reported total failure with pedal to the floor. If you play with SBC on stop car - the pedal is going to the floor, or close to it all the time, but you don't push it in normal driving or your wheels would lock.
In this case we hear the story from passenger and I would gladly hear the actual driver side.
Did backup system really fail, or was it just first impression when pedal required much more effort to activate the brakes?
In one of the reported failure the driver said he could safely stop the car and then drive it some distance to a shop.
Lastly the end of counter for SBC activation is not failure. Per report the end of the counter is giving messages for several weeks before putting the car in limp mode.

Lately, thank to fellow forum member I was able to get copy of master inquiry and it did show SBC work in 2008.
The car, originating in NY had some corrosion on engine parts, while the pump look cleaner, so I did expect the pump to be newer, but nice to see confirmation.
I wish I still had my STAR/DAS system but I let it go with the V8 Crossfire. BTW, not too many dealers know about developer mode. It is in every system but requires a special WEP/Key to open it up and it is in German. I know because we used Developer mode to make a MB V8 ECU think it was supposed to be in a Chrysler Crossfire.
